[0001] The present disclosure relates to a window or door profile, such as a roof window
profile, and to a building window or door. Also, the present disclosure relates to
a method of providing an insulated window or door profile.
Background
[0002] Building window and building door profiles are continuously subject to improvements
in order to e.g. improve thermal insulation performance. In order to improve thermal
insulation performance, heat insulation material may be provided into the interior
of the profile. Some solutions suggest using expansion foaming (such as spraying expansion
foam) inside the profile during manufacturing of the profile to comprise an interior
heat insulation material.
[0003] EP 2 080 864 B1 discloses a solution wherein a profile is provided and comprises an insulating core
comprising a reinforcement. The insulating core is here reversibly deformable when
acted on by a force, and may comprise several, flexible lips projecting away from
an insulating solid body of the insulating core. These lips abut the inner wall of
an insulating chamber of the profile. This solution may provide drawbacks. For example,
it may provide an insulation solution resulting in drawbacks with respect to the insulation
performance and/or ease of installing the insulating core. Additionally or alternatively
it may provide a cost expensive solution. For example, the solution in
EP 2 080 864 B1 may provide high resistance/friction during insertion of the insulating core.
[0004] It may e.g. be a purpose of the present disclosure to provide a solution for a profile
for a building window or building door that is cost efficient and/or easy to provide
and which also provides good heat insulation performance.
Summary
[0005] The present disclosure relates, in a first aspect, to a window or door profile, such
as a roof window profile. The window or door profile comprises exterior walls providing
an outer profile boundary. The profile is elongated and extends in a longitudinal
direction. The exterior walls encloses at least one elongated chamber which extends
in the longitudinal direction of the profile. The profile comprises at least one elongated
insulation block which extends inside the elongated chamber in the longitudinal direction
of the profile. The elongated insulation block may comprise a foam insulation material.
The elongated insulation block comprises one or more interior spaces, wherein the
one or more interior spaces is elongated and extends in the longitudinal direction
of the elongated insulation block. The one or more interior spaces is arranged between
a first insulation body part and a second insulation body part of the elongated insulation
block. The first and second insulation body parts are interconnected by means of at
least one wall part of the elongated insulation block which is arranged opposite to
the one or more interior spaces. The one or more interior spaces may have a depth
which extends transverse to the longitudinal direction of the elongated insulation
block, wherein said depth extends over at least 50%, of the width of the insulation
block.
[0006] The solution according to embodiments of the present disclosure may e.g. provide
a solution which may be beneficial when providing heat insulation inside a window
or door profile having a complex interior shape. Additionally or alternatively, the
one or more interior spaces, such as one or more slits, may provide a solution where
the insulation material is more easy to insert into the profile chamber. Additionally
or alternatively, the one or more interior spaces may help to provide that the insulation
material is more easy to remove at end of life of the window or door, thereby providing
recycling advantages. The spaces may additionally or alternatively provide a solution
where the insulation material may be inserted also in profiles having profile surfaces
that may induce higher friction, e.g. due to surface roughness.
[0007] Moreover, the elongated insulation block is not provided by using expansion foaming
(such as spraying expansion foam) inside the profile during manufacturing of the profile
to comprise the interior heat insulation material. This may e.g. provide that the
profile wall material is not exposed to high temperatures generated in the foaming
process.
[0008] Computer simulations have indicated that even though one or more interior, elongated
spaces (in the simulated example it was slits) is/are provided in the insulation material,
the heat insulation performance may still be acceptable, and a U
frame value lower than 1.54 W/mK, such as lower than 1.52 W/mK, such as lower than 1.51
W/mK may be obtained after insulation insertion. This may even be obtained while at
the same time leaving certain areas of the elongated chamber unfilled with insulation
material of the insulation block.
[0009] The interior spaces may also help to adapt the final, compressed shape of the insulation
block to unevenness along the profile, e.g. unevenness originating from manufacturing
the profile with the desired cross sectional shape and length.
[0010] In one or more embodiments of the present disclosure, the one or more interior spaces
is/are filled with gas, such as air.
[0011] The window or door profile may in embodiments of the present disclosure be a frame
profile for a building door or building window.
[0012] In one or more embodiments of the present disclosure, the one or more interior spaces
may have a depth which extends transverse to the longitudinal direction of the elongated
insulation block wherein said depth extends over at least 50% of the width of the
insulation block at the area of the one or more interior spaces.
[0013] In one or more embodiments of the present disclosure, the one or more interior spaces
comprises one or more slits arranged in an outer surface of the elongated insulation
block. These one or more one slits may extend in a depth direction into the elongated
insulation block towards a slit bottom from a slit opening. The slit opening is arranged
in an outer surface of the elongated insulation block, and the at least one wall part
provides a bottom of the slits.
[0014] The slits may help to ease insulation block insertion (and in some embodiments also
removal) of the insulation block while the bottom walls may help to provide resiliency
and/or weakening to the profile that helps to push parts of the insulation block against
parts of the profile.
[0015] In one or more embodiments of the present disclosure, said slit bottom may be provided
by the bottom wall part of the elongated insulation block.
[0016] In one or more embodiments of the present disclosure, the one or more slits may extend
in a depth direction into the elongated insulation block towards a slit bottom from
an outer surface of the elongated insulation block, so that the at least one slit
provides a deflection space into which a part of the elongated insulation block extends
in response to a compression force subjected to the elongated insulation block inside
the elongated chamber providing the insulation block into a compressed state.
[0017] In one or more embodiments of the present disclosure, one or both of the first and
second body part may constitute at least 15%, such as at least 25%, such as at least
35% or at least 45%, of the total cross sectional area of the elongated insulation.
[0018] In one or more embodiments of the present disclosure, the one or more interior spaces
may comprise a first slit and a second slit arranged in outer surfaces of the elongated
insulation block, wherein the first slit and the second slit each extends in a depth
direction into the elongated insulation block towards a slit bottom from slit openings
in different outer surfaces of the elongated insulation block so that the first slit
and the second slit overlap and so that a partition wall part of the elongated insulation
block is arranged between the first slit and the second slit.
[0019] This may e.g. help to provide a desired compression property of the elongated insulation
block, and/or help to increase the compression range of the insulation block, such
as with a resulting, reduced compression of the body parts.
[0020] In one or more embodiments of the present disclosure, the one or more interior spaces
may be a first slit and a second slit arranged in outer surfaces of the elongated
insulation block, wherein the first slit and the second slit each extends in a depth
direction into the elongated insulation block towards a slit bottom from slit openings
in different outer surfaces of the elongated insulation block so that the first slit
and the second slit overlap and so that a partition wall part of the elongated insulation
block is arranged between the first slit and the second slit.
[0021] In one or more embodiments of the present disclosure, the different outer surfaces
of the elongated insulation block are oppositely directed. Additionally or alternatively,
in one or more embodiments of the present disclosure, the first depth direction and
the second depth direction may be substantially oppositely directed.
[0022] This may e.g. help to provide an advantageous controlled compression of the insulation
block.
[0023] In one or more embodiments of the present disclosure, the elongated insulation block
may comprise at least a first slit arranged in a first outer surface of the elongated
insulation block, and a second slit arranged in another, e.g. oppositely directed,
second outer surface of the elongated insulation block.
[0024] In some embodiments of the present disclosure, the first slit may extend into the
elongated insulation block from a first outer surface of the elongated insulation
block in a first depth direction, wherein the first slit has a first depth extending
from the first outer surface of the elongated insulation block to a slit bottom. Additionally
or alternatively, the second slit may extend into the elongated insulation block from
a second outer surface of the elongated insulation block in a second depth direction
and wherein the second slit has a second depth extending from the second outer surface
of the elongated insulation block to a slit bottom.
[0025] In one or more embodiments of the present disclosure, the elongated insulation block
may be in a compressed state in the elongated chamber.
[0026] In one or more embodiments of the present disclosure, the first and second insulation
body parts may be resiliently suspended, such as by means of one or more walls of
the elongated insulation block.
[0027] In one or more embodiments of the present disclosure, a partition wall part may,
for example directly or indirectly, interconnect bottom wall parts which provides
a bottom of different interior spaces.
[0028] In one or more embodiments of the present disclosure, the first and second insulation
body parts may be resiliently suspended by means of one or more bottom walls and at
least one partition wall of the elongated insulation block.
[0029] This may e.g. help to provide a desired compression properties and insulation properties
of the elongated insulation block, and/or help to increase the compression range of
the insulation block, such as with a resulting, reduced compression of the body parts.
[0030] In one or more embodiments of the present disclosure, said one or more walls, such
as the one or more bottom walls and the at least one partition wall, may be in a compressed
state, such as in a deflected state, in the elongated chamber.
[0031] This may help to provide a controlled compression of the insulation block so as to
control the area of compression of the elongated insulation block. This may e.g. help
to reduce compression of the first insulation body part and the second insulation
body part.
[0032] In one or more embodiments of the present disclosure, the elongated insulation block
is in the compressed state in the elongated chamber so that a cross sectional area
of the one or more interior spaces is reduced.
[0033] Providing that the compression of the elongated insulation block to the compressed
state (by the profile) in the elongated chamber is obtained by reducing the cross
sectional area of the one or more interior spaces may e.g. help to e.g. limit or even
substantially avoid compression of the insulation material itself at e.g. the first
and second insulation body parts. Additionally or alternatively. It may provide a
controlled deflection of the insulation block, which may provide benefits from an
insulation point of view and/or a durability point of view.
[0034] It is noted that the cross-sectional area of the one or more interior spaces, such
as slits, may be reduced when the insulation block is in a compressed state in the
profile chamber when compared to the cross sectional area of the one or more interior
spaces when the insulation block is in a substantially uncompressed state.
[0035] In one or more embodiments of the present disclosure, one or more of the one or more
interior spaces may provide a deflection space into which a part of the elongated
insulation block extends in response to a compression force subjected to the elongated
insulation block in a compression direction inside the elongated chamber. This may
in some embodiments e.g. occur in the said compressed state where the cross sectional
area of the interior space(s) is/are reduced.
[0036] This may help to reduce compression of the insulation material of the body parts
themselves.
[0037] It is understood that the interior spaces may provide controlled weakening areas
of the insulation block so that the compression of the insulation block is controlled
to mainly or only be provided at the desired areas, such as the areas at and/or near
the interior spaces.
[0038] In one or more embodiments of the present disclosure, the elongated insulation block
comprises a partition wall part placed between the first insulation body part and
a second insulation body part. Here, an interior space is arranged at each side of
the partition wall part.
[0039] In one or more embodiments of the present disclosure, at least one of the first and
second body part constitutes at least 25%, such as at least 35%, or at least 45% of
the total cross sectional area of the elongated insulation block.
[0040] In one or more embodiments of the present disclosure, each of the first and second
body part may constitute at least 15%, such as at least 25%, such as at least 35%
or at least 40%, of the total cross sectional area of the elongated insulation block.
[0041] In some embodiments of the present disclosure, the cross sectional area of the first
and second body parts may be substantially identical. In other embodiments of the
present disclosure, the cross sectional area of the first and second body parts may
be different so that the cross sectional area of one of the first and second body
parts is larger than the cross sectional area of the other of the first and second
body parts.
[0042] The cross sectional area of the elongated insulation block may in embodiments of
the present disclosure be defined by and enclosed by the outer/exterior boundary of
the elongated insulation block.
[0043] In one or more embodiments of the present disclosure, one of the first and second
body part may constitute more than 25%, of the total cross-sectional area of the elongated
insulation block, whereas the other of the first and second body part may constitute
at least 35%, of the total cross-sectional area of the elongated insulation block.
[0044] In one or more embodiments of the present disclosure, the elongated insulation block
may be resilient and thereby provides a counter force in response to a compression
force subjected to the elongated insulation block inside the elongated chamber. This
may e.g. help to improve heat insulation over time. In further embodiments of the
present disclosure, said counter force may be obtained due to the inherent resilient
properties of the insulation material of the insulation block. This may e.g. help
to provide improved heat insulation performance and/or a more cost efficient solution.
[0045] In one or more embodiments of the present disclosure, the elongated insulation block
may be compressed in a compression direction to a compressed state by means of one
or more contact surfaces, such as contact surfaces provided by walls and/or protrusions
of the profile.
[0046] In one or more embodiments of the present disclosure, said compression direction
may be at least partly transverse to the depth direction of the interior spaces, such
as slits, so that one or more wall side surfaces of the elongated insulation block
that abuts the at least one slit is moved into the at least one slit.
[0047] In one or more embodiments of the present disclosure, the one or more interior spaces
may comprise a first interior space and a second interior space, wherein the first
and the second interior space overlaps so that a partition wall part of the elongated
insulation block is arranged between the first interior space and the second interior
space.
[0048] This may e.g. help to increase the compression range of the insulation block.
[0049] In one or more embodiments of the present disclosure, one or both of the first and
second insulation body parts and/or a partition wall part of the elongated insulation
block may be configured so as to rotate at least partly around one or more rotation
axes in response to a deflection force provided by the profile, wherein said rotation
axis extends in the longitudinal direction of the elongated insulation block. This
may e.g. help to provide a mechanically simple solution for obtaining a controlled
compression of the elongated insulation block.
[0050] In one or more embodiments of the present disclosure, one or both of the first and
second insulation body parts and/or said partition wall part may be configured so
as to rotate around at least two rotation axes in response to a deflection force provided
by the profile, wherein said at least two rotation axes extends in the longitudinal
direction of the elongated insulation block. In further embodiments, the at least
two rotation axes may be arranged at different side portions of the elongated insulation
block. This may e.g. help to provide a mechanically simple solution for obtaining
a more controlled compression of the elongated insulation block so as to adapt to
the interior geometry of the elongated chamber of the profile. Additionally or alternatively,
it may help to obtained an increased compression range where also the compression
of the insulation body part(s) is reduced.
[0051] In one or more embodiments of the present disclosure, at least the partition wall
part of the elongated insulation block may be configured to provide said rotation
around the one or more rotation axes due to a deflection of the partition wall.
[0052] This may help to provide a controlled compression of the elongated insulation block.
[0053] In one or more embodiments of the present disclosure, said rotation axis or axes
may be defined by and/or arranged at the area of the at least one interconnecting
wall part and/or the partition wall.
[0054] In one or more embodiments of the present disclosure, the partition wall part comprises
a first partition wall side surface and a second partition wall side surface, wherein
the partition wall side surfaces are oppositely directed so that a first of the partition
wall side surfaces faces a first of the slits and a second of the partition wall side
surfaces faces the other of the slits, wherein each partition wall side surface extends
in the depth direction of the respective slit between the slit opening in the respective
outer surface and the slit bottom.
[0055] In one or more embodiments of the present disclosure, said slits together provides
an S-shaped and/or a Σ-shaped elongated insulation block when seen in cross section
in a plane that is perpendicular to the longitudinal direction of the elongated insulation
block.
[0056] In one or more embodiments of the present disclosure, said slits provide a corrugated
deflection portion of the insulation block. This is when seen in a cross-sectional
view of the elongated insulation block.
[0057] In one or more embodiments of the present disclosure, the elongated insulation block
is configured so that one or more of said one or more interior spaces, such as one
or more slits, has/have a slit height between 0.5 mm and 4 mm, such as between 0.5
and 2 mm, such as between 1 mm and 2 mm.
[0058] In one or more embodiments of the present disclosure, the elongated insulation block
is compressed by at least 1%, such as at by at least 3%, such as by at least 5% when
compared to the initial, uncompressed height of the elongated insulation block.
[0059] In one or more embodiments of the present disclosure, the elongated insulation block
is compressed by no more than 20%, such as no more than 15%, such as no more than
10%, such as no more than 7%, when compared to the initial, uncompressed height of
the elongated insulation block.
[0060] In one or more embodiments of the present disclosure, the depth of the one or more
interior spaces, such as one or more slits, extends over at least 60%, such as over
at least 70%, such as over at least 80% of the width of the elongated insulation block
at the area of the interior space.
[0061] This may e.g. provide an insulation block having "softer" compression properties
and/or help to reduce friction when inserting the insulation block in the profile
chamber.
[0062] In one or more embodiments of the present disclosure, said width of the elongated
insulation block may be defined between oppositely directed, exterior surfaces of
the insulation block.
[0063] In one or more embodiments of the present disclosure, the depth of the interior spaces,
such as one or more slits, extends into less than 95%, such as less than 90%, such
as less than 85% of the width of the elongated insulation block at the area of the
slit.
[0064] This may e.g. help to remain a counter force in response to a compression force subjected
to the elongated insulation block inside the elongated chamber, due to the resiliency
of the elongated insulation block 1. It may additionally or alternatively help to
maintain resiliency of the insulation block over time.
[0065] In one or more embodiments of the present disclosure, the elongated insulation block
may rest one or more elongated protrusions of the profile which extends into the chamber,
wherein the elongated protrusions extend in the longitudinal direction of the profile.
In one or more further embodiments, one or more of the one or more elongated protrusions
may comprise reinforcement protrusions.
[0066] Such protrusions may help to provide a profile having desired characteristic. For
example, providing reinforcement protrusions/ridges, such as discrete protrusions/ridges,
extending inside the profile chamber may help to provide a visually appealing profile
while also providing a profile having a desired strength. The inventor has found that
it may be acceptable that the insulation block rests on such protrusions. The insulation
block may not extend in between neighboring protrusions/ridges, as this may increase
friction during insulation block insertion, and the inventor has realized that acceptable
insulation performance may still be obtained.
[0067] In one or more embodiments of the present disclosure, the one or more elongated protrusions
may provide some or all of said compression of the elongated insulation block to the
compressed state. This may e.g. help to reduce friction upon insertion of the elongated
insulation block. The elongated insulation block may e.g. support on a surface of
the one or more protrusions.
[0068] In one or more embodiments of the present disclosure, an air gap of at least 1 mm,
such as at least 2 mm is provided between the elongated insulation block and one or
more of the exterior profile walls. In one or more embodiments of the present disclosure,
an air gap of between least 1 mm and 5mm, such as between 2mm and 5 mm is provided
between the elongated insulation block and one or more of the exterior profile walls.
This may e.g. help to reduce friction upon insulation block insertion
[0069] In one or more embodiments of the present disclosure, the air gap is arranged next
to or between neighboring, discreet protrusions of the profile.
[0070] In one or more embodiments of the present disclosure, the body parts may be solid
in the sense that substantially no holes, gaps, openings, slits and/or the like are
provided other than pockets, such as air/gas pockets, provided by inherent properties
of the insulation material itself.
[0071] This may e.g. provide a desired, resilient solution where the insulation block is
compressible while also a main part/parts of the insulation may not be deformed/compressed,
or may only be limited deformed, as the deformation by compressing the insulation
block is primarily facilitated by the bottom wall part(s) of the insulation block.
[0072] In one or more embodiments of the present disclosure, the elongated insulation block
is a substantially monolithic structure. This may e.g. help to provide advantageous
compression properties of the insulation block and/or provide advantages with regards
to recycling after end of life of the window or door. Additionally or alternatively,
it may provide a cost efficient and/or more mechanically simple insulation solution.
[0073] In one or more embodiments of the present disclosure, the elongated insulation block
is without interior reinforcements. In one or more embodiments of the present disclosure,
the elongated insulation block is without interior reinforcements of another material
and/or density than the insulation material of the elongated insulation block.
[0074] Omitting interior reinforcements in the elongated insulation block may e.g. provide
a cost efficient and/or more mechanically simple insulation solution. Additionally
or alternatively, it may provide advantages with regards to improved thermal insulation
performance.
[0075] Providing that the elongated insulation block is without interior reinforcements
of another material and/or density than the insulation material of the elongated insulation
block may e.g. provide advantages with regards to obtaining advantageous compression
properties of the insulation block and/or providing advantages with regards to recycling
after end of life of the window or door.
[0076] In one or more embodiments of the present disclosure, the elongated insulation block
may be un-bonded to the profile.
Hence, no glue or other chemical and/or mechanical bonding solution may be provided
between the insulation block and the profile walls: This may e.g. help to improve
recyclability at end of life of the window or door.
[0077] In one or more embodiments of the present disclosure, the insulation material of
the elongated insulation block may have a density between 25 kg/m
3 and 70 kg/m
3, such as between 28 kg/m
3 and 60 kg/m
3, for example between 30 kg/m
3 and 45 kg/m
3.
[0078] This may provide a relatively hard insulation block that may provide e.g. one or
more advantages in relation to insulation block insertion in the profile chamber and/or
relating to the structural integrity over time of the insulation block. Additionally
or alternatively, it may provide advantages in relation to heat insulation properties
and/or provide a desired resiliency of the insulation block (when the one or more
spaces is/are provided). It may additionally or alternatively provide that the body
parts are less compressed when the insulation block a whole is compressed into a compressed
state inside the profile chamber.
[0079] In one or more embodiments of the present disclosure, the insulation material of
the elongated insulation block has a U-value of less than 0.040 W/mK, such as less
than 0.0350 W/mK. In some embodiments of the present disclosure, the insulation material
of the elongated insulation block has a U-value between 0.025 W/mK, and 0.045 W/mK,
such as between 0.03 W/mK, and 0.04 W/mK.
[0080] This may e.g. provide an insulation block with acceptable heat insulation performance.
[0081] In one or more embodiments of the present disclosure, the foam insulation material
of the elongated insulation block may comprise, such as be, an expanded polypropylene
insulation material, such as a closed cell expanded polypropylene insulation material.
[0082] In other embodiments of the present disclosure, the foam insulation material of the
elongated insulation block may be an Expanded Polystyrene (EPS) foam, or a Polyvinyl
Chloride (PVC) foam.
[0083] In one or more embodiments of the present disclosure, one or both interior spaces,
such as slits, extends continuously in the longitudinal direction of the elongated
insulation block between the opposite ends of the elongated insulation block.
[0084] This may e.g provide an insulation block that is easy to insert in the profile chamber
and/or which is easy to manufacture.
[0085] In one or more embodiments of the present disclosure, a plurality of said interior
spaces, such as slits, extend between the opposite ends of the elongated insulation
block, wherein the consecutively arranged, interior spaces are separated by intermediate
walls in the insulation material. This may e.g. provide a solution where the resistance
against compression of the insulation block may be controlled by the intermediate
walls, such as based on the thickness of the intermediate walls, the number of intermediate
walls per length of the insulation block and/lor the like. Additionally or alternatively,
it may provide a more long-lasting solution.
[0086] These intermediate walls may be designed to maintain a certain degree of stiffness
at abrupt portions of the insulation block along the insulation block length.
[0087] In one or more embodiments of the present disclosure, the one or more interior, elongated
spaces, such as slits, may be pre-shaped in the elongated insulation block and may
have been provided at predefined locations of the elongated insulation block.
[0088] In one or more embodiments of the present disclosure, the one or more interior, elongated
spaces, such as slits, may be present as a result of a manufacturing solution involving
one or more of:
- machining the one or more interior spaces (S1, S2), such as slits, into the elongated
insulation block,
- melting the one or more interior spaces (S 1, S2), such as slits, into the elongated
insulation block, and/or
- molding, extruding or compressing/pressing the elongated insulation block during insulation
block shaping/manufacturing so as to provide an elongated insulation block comprising
the one or more interior spaces (S 1, S2), such as slits.
[0089] In one or more embodiments of the present disclosure, the elongated insulation block
has a length which extends over substantially the entire length of the profile.
[0090] In one or more embodiments of the present disclosure, wherein at least 50%, such
as at least 80%, such as at least 95% of the compression of the elongated insulation
block inside the profile is provided by means of one or more insulation body parts
of the elongated insulation block extending into the one or more interior spaces due
to the compression of the elongated insulation block. Hence, the cross-sectional area
of the one or more interior spaces may be reduced upon insertion of the elongated
insulation block into the profile chamber. The reduction of the cross-sectional area
of the one or more spaces may adapt to the interior shape of the profile chamber over
the length of the profile.
[0091] In one or more embodiments of the present disclosure, the elongated insulation block
may be in the compressed state in the elongated chamber so that at least 50%, such
as at least 80%, such as at least 95% of the compression (H1→H2) of the elongated
insulation block in a compression direction is provided by means of a reduction of
the cross sectional area of the one or more interior spaces when compared to the cross
sectional area of the one or more interior spaces when the elongated insulation block
is in a substantially uncompressed state.
[0092] Hereby, the compression of the insulation of the body parts is reduced or substantially
avoided.
[0093] In one or more embodiments of the present disclosure, the window or door profile
comprises a first and a second elongated chamber. A first of said elongated insulation
block may be arranged in the first elongated chamber, and a second of said elongated
insulation block may be arranged in the second elongated chamber.
[0094] This may e.g. improve insulation performance of the profile.
[0095] In some embodiments of the present disclosure, the first insulation block may be
arranged opposite to a support wall of the profile which is configured to support
a major surface of a glass unit. Additionally or alternatively, in some embodiments
of the present disclosure, the second insulation block may be arranged opposite to
a profile wall which is configured to be arranged opposite to a side edge surface
of the insulating glass unit.
[0096] In one or more embodiments of the present disclosure, the cross sectional area of
the elongated insulation block may take up less than 90%, such as less than 80%, such
as less than 72% or less than 65% of the total cross sectional area of the elongated
chamber.
[0097] This may e.g. help to provide a solution where less friction occur when inserting
the insulation block. Additionally or alternatively, it may help provide a solution
where a more complex interior profile shape may be allowed while at the same time
allowing more easy insulation block insertion over the profile length. For example,
interior reinforcement protrusions, complex (such as acute) wall angles and or the
like of the profile may be allowed in the compartment without the insulation block
necessarily filling out minor spaces around these complex shapes. However, also larger,
straight surfaces facing the interior chamber of the profile may not be in touch with,
or may only be partly in touch with the insulation block.
[0098] In one or more embodiments of the present disclosure, the profile may not be completely
straight, at least prior to installation of a window profile and/or prior to attachment
of other profiles to that profile. The insulation material may adapt to the unevenness
of the profile due to the resiliency provided by the one or more interior spaces of
the insulation block and/or the cross-sectional dimension of the insulation block.
This may hence help to provide a solution where it may be more easy to insert the
insulation block and still the insulation block may adapt due to it's resiliency so
as to adapt to the shape of the profile in the longitudinal direction of the profile.
[0099] In one or more embodiments of the present disclosure, the cross-sectional area of
the elongated insulation block may take up less than 90%, such as less than 80%, such
as less than 72% or less than 65% of the total cross sectional area of the elongated
chamber over at least 50%, such as at least 70% or at least 80% of the length of the
profile.
[0100] This may help to reduce friction and the inventor has found by simulation that an
acceptable heat insulation degree of the profile may still be obtained even though
the insulation block does not completely fill out the total cross section of the elongated
chamber (2, 20). For example, in some embodiments of the present disclosure, a U-frame
value lower than 1.54 W/mK, such as lower than 1.52 W/mK, such as lower than 1.51
W/mK may be obtained after insulation block insertion.
[0101] In one or more embodiments of the present disclosure, the cross-sectional area of
the elongated insulation block takes up at least 50% such as at least 60%, such as
at least 65% of the total cross sectional area of the elongated chamber.
[0102] This provides an improved heat insulation performance.
[0103] In one or more embodiments of the present disclosure, the cross-sectional area of
the elongated insulation block may take up at least 50% such as at least 60%, such
as at least 65% of the total cross sectional area of the elongated chamber over at
least 50%, such as at least 70% or at least 80% of the length of the profile.
[0104] In one or more embodiments of the present disclosure, the one or more interior spaces
provides a wakened portion of the elongated insulation block, and thereby a deflection
area/section providing that the majority of the compression of the elongated insulation
block is provided at the area of the one or more interior spaces.
[0105] In one or more embodiments of the present disclosure, the wakened portion provides
that at least 50%, such as at least 80%, such as at least 95% of the compression of
the elongated insulation block is provided by means of one or more insulation body
parts of the elongated insulation block extending into the one or more interior spaces
due to the compression of the elongated insulation block. This may help to omit the
reduction of, or reduce the reduction of, the cross-sectional area of the body part(s)
when the elongated insulation block is placed in the elongated profile chamber.
[0106] In one or more embodiments of the present disclosure, the elongated insulation block
may be compressed inside the profile so that the height of the elongated insulation
block is reduced whereas the insulation block remains substantially uncompressed in
the width direction of the profile.
[0107] The present disclosure moreover, in a second aspect, relates to a building window
or door, such as a roof window or a facade window, comprising a frame. The frame comprises
a plurality of profiles according to one or more of the previously disclosed embodiments.
The profiles of the frame together provides a rectangular frame with a frame opening,

insulating glass unit.
[0111] In one or more embodiments of the second aspect, the building window is a roof window
configured to be / designed to be installed in a roof structure of a building, such
as with an angle which is larger than 17°, such as larger than 30° with respect to
horizontal.
[0112] In one or more embodiments of the second aspect, the design of the window and the
one or more interior spaces is configured so as provide that a plurality of isotherm
lines extends through the one or more interior spaces in a direction transverse to
the depth direction of the one or more interior spaces when the building window is

Detailed description
[0124] Fig. 1 illustrates schematically a cross section of a window or door profile 1, according
to embodiments of the present disclosure. In fig. 1, the profile 1 is a profile of
a frame 100 of a roof window 200, but it may also be a frame of another type of building
window or building door, in other embodiments of the present disclosure.
[0125] The frame 100 comprises one or more of said profile 1, such as e.g. two, three or
four of said profile 1. The frame 100 provides/frames a frame opening FO. The frame
100 supports a glass unit such as an insulated glass unit 12.
[0126] The insulated glass unit 12 comprises a plurality of glass sheets 12_1-12_4. In the
embodiment of fig. 1, the glass unit 12 is a triple pane glass unit comprising an
intermediate glass sheet 12_2 and two outer glass sheets 12_1, 12_3. Insulating spaces
12-IN are placed between the intermediate glass sheet 12_2 and the respective outer
glass sheet 12_1, 12_3. The insulating spaces 12-IN may be filled with a gas or may
be evacuated. If evacuated, the glass unit 12 may be a vacuum insulated glass unit
(VIG), and a plurality of spacers (not illustrated), such as pillars, may be distributed
in the insulating space 12-IN to maintain a distance between the glass sheets.
[0127] Edge seals 13 seal the insulating spaces 12_IN between the glass sheets 12_1, 12_2,
12_3. The edge seal 13 type may be selected dependent on the glass unit 12 type.
[0128] In fig. 1, the glass unit 12 is a laminated glass unit and comprises a glass sheet
12_4 that adhere to the glass sheet 12_3 by means of a lamination interlayer 12_4i
, such as a PVB (Polyvinyl butyral) or EVA (Ethylene-vinyl acetate) interlayer.
[0129] It is understood that in some embodiments of the present disclosure, just one insulating
space 12-IN may be provided and the glass unit 12 may comprise just two glass sheets
(and e.g. also the lamination glass 12_4). In further embodiments, more than two insulating
spaces/gaps 12-IN, and hence also more glass sheets, may be provided.
[0130] The 12 glass unit comprises outer major surfaces 12a, 12b (coated or uncoated) provided
by the glass sheets 12_1 and 12_4 respectively, and a side edge 12e having a surface
extending between the outer major surfaces 12a, 12b.The surface of the side edge 12e
extends between the exterior major surfaces 12a, 12b of the insulating glass unit.
[0131] The exterior major surface 12a is configured to face the interior INT of a building
when the window 200 is installed in the building, and the exterior major surface 12b
is configured to face the exterior EXT of the building.
[0132] If the glass unit 12 is un-laminated, the outer major surface 12a may instead be
provided by e.g. the glass sheet 12_2 or 12_3 dependent on the glass unit type.
[0133] The profile 1 comprises exterior walls 3a-3e providing an outer/exterior profile
boundary PB defined by the exterior surface of the profile. This profile boundary
PB is indicated by means of a more bold line, which indicates the outer surface of
the profile 1.
[0134] One or more parts of the outer surface providing the outer boundary PB may be visible
to the human user after the profile is used/installed to provide a frame such as a
window frame or a door frame and when the frame is installed to provide a window or
door.
[0135] In embodiments of the present disclosure, the exterior walls 3a-3e are structural
walls.
[0136] In embodiments of the present disclosure, the exterior walls 3a-3e may comprise or
be made from a polymer.
[0137] In embodiments of the present disclosure, the walls 3a-3e may be PVC (Polyvinyl Chloride)
walls, such as Chlorinated Polyvinyl Chloride (CPVC) walls. In other embodiments,
the exterior walls 3a-3e may be Polypropylene (PP) walls, such as reinforced Polypropylene
walls, e.g. reinforced by means of glass fibers and/or carbon fibers. It is generally
understood that in some embodiments, fibers may be blended into the wall 3a-3e material
of the exterior walls 3a-3e so as to provide reinforced profile walls.
[0138] The profile 1 is elongated and extends in an longitudinal direction (not illustrated
in fig. 1, see e.g. figs. 11 and 12). The exterior walls 3a-3e encloses at least one
elongated chamber 2, 20 which extends in the longitudinal direction LD1 of the profile
1.
[0139] In the embodiment of fig. 1, The exterior walls 3a-3e encloses two elongated chambers
2, 20, but it is understood that in further embodiments of the present disclosure,
more than two, such as three, four, five or even more elongated chambers may be present
and be separated by partition walls 1w of the profile, or just one chamber is present
in the profile 1.
[0140] In fig. 1, a partition wall 1w of the profile 1 is integrated in the profile 1, and
separates the two chambers 2, 20. In Fig. 1, the partition wall 1w of the profile
extends from the wall 3e comprising the exterior surface 3e_es facing away from the
frame opening FO provided by the frame 100 and arranged opposite to the wall 3b comprising
the exterior surface 3b_es facing and abutting the frame opening FO. The partition
wall 1w of the profile 1 extends to an exterior wall 3c of the profile which provides
a recess for receiving an edge of the insulated glass unit 12.
[0141] It can be seen that the wall 3a extends between the first corner A and second corner
B, and that the wall 3B comprising the surface facing the frame opening FO extends
between the second corner B and the third corner C. The Third corner C is located
proximate to and opposite to the exterior major surface 12a configured to face the
building interior INT when the window 200 is installed in a building. The wall 3c
(comprising wall part 3c1 and 3c2) extends between the third C and fourth D corner
and comprises the corner part 3CC. The top wall 3d extends between the fourth corner
D and a fifth corner E. The Wall 3e extends between the fifth E and the first corner
A, and may comprise one or more recesses 17 or the like for holding a gasket (not
illustrated) such as a resilient gasket, such as a rubber gasket or the like, configured
to provide water tightening and/or air tightening between a fixation frame (not illustrated
in fig 1) and the frame 100.
[0142] The exterior wall 3c of the profile 1 extends between the top wall 3d and the wall
3b facing the frame opening FO, and provides a recess for receiving an edge of the
insulated glass unit 12. The wall 3c hence comprises a first 3c1 and a second 3c2
wall part, which meet at a corner portion 3cc, in order to provide the recess. The
wall part 3c 1 supports a part of the major surface of the glass unit 12 (e.g. with
gasket and/or glue between the wall 3c1 and the glass unit. The wall part 3c2 is placed
opposite to a side edge of the glass unit 12. The partition wall 1w may be unitary
with the exterior walls 3e, 3c.
[0143] The exterior surfaces 3a_es and 3b_es of the walls 3a and 3b may be visible from
the inside INT of the building by human eye when the window 200 is installed in the
building such as in a roof structure of the building.
[0144] The profile 1 comprises at least one elongated insulation block 4, 40 which extends
inside the elongated chamber 2, 20 in the longitudinal direction LD1 of the profile
1. In fig. 1, two insulation blocks are provided, and are arranged in each their elongated
chamber 2, 20.
[0145] The elongated insulation blocks 4,40 each comprises a foam insulation material.
The foam insulation material of the elongated insulation block 4, 40 may in embodiments
of the present disclosure consist of or comprise, such as be, an expanded polypropylene
insulation material, such as a closed cell expanded polypropylene insulation material.
In other embodiments of the present disclosure, the foam insulation material of the
elongated insulation block may comprise or consist of, such as be, an expanded Polystyrene
(EPS) foam, or a Polyvinyl Chloride (PVC) foam.
[0146] It is generally understood that in embodiments of the present disclosure, the insulation
material of the elongated insulation block 4, 40 may have a density between 25 kg/m
3 and 70 kg/m
3, such as between 28 kg/m
3 and 60 kg/m
3, for example between 30 kg/m
3 and 45 kg/m
3.
[0147] In some embodiments of the present disclosure, the insulation material of the elongated
insulation block 4, 40 has a U-value of less than 0.040 W/mK, such as less than 0.0350
W/mK,
[0148] In some embodiments of the present disclosure, the insulation material of the elongated
insulation block 4, 40 has a U-value between 0.025 W/mK, and 0.045 W/mK, such as between
0.03 W/mK, and 0.04 W/mK.
[0149] As can be seen from fig. 1, the elongated insulation block 4 comprises one or more
interior spaces S1, S2. In the embodiment of fig. 1, the elongated insulation block
4 comprises two spaces, i.e. a first space S1 and a second space S2, but in further
embodiments of the present disclosure, further spaces, such as three, four or five
spaces, may be provided (not illustrated in fig. 1.). In one embodiment of the present
disclosure, a single space may be provided (not illustrated in fig. 1.). The one or
more interior spaces S1, S2 is/are elongated and extends in the longitudinal direction
LD2 of the elongated insulation block 4, 40. See e.g. one embodiment hereof in
fig. 4.
[0150] The interior spaces S1, S2 are arranged between a first insulation body part BP1
and a second insulation body part BP2 of the elongated insulation block 4, 40.
[0151] In one or more embodiments of the present disclosure, the one or more interior spaces
S1, S2 in the elongated insulation block is/are filled with gas such as air.
[0152] The one or more interior spaces S1, S2 may in embodiments of the present disclosure
be in fluid communication with the elongated chamber 2, 20. In fig. 1, the interior
spaces S1, S2 of the elongated insulation block 4 is in fluid communication with the
elongated chamber 2, whereas the interior spaces S1, S2 of the elongated insulation
block 40 is in fluid communication with the elongated chamber 20. The one or more
interior spaces S1, S2 are in fig. 1 in fluid communication with the elongated chamber
2, 20 die to the slit openings SO1, SO2 (See fig. 2)
[0153] The first and second insulation body parts BP1, BP2 are interconnected by means of
wall parts 7 of the elongated insulation block 4, 40 which is arranged opposite to
the one or more interior spaces S1, S2 and provides a bottom wall.
[0154] In fig. 1, the elongated insulation block 4, 40 comprises a partition wall part 4W,
40W. This partition wall part is placed between the first insulation body part BP1
and the second insulation body part BP2 so that the interior spaces S1, S2 are arranged
at each side of the partition wall part 4W, 40W. Hence, the insulation body parts
BP1, BP2 are suspended from each other by means of the bottom wall parts 7 and the
partition wall 4W, 40W that interconnects the bottom wall parts 7. This provides that
the first and second insulation body parts BP1, BP2 are resiliently suspended, by
means of the bottom wall part 7 and the partition wall 4W, 40W. Accordingly, when
the profile 1 provides a compression force so that the insulation block 1 in the cavity
2, 20 is compressed, the primary part of the compression, or substantially the entire
part of the compression of the insulation block 1, may be provided by deflecting the
partition wall 4W, 40W and possibly also a part of the bottom wall 7 and/or a limited
area of one or both body parts BP1, BP2 located proximate the bottom wall 7. Hence,
the major part of the body parts BP1, BP2 may remain substantially uncompressed.
[0155] In some embodiments of the present disclosure, at least 50%, such as at least 80%,
such as at least 95% of the compression of the height H1 (See fig. 2) of the elongated
insulation block 4, 40 inside the profile 1 cavity 2, 20 is provided by that one or
more insulation body parts BP1, BP2 of the elongated insulation block 4, 40 extending
into the one or more interior spaces S1, S2 due to the compression of the elongated
insulation block 4, 40. Accordingly, a partly or limited compression of the insulation
body parts BP1, BP2 may occur, but it may be so that the major part of the compression
from H1 to H2 is provided by means of one or more of the insulation body parts BP1,
BP2 of the elongated insulation block 4, 40 extending into the one or more interior
spaces S1, S2 due to the compression.
[0156] It can be seen that the insulation body parts BP1, BP2 of the elongated insulation
block 4, 40 extends into the one or more interior spaces S1, S2 (In fig. 1 and 2,
the interior spaces are slits) due to the compression. This may as illustrated in
fig. 2 provide that the height of the slit S1, S2 and/or the height of the slit opening(s)
SO1, SO2 is reduced due to the compression force in the compression direction CD.
[0157] The compression direction may in embodiments of the present disclosure, be transverse
to, such as perpendicular to, the plane PL1.
[0158] When compressed by the profile 1, the elongated insulation block 4, 40 provides a
counter force in response to a compression force subjected to the elongated insulation
block inside the elongated chamber 2, 20, due to the resiliency of the elongated insulation
block 1.
[0159] In embodiments of the present disclosure, one or more of the interior spaces S1,
S2, such as one or more slits, may has/have a slit height SH (see fig. 2) less than
4 mm such as less than 3 mm, such as less than 2 mm. This may at least be the case
when the insulation block 4, 40 is compressed, and may be the slit height for the
major part or the whole part of the slit depth extension.
[0160] In embodiments of the present disclosure, one or more of the interior spaces S1,
S2, such as one or more slits, may has/have a slit height SH (see fig. 2) between
0.5 mm and 4 mm, such as between 0.5 and 2 mm, such as between 1 mm and 2 mm, at least
when the elongated insulation block 4, 40 is in a substantially uncompressed state
US. This height is reduced when the elongated insulation block is compressed by the
profile 1.
[0161] In one or more embodiments of the present disclosure, at least one of the first and
second body part BP1, BP2 may constitute at least 25%, such as at least 35%, or at
least 45% of the total cross sectional area of the elongated insulation block 4, 40.
[0162] In one or more embodiments of the present disclosure, the first body part BP1 may
constitute at least 15%, such as at least 25%, such as at least 35% or at least 45%,
of the total cross sectional area of the elongated insulation block 4, 40.
[0163] In one or more embodiments of the present disclosure, the second body part BP2 may
constitute at least 15%, such as at least 25%, such as at least 35% or at least 45%,
of the total cross sectional area of the elongated insulation block 4, 40.
[0164] In one or more embodiments of the present disclosure, each of the first and second
body part BP1, BP2 constitutes at least 15%, such as at least 25%, such as at least
35%, or at least 40% of the total cross sectional area of the elongated insulation
block (4, 40).
[0165] In one or more embodiments of the present disclosure, the first body part BP1 may
constitute less than 50%, such as less than 40%, of the total cross sectional area
of the elongated insulation block 4, 40.
[0166] In one or more embodiments of the present disclosure, the second body part BP2, may
constitute less than 50%, such as less than 40%, of the total cross sectional area
of the elongated insulation block 4, 40.
[0167] In some embodiments of the present disclosure, the cross sectional area of the first
and second body parts BP1, BP2 may be substantially identical. In other embodiments
of the present disclosure, the cross sectional area of the first and second body parts
BP1, BP2 may be different so that the cross sectional area of one of the first and
second body parts is larger than the cross sectional area of the other of the first
and second body parts.
[0168] In some embodiments, the interconnecting partition wall part 4W, 40W arranged between
the spaces S 1, S2 interconnects the bottom wall parts 7 which are arranged opposite
to a bottom SB1, SB2 of the interior space S 1, S2.
[0169] In figs. 1 and 2, the interior spaces S1, S2 comprises slits arranged in an outer
surface 4a, 40a, 4b, 40b of the elongated insulation block 4, 40. The slits S1, S2
extends in a depth direction DD1, DD2 into the elongated insulation block 4, 40 towards
a slit bottom SB1, SB2 from an outer surface 4a, 40a, 4b, 40b of the elongated insulation
block 4, 40. The wall part 7 comprises/provides a bottom wall part 7 which is arranged
opposite to a bottom SB1, SB2 of the one or more slits S 1, S2.
[0170] It is understood that in embodiments of the present disclosure, the slit(s) S1, S2
may be considered grooves or slots. The slits S 1, S2 may be long (in the longitudinal
direction of the insulation block) and narrow (in the height direction HD) channels
in a surface 4a, 4b of the insulation block 4, 40, and the slits extend into the insolation
block in the depth direction DD1, DD2.
[0171] In figs. 1 and 2, the slits comprises a first slit S1 and a second slit S2. The first
slit S1 and the second slit S2 each extends in the depth direction DD1, DD2 into the
elongated insulation block 4, 40 towards the slit bottom SB1, SB2 from different outer
surfaces 4a, 40a, 4b, 40b of the elongated insulation block 4, 40 so that the first
S1 and the second S2 slit overlaps and so that the partition wall part 4W, 40W of
the elongated insulation block 4, 40 is arranged between the first slit S1 and the
second slit S2.
[0172] In figs. 1 and 2, the different outer surfaces 4a, 40a, 4b, 40b are oppositely directed.
[0173] Additionally, as illustrated, the first depth direction DD1 and the second depth
direction DD2 may be substantially oppositely directed.
[0174] In some embodiments of the present disclosure, this partition wall 4W of the insulation
block may have a thickness that is less than 1/5, such as less than 1/8 or less than
1/10 of the uncompressed height H1 of the insulation block 4, 40. The height H1, H2
extends in a height direction HD.
[0175] In fig. 1 and fig. 2, the slits provides an S-shaped, elongated insulation block
4, 40 when seen in cross section in a plane that is perpendicular to the longitudinal
direction LD1 of the elongated insulation block 4, 40.
[0176] Fig. 2 illustrates a cross section of an elongated insulation block 4, according
to embodiments of the present disclosure in an uncompressed state US (left) and a
compressed state CS (right), respectively. The insulation block 4 in fig. 2 substantially
corresponds to the insulation block 4 illustrated in fig. 1.
[0177] The interior spaces S1, S2 has/have a depth SD1, SD2 which extends in a depth direction
transverse to the longitudinal direction of the elongated insulation block 4, 40.
This depth SD1, SD2 may in embodiments of the present disclosure extend over at least
30%, such as over at least 50%, of the width W1 of the insulation block 4, 40 at the
area of the respective one or more interior spaces S1, S2.
[0178] The width W1 extends in a width direction WD. The height direction HD and width direction
WD may be perpendicular to each other.
[0179] In some embodiments of the present disclosure, the depth SD1, SD2 of the one or more
interior spaces S1, S2, may extend over at least 60%, such as over at least 70%, such
as over at least 80% of the width W1 of the elongated insulation block 4, 40 at the
area of the interior space S1, S2.
[0180] In some embodiments of the present disclosure, the depth SD1, SD2 of the interior
space S1, S2 may extend into less than 95%, such as less than 90%, such as less than
85% of the width W1 of the elongated insulation block 4, 40 at the area of the slit
S1, S2.
[0181] The width W1 may be defined between the edge of the slit opening SO1, SO2 and perpendicular
to the longitudinal direction LD2 of insulation block (4, 40). For example, the width
W1 may be defined in a direction that may be substantially parallel to the plane PL1
and/or substantially parallel to the depth direction DD1, DD2. The width W1 may be
defined between the opposing surface 4a, 4b, 40a, 40b.
[0182] For example, in some embodiments of the present disclosure, the depth SD1, SD2 of
the one or more interior spaces S1, S2, may extend between 50% and 95%, such as between
60% and 95%, such as between 70% and 95% of the width W1 of the elongated insulation
block 4, 40 at the area of the interior space S1, S2.
[0183] The elongated insulation block 4,40 is compressed in a compression direction CD to
a compressed state CS by means of one or more contact surfaces, see fig. 1 and 2.
In the embodiment of fig. 1, the contact surfaces for the insulation block are provided
by walls 3a, 3c1, and/or protrusions 8, 9 thereof. The partition wall 1W may possibly
also provide support for the insulation block.. However, e.g. the wall 3b may provide
substantially no support for the insulation block 4, or the support may at least be
reduced when compared to the support provided by the walls 3c1 and 3a.
[0184] The oppositely directed surfaces SU1, SU2 of the insulation block 4 may in embodiments
abut the contact surfaces, such as surfaces of the protrusion(s) 8, 9.
[0185] As can be seen from e.g. fig. 1, The cross section of the insulation block 40, 4
may not completely fill the elongated chamber 2, 20. For example, as can be seen for
the chamber 2, the chamber(s) 2 may have a relatively complex cross sectional shape
provided by e.g. protrusions 8, 9 and walls of the profile. The complex cross sectional
shape may originate from features providing advantages with regard to e.g. reduction
of material use and/or CO2 footprint, improving insulation performance and/or the
like. However, the complex cross sectional shape may also be less desirable from the
perspective of introducing an insulation block into the chamber, e.g. due to risk
of increased friction caused by larger surface area and/or friction caused by corners,
small gaps, steep, such as acute, angles and/or the like and the like. However, according
to some embodiments of the present disclosure, the cross sectional area of the elongated
insulation block 4, 40 may take up less than 90%, such as less than 80%, such as less
than 72% or less than 65% of the total cross sectional area of the elongated chamber
2, 20. This may e.g. help, together with the interior spaces S1, S2, to provide a
solution where less friction occur when inserting the insulation block.
[0186] In one or more embodiments of the present disclosure, the profile may not be completely
straight, at least prior to installation of a window profile 1 and/or prior to attachment
of other profiles to that profile 1. The insulation block 4, 40 shape may adapt to
the local unevenness of the profile over the profile length due to the resiliency
provided by the one or more interior spaces S1 S2 of the insulation block and/or the
cross sectional dimension of the insulation block 4, 40. This may hence help to provide
a solution where it may be more easy to insert the insulation block in chambers 2,
20 with complex shapes, and still the insulation block may adapt due to it's controlled
resiliency provided by the interior spaces S1, S2 so as to adapt to the shape of the
profile in the longitudinal direction of the profile.
[0187] In some embodiments of the present disclosure, the cross sectional area of the elongated
insulation block 4, 40 may take up less than 90%, such as less than 80%, such as less
than 72% or less than 65% of the total cross sectional area of the elongated chamber
2, 20 over at least 50%, such as at least 70% or at least 80% of the total length
of the profile 1.
[0188] In some embodiments of the present disclosure, the cross sectional area of the elongated
insulation block 4, 40 may take up less than 80% of the total cross sectional area
of the elongated chamber 2, 20 over at least 70% or at least 80% of the total length
of the profile 1.
[0189] In some embodiments of the present disclosure, the cross sectional area of the elongated
insulation block 4, 40 may take up at least 50% such as at least 60%, such as at least
65% of the total cross sectional area of the elongated chamber 2, 20.
[0190] In some embodiments of the present disclosure, the cross sectional area of the elongated
insulation block (4, 40) takes up at least 60% of the total cross sectional area of
the elongated chamber 2, 20 over at least 70% of the length of the profile.
[0191] The one or more interior spaces S1, S2 provides a deflection space into which a part
BP1, BP2, 4W of the elongated insulation block 4, 40 extends in response to a compression
force subjected in a compression direction to the elongated insulation block 4, 40
inside the elongated chamber 2, 20.
[0192] In some embodiments of the present disclosure, the cross sectional area of the elongated
insulation block 4, 40 may take up between 50% and 90%, such as between 60% and 80%,
such as between 65% and 72% of the total cross sectional area of the elongated chamber
2, 20.
[0193] It is understood that the cross section of the profile may be determined (such as
in a plane) perpendicular to the longitudinal direction of the profile, and that the
cross section of the elongated insulation block may be determined (such as in a plane)
perpendicular to the longitudinal direction of the elongated insulation block.
[0194] In some embodiments, the compression direction CD is at least partly transverse to
the depth direction dd1, dd2 of the spaces (such as slits) S1, S2, so that one or
more wall side surfaces WS1, WS2 of the elongated insulation block 4, 40 that abuts
the at least one space S 1, S2 is/are moved into the space S1, S2. This is illustrated
in fig. 1 as well as in fig. 2.
[0195] In some embodiments of the present disclosure, the depth direction DD 1, DD2 may
extend along, such as parallel to, or with an acute angle to, an exterior major surface
12a, of the insulated glass unit. In case of an acute angle, acute angle, this acute
angle may be less than 30°, such as less than 20° or less than 10°
[0196] The partition wall part 4W, 40W of the elongated insulation block comprises a first
partition wall side surface WS1 and a second partition wall side surface WS2. The
partition wall side surfaces WS1, WS2 are oppositely directed so that a first of the
partition wall side surfaces WS1 faces a first of the spaces S1, and a second of the
partition wall side surfaces WS2 faces the other of the spaces, S2. In figs. 1-2,
the spaces S 1, S2 are slits. Each partition wall side surface WS1, WS2 extends in
the depth direction DDR1, DDR2 of the respective slit between the slit opening SO1,
SO2 in the respective outer surface 4a, 40a, 4b, 40b and the slit bottom SB1, SB2
that is provided by the bottom wall part 7.
[0197] As can be seen, one or both body parts BP1, BP2 may in embodiments of the present
disclosure comprise a surface BP1S, BP2S facing and abutting the respective slit/space
S1, S2.
[0198] In some embodiments of the present disclosure, one or both of the first and second
insulation body parts BP1, BP2 and/or the partition wall part 4W, 40W of the elongated
insulation block 4, 40 may be configured so as to rotate around a rotation axis RAX1,
RAX2 in response to the compression force provided by the profile 1. The rotation
axis RAX1, RAX2 extends in the longitudinal direction LD2 of the elongated insulation
block.
[0199] The two rotation axes RAX1, RAX2 are substantially parallel and are arranged at different
side portions of the elongated insulation block 4, 40.
[0200] The rotation may e.g. be provided by the partition wall 4W, 40W and/or walls 7 deflecting
in response to the compression force.
[0201] If more than two rotation axes are present, these may also be parallel, e.g. if more
than two slits S1, S2 are provided.
[0202] In some embodiments of the present disclosure, as illustrated in figs 1 and 2, said
rotation axis RAX1 RAX2 may be defined by and/or arranged at the area of the at least
one interconnecting wall part 7 and/or the partition wall 4W, 40W. This may help to
provide a flexible and controlled deformation of the insulation block 4, 40, so that
the orientation and displacement of the body part BP1 and/or BP2 is adapted the interior
geometry of the chambers 20, 2, that is defined by the profile 1 walls 3a-3e and/or
parts 8, 9 connected to or integrated therein.
[0203] Accordingly, rather than providing a compression of the outer portions of the body
parts BP1, BP2 near the profile wall, the compression of the elongated insulation
block 4, 40 is obtained in a controlled manner in the designed compression area of
the spaces S1, S2 and the partition wall.
[0204] In some embodiments of the present disclosure, the body parts BP1, BP2 may be substantially
solid in the sense that substantially no holes, gaps, openings, slits and/or the like
are provided other than air/gas pockets provided by inherent properties of the insulation
itself.
[0205] The maximum uncompressed height H1 of the elongated insulation block 4, 40 is reduced
to a reduced height H2 by of the profile 1 by means of compression, see fig. 2. This
compression may in embodiments of the present disclosure be at least 1%, such as at
by at least 3%, such as at least 5% or at least 10% when compared to the initial,
uncompressed height H1 of the elongated insulation block 4, 40. However, the compression
of the elongated insulation profile 1 is effectuated at the area of the spaces/slits
S 1, S2, so that the body parts BP1, BP2 are displaced into the spaces provided by
the slits S 1, S2, thereby preventing or at least reducing the compression of the
material of the bodies PB1, BP2.
[0206] In some embodiments of the present disclosure, the elongated insulation block 4,
40 is compressed H2 by no more than 15%, such as no more than 10%, such as no more
than 7% when compared to the initial, uncompressed US height H2 of the elongated insulation
block 4, 40.
[0207] The maximum (uncompressed) height H1 of the insulation block 4, 40 extends between
oppositely directed surfaces SU1, SU2 of the insulation block. The wall or walls 4W,
7 suspends the body parts BP1, BP2 from each other until an outer compression force
is applied in the compression direction CD. In some embodiments, the spaces S1, S2,
such as slits, are located with a distance from both of the oppositely directed surfaces
SU1, SU2 (see fig. 2), with a distance of at least 10%, such as at least 20% or at
least 30% of the uncompressed height H1 of the insulation block 4, 40, from one or
both of the respective surface SU1, SU2.
[0208] The depth direction DD1, DD2 may extend at least partly transverse to the height
H1, H2 direction.
[0209] In one or more embodiments of the present disclosure, the elongated insulation block
1 is a substantially monolithic structure/block. Hence, the elongated insulation block
1 may be molded, cut or in other ways shaped in a single-piece material. In other
embodiments of the present disclosure (not illustrated), however, the insulation block
1 may not be monolithic and may be shaped by two or more insulation parts, such as
made from or consisting of the same insulation material. In this case, these insulation
parts may be glued together, mechanically interconnected and/or the like in order
to provide an insulation block build from two or more interconnected insulation parts.
[0210] In one or more embodiments the present disclosure, the elongated insulation block
1 is without interior reinforcements, such as substantially without interior reinforcements
of another material and/or density than the insulation material of the elongated insulation
block 4, 40. Hence, the density of the insulation block 1 material may be the same
for substantially the entire insulation block.
[0211] The interior spaces S 1, S2, such as slits, are elongated and extend in the longitudinal
direction of the insulation block. The interior, elongated spaces S1, S2, such as
slits, is/are pre-shaped in the elongated insulation block and is/are provided at
predefined locations of the elongated insulation block 4, 40.
[0212] In some embodiments of the present disclosure, the interior, elongated spaces S1,
S2, such as slits are provided as a result of a manufacturing solution involving one
or more of:
- machining the one or more interior spaces S 1, S2, such as slits, into the elongated
insulation block,
- melting the one or more interior spaces S1, S2, such as slits, into the elongated
insulation block, and/or
- molding extruding and/or pressing the elongated insulation block during insulation
block shaping/manufacturing so as to provide an elongated insulation block comprising
the one or more interior spaces S 1, S2.
[0213] As can be seen from fig. 1, the elongated insulation block 4, 40 may in embodiments
of the present disclosure rest one or more elongated protrusions 8, 9 such as ridges.
[0214] In fig. 1, two types of such protrusions/ridges 8, 9 are illustrated. The first protrusion
type is a reinforcement protrusion 9. The reinforcement protrusion(s) 9 are configured
to reinforce the profile 1 to improve the structural integrity.
[0215] In some embodiments of the present disclosure (not illustrated), the reinforcement
protrusion 9 may comprise an elongated, solid protrusion made substantially entirely
from the same material as the wall 3a-3f wall material and extending in the longitudinal
direction of the profile 1.
[0216] In the embodiment of fig. 1, the reinforcement protrusions 9 extend in the longitudinal
direction of the profile 1, and a reinforcing core 9a, such as a metal core, e.g.,
a metal rod, such as a solid metal rod, is embedded inside the protrusion 9. In other
embodiments, the reinforcing core 9a may be a material different from the profile
wall 3a-3e material, and may e.g. be harder than the wall material. For example, a
harder polymer material and/or a fiber reinforced material. This may e.g. be provided
by means of co-extrusion. The cross section of the reinforcing core 9a may e.g. be
rectangular (as illustrated), or it may e.g. be circular or have another polygonal
shape (not illustrated). The reinforcing core 9a may as illustrated be surrounded
by, and may abut, a shell of the same material as the walls 3a-3e.
[0217] In fig. 1, five reinforcement protrusions 9 are provided, but it is understood that
fewer, such as two, three or four reinforcement protrusions 9, or more than five,
such as six, seven or eight reinforcement protrusions 9, may be provided in further
embodiments. In fig. 1, two of the reinforcement protrusions 9 are placed opposite
to the glass unit side surface 12e, and three reinforcement protrusions 9 are arranged
at the side PS1 of the glass unit plane PL1 facing away from the major glass unit
surface 12a. The major glass unit surface 12a is intended for facing the interior
of the building after window (or door) installation. The plane side PS1 faces the
wall 3c1 that supports the glass unit and the gasket 11. The major glass unit surface
12a comprises/defines the plane PL1. In the embodiment of fig. 1, the major surface
12a is provided by means of the lamination glass 12_4 surface (the surface may be
coated or uncoated).
[0218] The reinforcement protrusions 9 are discreetly arranged with a distance between neighboring
reinforcement protrusions. The reinforcement protrusions 9 may be parallel.
[0219] In some embodiments of the present disclosure, an air gap AG of at least 1 mm, such
as at least 2 mm is provided between the elongated insulation block 4, 40 and one
or more of the exterior profile walls 3a-3e. In some embodiments of the present disclosure,
an air gap AG of between least 1 mm and 5 mm, such as between 2 mm and 5 mm, is provided
between the elongated insulation block 4, 40 and one or more of the exterior profile
walls 3a-3e. In some embodiments, the air gap AG height may substantially correspond
to the height of the reinforcement protrusion 9 height.
[0220] As illustrated, the air gap AG may be placed next to one or more of said protrusions
9, such as between the protrusions 9.
[0221] However, also larger, straight surfaces facing the interior chamber of the profile
may not be in touch with, or may only be partly in touch with the insulation block.
For example, in some embodiments, the profile wall 3b for facing the frame opening
FO of the final window or door frame may comprise a wall surface facing the interior
chamber 2, where that wall surface that is not in touch with, or is only partly in
touch with the insulation block. This is illustrated in e.g. fig. 1. As can be seen,
the air gap AG distance between the insulation block 4 and the wall 3b may gradually
increase from the distant profile corner B and towards the corner C that is placed
proximate the major surface 12a of the insulated/insulating glass unit 12.
[0222] The insulation block 1 may in embodiments of the present disclosure, as illustrated,
not extend into the air gap(s) AG. Instead, it may rest on top of the protrusions
9, 8.
[0223] The other type of protrusion is protrusion 8 provided to obtain a recessed portion
in the exterior surface of the profile 1, such as the recessed portion in the wall
3c1. The recessed portion in wall 3c 1 is provided in order to receive a part of a
gasket 11 that is placed between the profile wall 3c1 and the glass unit 12. The recessed
portion may e.g. be provided to maintain the gasket 11 in place and/or help to provide
space for a gasket material to enable improved characteristics, such as improved resiliency
and/or tightness of the gasket 11 and/or to enable a smaller distance between the
profile wall 3c 1 and the glass unit.
[0224] The elongated protrusions 8, 9 extends in the longitudinal direction LD1 of the profile
1.
[0225] The elongated protrusions 8, 9 provides a compression of the elongated insulation
block 4, 40.
[0226] In some embodiments of the present disclosure, the elongated insulation block 4,
40 may be un-bonded to the profile 1.
[0227] Computer simulations have shown that even though one or more interior, elongated
spaces S1, S2 (in the simulated example it was slits) is/are provided in the insulation
material, the heat insulation performance may still be acceptable, and a U-frame value
lower than 1.54 W/mK, such as lower than 1.52 W/mK, such as lower than 1.51 W/mK may
be obtained after insulation insertion. This may even be obtained while at the same
time leaving certain areas AG of the elongated chamber 2 unfilled with insulation
material of the insulation block.
[0228] In fig. 1, the window or door profile 1 comprises a first 2 and a second 20 elongated
chamber. A first 4 and a second 40 of said elongated insulation block 1 is provided
in each their chamber 2, 20. The first insulation block 4 is arranged to extend in
over and overlap the major surface 12a of the glass unit. The first insulation block
4 also extends in a direction parallel to the major surface 12a to a position out
over the side edge of the glass unit 12. Hence, as can be seen, a part of the first
insulation block 4 extends to a position opposite to, in this case below, the major
surface 12a of the glass unit 12.
[0229] The first insulation block 4 is arranged opposite to the support wall 3c1 of the
profile which is configured to support the major glass unit 12 surface 12a.
[0230] The second insulation block 40 is arranged so that it overlaps the side edge 12e
surface.
[0231] The second insulation block 40 is arranged opposite to the profile wall 3c2.
[0232] As can be seen from fig 1, the first insulation block 4 and second insulation block
40 may I embodiments of the present disclosure overlap. As can be seen, the second
insulation block 40 may extend through the plane PL1.
[0233] In embodiments of the present disclosure, the first insulation block 4 and second
insulation block 40 overlaps in a direction parallel to a major surfaces 12a and 12b
of the glass unit. Additionally (as illustrated) or alternatively, the first insulation
block 4 and second insulation block 40 may overlap in a direction perpendicular to
the major surfaces 12a and 12b of the glass unit. In the embodiment illustrated in
fig. 1.
[0234] One or both insulation blocks 4, 40 may as illustrated comprise slanting surfaces.
In fig 1, the slanting surfaces face the partition wall 1w of the profile. The slanting
surfaces may, or may not, about the partition wall 1w.
[0235] In some embodiments of the present disclosure, one or both of the insulation blocks
4, 40 may comprise one or more of the spaces S1, S2, such as slits, as described according
to various embodiments of the present disclosure above and/or below. In other embodiments
of the present disclosure, only one of the insulation blocks 4, 40 may comprise one
or more of the spaces S1, S2, such as slits. In some embodiments, for example, the
second insulation block 40 may be omitted or another insulation solution may be provided
in the cavity 20.
[0236] In figs. 1 and 2, one or more of the bottom walls 7 and/or the partition wall 4W
is/are in a deflected state when the insulation block 4 is in the compressed state
CS.
[0237] It is generally understood that in embodiments of the present disclosure, the elongated
insulation block 4, 40 may be compressed inside the profile so that the height H1
of the elongated insulation block 4, 40 is reduced, see H2, whereas the insulation
block 4, 40 may remain substantially uncompressed in the width direction WD of the
profile.
[0238] Fig. 3 illustrates schematically the insulation block 4 according to embodiments
of the present disclosure, seen in perspective. In fig. 3, the interior spaces S1,
S2, in this case slits, extends continuously in the longitudinal direction LD2 of
the elongated insulation block 4, 40 between the opposite ends E1, E1_1 of the elongated
insulation block 40. The elongated insulation block 40 has a length IBL extending
in the longitudinal direction. This length may extend over substantially the entire
length of the profile 1.
[0239] Fig. 4 illustrates schematically an end part of the second insulation block 40, seen
in perspective. This 40 has a longitudinal direction LD2 and may have a length substantially
corresponding to the length of the profile 1 and/or the length of the first insulation
block. Also here, the spaces S1, S2 are slits arranged in oppositely directed surfaces.
[0240] As can be seen from figs 1 and 4, the cross section of the body part B2 may be substantially
larger than the cross section of the body part BP1, such as more than 1.5 times or
more than 2 times larger the cross section of the body part BP1.
[0241] Fig. 5 illustrates schematically the insulation block 4, seen from the side, towards
the side surface 4a comprising the slit S1. Also here, it can be seen that the slit
S1 may extend continuously between the opposing ends E1, E1_2. This is different from
the embodiment illustrated in fig. 6.
[0242] Fig. 6 illustrates schematically an embodiment of the present disclosure, wherein
the insulation block 4 (and/or 40) comprises a plurality of discrete, consecutively
arranged, interior spaces S1, S2, in this case slits. The view is towards the surface
4a, but it is understood that the second slit S2 may also be present, as illustrated
by dashed lines in fig. 5 and 6.
[0243] In fig. 6, as opposed to fig. 5, the slits comprises a plurality of slits S1, S2
that are distributed consecutively between the opposite ends E1, E1_1 of the elongated
insulation block 4, 40, The consecutively arranged, slits S1, S2 are separated by
intermediate, discrete walls 14 of insulation material that are distributed in the
longitudinal direction of the insulation block 1, and acts as partition walls between
two neighboring slits so that a plurality of slit openings SO1 are provided. These
intermediate walls 14 between neighboring slits provides a certain resistance towards
compression of the insulation block 1, and may help to provide a counter force when
the insulation block is subjected to a compression force in the compression direction
that is transverse to the longitudinal direction of the insulation block 4. It is
understood that the thickness of the walls 14 may be relatively low so as to allow
the walls 14 to buckle and/or in ither ways deform in response to the compression
force in the compression direction CD that is subjected by the profile 1,so that the
body part(s) BP1, BP2 moves into the slit spaces and to reduce or avoid compression
of the insulation material of the body part(s) BP1, BP2.
[0244] The thickness of the walls 14 (i.e. the wall thickness extending in the longitudinal
direction LD2 of the block 1) may in embodiments of the present disclosure be at least
10 times, such as 20 times, such as at least 40 times, smaller than the length of
one or both neighboring slits S1 that abuts the respective, intermediate wall 14.
[0245] Figs. 7-10 illustrate schematically various embodiments of the elongated insulation
block 4, 40 and the interior spaces S1-S3 (in these embodiments slits) thereof, according
to various embodiments of the present disclosure.
[0246] In fig. 7, and also the various embodiments shown in e.g. figs. 1-10, the compression
direction CD is at least partly transverse to the depth direction dd1, dd2 of the
spaces S1, S2, in this case slits. The slits S1, S2 have a depth (see fig 2) which
extends in a depth direction DD1, DD2 transverse to the longitudinal direction of
the elongated insulation block 4, 40. Also, the depth of the slits S1, S2 extends
transverse to the compression direction CD. The slits S1, S2 extends from a slit opening
SO1, SO2 in a surface 4a, 4b of the insulation block 4, 40.
[0247] In figs. 1 and 2, the depth direction DD1, DD2 of the slits (in an uncompressed state)
extends substantially perpendicular to height H1 direction HD of the insulation block
1 and may be parallel to the width direction WD (in an uncompressed state), whereas
in figs. 7 and 10, the depth directions DD1, DD2 extends sloping with respect to the
height direction HD and width direction WD of the insulation block 1.
[0248] The depth directions DD1, DD2 may in embodiments of the present disclosure be parallel
and oppositely directed (See e.g. figs. 2-4 and 7-9). In other embodiments, the depth
directions DD1, DD2 may be at least partly oppositely directed and non-parallel, See
fig. 10. For example, in embodiments of the present disclosure, the mutual angle a1
between the depth directions DD1, DD2 may in embodiments of the present disclosure
be between 1° and 30°, such as between 3° and 20°, such as between 8° and 15°. The
angle a1 may in embodiments of the present disclosure be an acute angle.
[0249] Figs. 8 and 9 illustrate further embodiments of the present disclosure. Here three
spaces S1-S3 are provided, and in this embodiment, the spaces S1, S2, S3 are slits.
These slits are provided so that the elongated insulation block is Sigma-shaped (Σ-shaped)
when seen in cross section in a plane that is perpendicular to the longitudinal direction
LD2 of the elongated insulation block 4, 40. The slits S1-S3 are separated by partition
walls W1. One or more, or all, of the slits S1-S3 illustrated in figs. 7-10 may extend
continuously (see figs. 3-5) between the oppositely directed ends of the insulation
block 1. In other embodiments, one, more or all of the slits S1-S3 may comprise consecutively
arranged slits that are separated by intermediate walls 14 which are discretely arranged/distributed
in the longitudinal direction of the insulation block 1. See fig. 6 and the description
thereto.
[0250] As illustrated in e.g. figs 1-4 and 7-10, the slits S1-S3 may provide a corrugated
deflection portion of the insulation block, e.g. by providing An S-shape or is Sigma-shaped
(Σ-shaped) cross section. Here it may be understood that the slits S1, S2 and/or S3
provide the grooves/channels and the walls 7 provides the ridges of the corrugated
shape.
[0251] Figs. 11-13 illustrate schematically a method of providing an insulated window or
door profile 1, according to embodiments of the present disclosure, where an insulation
block is introduced into a chamber of a profile 1. The obtained, insulated profile
may be a profile as e.g. described above and/or below.
[0252] The window or door profile 1 comprising exterior walls 3a-3e is provided. The profile
1 may e.g. be a profile 1 having a cross sections with walls 3a-3f and possibly also
one or more partition walls 1w as previously described. See e.g. fig. 1.
[0253] An elongated insulation block 4, 40 is provided. This insulation block may e.g. be
