[0001] This invention regards a counter-frame structure for a window, a French window or
a skylight to be inserted in an opening in a wall or roof, separating the interior
and exterior of a building.
[0002] With view to optimising the building's heat insulation the frames are made with special
attention to the selection of materials, inserting suitable insulation materials into
the sections comprising the frames, for example a polystyrene or a polyurethane foam,
and/or envisaging appropriate gaskets between the mobile and fixed parts of the frames.
In this way it is sought to increase the frame's thermal cut-off and thus increase
its insulation coefficient.
[0003] However it is well known that there are considerable thermal bridges - hence sources
of heat dispersion - at other points of the frame, in particular with regard to the
counter-frame, i.e. in the zone of anchorage of the counter-frame to the wall, the
sills, the box shutter etc.
[0004] Reducing these thermal bridges results in a considerable increase in the overall
insulation coefficient of the frame.
[0005] The attempt to limit this heat dispersion has, to date, been limited to connecting
any external protective skin of the building's wall to the door or window frame. This
however calls for considerable modification of the wall and requires the presence
of the architect and building contractor, with a consequent increase in installation
time and costs.
[0006] FR-A-2 539 801 discloses a prefabricated element suitable to be fitted into an opening of a wall
for forming a decorative covering for the opening and making it possible to receive
the framework of the corresponding doors or windows. The prefabricated element may
be filled with a thermal insulating material.
[0007] DE 299 05 365 U1 discloses a pre-finished heat insulating element for the inner edge of a wall with
an opening, e.g. for doors and windows.
[0008] EP-A-1 455 027 discloses a heat insulation kit applied externally to a cellar ventilation window
to prevent the formation of a heat bridge between the cellar wall and the light shaft.
[0009] DE 20 2006 004425 U1 discloses a framework assembly including a door frame, window sash and a damming
system, resting against the frame work assembly, formed according to building material
class A1 or A2.
[0010] EP-A-1 172 495 discloses a thermal insulation of the surround frame of a building opening, comprising
at least two first heat insulating elements for arranging above and below the building
opening, and at least two second heat insulating elements for arranging next to the
first elements and lateral to the building opening.
[0011] The purpose of this invention is to propose a counter-frame structure that gives
the entire frame system greater thermal efficiency while at the same time obviating
the installation drawbacks mentioned above.
[0012] Such purpose is achieved with a counter-frame structure according to claim 1. The
dependent claims describe preferred embodiments of the counter-frame. In brief, one
innovative feature common to all the embodiments of the proposed counter-frame structure
is the fact that it is created as a single block comprising a counter-frame and an
insulating surround, ready for installation in the opening of a wall or roof and such
as to obtain immediate and optimal heat insulation without the need for further intervention.
[0013] The other functional elements of the frame structure, such as the frame itself with
accessories and blinds, can be assembled at the time of installation since the structure
is adaptable to any type of frame and blind or - most favourably - can be supplied
to the building contractor already mounted on the structure.
[0014] In particular, it is extremely advantageous to be able to supply the builder with
a single block, already cement rendered (or pre-rendered) and equipped, in the case
of windows, with sills. In this way building intervention on the frame is reduced
to a minimum.
[0015] It should moreover be underscored that the structure is suitable for installation
in any kind of wall with any thickness whatever of external protection.
[0016] In particular, the structure is conceived for mounting prior to application of the
insulating skin, taking into account the thickness thereof in such a way that subsequently
any discontinuity between frame and wall can be eliminated. Insulation of inclined
external surfaces or reveals can be carried out at various angulations.
[0017] In any case, the structure in accordance with the invention reduces, if it does not
eliminate, the thermal bridges still found in state of the art frames, in particular
between wall and counter-frame, between wall and reveals insulation and between wall
and skin, all of this without burdensome building work. In other words, once installed
the frame is already completely insulated.
[0018] The structure is conceived in such a way that various types and sizes of insulation
may be used, e.g. up to 400 mm thickness.
[0019] A further advantage is that the customer can deal with one single supplier for counter-frame,
frame insulation, blinds and internal/external sills.
[0020] Lastly, it should be noted that the counter-frame structure is applicable to frames
in any material whatsoever, e.g. wood, aluminium, PVC or combinations thereof, and
can be used in various types of buildings such as prefabs, traditional buildings in
masonry and concrete and also in renovations.
[0021] For a better understanding of the invention and appreciation of its advantages, some

[0038] figure 16 is a horizontal section view of the frame structure in figure 15.
[0039] With reference to the figures (where equivalent elements are indicated with the same
numerical references), in accordance with a general embodiment, the counter-frame
structure of the present invention comprises a counter-frame 10 for door and window
frames and an insulating surround 12, in heat insulation material, which surrounds
counter-frame 10 at least on the sides facing wall 5 in which it is to be placed and
facing the exterior of the said wall. Counter-frame 10 and insulating surround 12
are connected in such a way as to form a single block 1; 2 to be inserted in an opening
in wall 5.
[0040] An example of heat insulation material is a thermoplastic polymeric material, in
particular a polystyrene.
[0041] In accordance with one embodiment, the insulating surround 12 is of such thickness
as to extend between internal side 5' and external side 5" of wall 5 in which the
structure is inserted. As will be better exemplified below, such a thickness of insulating
surround 12 permits, in the upper part, incorporation of a recess or other containing
and guiding devices for the blind elements 42,48 of the frame and, in the lower part,
the creation of a support base for the internal 22 and external window sills 23.
[0042] It should be noted that in the examples illustrated the counter-frame structure is
suitable for insertion in a wall 5 consisting of a part in masonry 6 and an external
protective facing known as "skin" 7. Most favourably, the insulating surround 12 extends
frontally to the level of skin 7 in such a way as to create a continuous insulation
between the heat insulation material of the surround 12 and that of skin 7.
[0043] To this end surround 12 comprises a frontal portion 7a with the same thickness and
in the same material as skin 7, and a rear portion 6a, also in insulating material,
corresponding to the thickness of the masonry part 6. In this way, whatever the sizes
of the space in the wall 5 and of the counter-frame 10, thanks to the perimeter insulation
parts 6a and 7a the counter-frame structure can be adapted to the size of the space
and therefore inserted in the wall 5 with extreme precision, connecting it up with
insulating materials to the elements comprising the wall 5 itself.
[0044] Most favourably, the internal and external surfaces of insulating surround 12, meaning
those facing the interior 5' and exterior 5" of the building, are covered with a layer
of rendering 14 which extends to conceal counter-frame 10. In other words, the rendering
operation, usually carried out with the counter-frame 10 installed, takes place at
building phase, thus avoiding soiling or damaging the counter-frame 10 at the door/window
installation phase.
[0045] More precisely, on the surface facing the exterior 5" a pre-rendering operation is
carried out in such a way that, having mounted the counter-frame 10, the builders
then carry out a final rendering that connects the external surface of the counter-frame
structure with the wall 5 of the building.
[0046] In accordance with one embodiment, the coat of rendering 14 or pre-rendering is laid
on scrim or template 16 which covers the internal and external surfaces of insulating
surround 12.
[0047] In accordance with a favoured embodiment, insulating surround 12 is profiled in such
a way as to define at least one housing 18 for a blind element 42,48 (as will be better
specified below in the description of examples of implementation).
[0048] Moreover, the insulating surround 12 integrates, or is equipped to integrate, at
least certain functional elements of the door/window-frame 32 such as guides for sliding
parts 44,49 and sealing elements against water or dust.
[0049] Most favourably, the guides 44,49 for rolling or sliding elements are created in
insulating surround 12 at a distance from the elements of counter-frame 10 in such
a way as to interpose layer 12" of heat insulation material. This results in avoiding
or reducing the effect of any thermal bridge that would be created by contact between
the said guides and counter-frame 10.
[0050] In the case of a counter-frame 10 for a window, the insulating surround 12 includes
a base element 20 which can be covered by at least one plate in such a way as to create
internal sill 22 and/or external sill 23 of the window-frame 32.
[0051] In accordance with one embodiment, the insulating surround 12 extends in such a way
as to at least partially overlap frame 30 which is fixed, or will be fixed upon installation,
to counter-frame 10. At least partial overlapping is understood as being at least
from the part facing the exterior 5". In fact in this way the external side of frame
30 is covered by insulating surround 12 and therefore benefits from greater thermal
protection. Having thus limited cooling of the exposed surface of frame 30, heat dispersion
from interior 5' to exterior 5" by way of the frame 30 is therefore avoided right
from the start.
[0052] According to one embodiment, the insulating surround 12 actually extends also to
overlap the opening window-frame 32 in such a way that only the glazed part is visible
from outside. In this case, over and above the aesthetic result, external surface
cooling of both frame 30 and opening window-frame 32 is avoided, thus reducing overall
heat dispersion.
[0053] Given that especially in the cases described above - in which insulating surround
12 overlaps the frame 30 and the opening window-frame 32 - parts of the upright 10"
and parts of the upper lower horizontal sides 10' of insulating surround 12 in practice
visually delimit the opening in the wall 5, these parts may be advantageously faced
with the respective profiles 34, for example U-shaped and also including angle-joints
in metal or plastic material, thus giving a pleasing aesthetic effect.
[0054] Furthermore, the use of a surround 12 in heat-insulation material that extends to
the external surface 5" of the wall 5, with the possibility of easily forming the
surround elements according to taste, means that the frame structure can be connected
to the said external surface 5' with special lines, for example with inclined surfaces
36 that open towards the exterior. This among other things means maximising the entry
of light through the door/window-frame, especially when the surround 12 overlaps the
frame. It should be noted that to date the same result has been sought by breaking
the wall 5 or the external protective skin 7, with considerable negative consequences
in terms of time and costs.
[0055] In accordance with one embodiment, insulating surround 12 is formed by a plurality
of elements 12', for example in the form of square bars or blocks, closely coupled
in such a way as to leave no interstices through which heat could be propagated.
[0056] These elements 12' of surround 12 are coupled by means of flat and extended contact
surfaces or, even more favourably, are linked with a geometrical or jointed coupling.
[0057] In any case, at least some of the elements 12' of surround 12 are fixed to counter-frame
10 of the door/window-frame. In accordance with preferred embodiments, said elements
12' of surround 12 are fixed to the counter-frame 10 by gluing and/or by screwing
and/or by means of clamps or profiled sheet metal.
[0058] In particular, and most favourably, the upper and lower horizontal sides 10' and
vertical sides or uprights 10", that define the sides of counter-frame 10, and the
adjacent elements of surround 12, are profiled to be coupled geometrically or by a
joint. For example, the said sides 10', 10" of counter-frame 10 have a longitudinal
channel 11 in which a corresponding longitudinal projection 13 of the surround elements
is inserted.
[0059] Figures 1 and 2 illustrate two counter-frame structures of a window and a French
window respectively, in accordance with the invention, seen from the interior. The
said figures show the counter-frame 10 (including upper and lower horizontal sides
10' and vertical sides or uprights 10") with the insulating surround 12, formed by
elements 12', 20. Moreover there is also a box 40 for a roller blind 42 (figures 3
and 4), also inserted in surround 12 and, in figure 1, an internal sill 22.
[0060] The latter rests on the base element 20 of surround 12.
[0061] In the embodiment of counter-frame structure 2 for French window (figures 2 and 5)
no base element 20 is provided as support for sills 22, 23, but the surround 12 terminates
in any case with a lower horizontal bar 20' suitable for setting into the floor to
prevent the passage of heat from the lower part of the frame. To this end it should
be noted that lateral elements 12' of insulating surround 12 extend in the lower part
to the level of the lower extremity of bar 20'.
[0062] Most favourably, therefore, in the case of both window and French window, the whole
perimeter of counter-frame 10 is surrounded and enveloped by insulating surround 12.
[0063] Figures 3 and 4 illustrate a vertical section of counter-frame structure 1 for a
window, before and after fixing of the actual door/window-frame 30, 32 to counter-frame
10. The internal and external sills 22 and 23 can be seen resting on base element
20. The upper horizontal element 12' of surround 12 has, frontally, towards the exterior
of the door/window-frame, a box structure suitable for delimiting housing 18 for a
box 40 containing a roller blind element 42. It may moreover be seen that insulating
surround 12 comprises, as well as the upper element mentioned above that rests on
the jamb of the counter-frame 10, a further profiled section indicated as 12a which
covers the frontal side of counter-frame 10 and also extends to overlap frame 30.
As mentioned previously, profile 12a of surround 12 and the upper horizontal side
10' of the counter-frame 10 are coupled geometrically with a male (longitudinal projection
13)-female (longitudinal channel 11) type joint. An analogous arrangement of the elements
of the counter-frame 10 and the insulating surround 12 are found in the lower part
of the counter-frame structure. Figures 3 and 4 moreover show guide 44 for movement
of roller blind element 42.
[0064] Figure 5 moreover shows a horizontal element 10a for fixing surround 12 to counter-frame
10. This horizontal element 10a, for example a wooden bar, is sunk into upper transversal
element 12' of surround 12 to connect the latter, e.g. by means of screws, to the
lower horizontal side 10' of counter-frame 10.
[0065] In the horizontal sections of figures 6 and 7, with regard to counter-frame for a
window and the counter-frame for a window/French window combination, it is possible
to note the side profiles 12' of surround 12 that accompany uprights 10" of the counter-frame
10. Note the presence of inclined surfaces 36 obtained in the said profiles. In these
figures it can moreover be observed how guide 44 for blind element 42 is part of the
side profiles 12' and distanced from the counter-frame 10, with the interposition
of a layer 12" of heat insulation material.
[0066] Figures 8 and 9 illustrate a simpler counter-frame structure for a window, e.g. for
a window with shutters, therefore without an integrated blind element. In this case,
the upper part of surround 12 is limited to profile 12a which is joint-coupled frontally
with upper horizontal side 10' of counter-frame 10. Note in figure 9 the presence
of a pair of vertical bars 46 set in insulating profiles 12', e.g. in the same material
as counter-frame 10, which serve as supports for the shutter hinges.
[0067] Moreover, note how horizontal element 12a of surround 12 partially covers window
frame 30 while vertical elements 12' of surround 12, which are joint-coupled with
uprights 10" of the counter-frame 10, completely cover frame 30.
[0068] Figure 10 is a vertical section view of a counter-frame structure for a window with
an adjustable slats blind device 48. Apart from the different blind element the structure
of the counter-frame block-insulating surround is substantially the same as that of
figures 3 and 4.
[0069] Figure 11 illustrates a counter-frame structure analogous to the previous one but
for a French window. The lower part of the structure features a lower bar 20' of the
surround 12, set in the floor and in any case fixed to counter-frame 10.
[0070] In the corresponding view in horizontal section of figure 12, note how also in this
case guide 49 for the adjustable slats is obtained in the centre of side profiles
12' of surround 12, well spaced from counter-frame 10. Also note in this case the
presence of insulating perimeter elements 6a and 7a of the wall connection which is
fixed, e.g. by gluing, to counter-frame 10 and vertical uprights 12' of surround 12.
Said vertical uprights 12' of surround 12 completely cover window frame 30 and are
joint-coupled to vertical uprights 10" of counter-frame 10.
[0071] Figure 13 is a vertical section view of counter-frame structure for a sliding French
window without blind. Note lower bar 20' set in the floor and fixed to lower horizontal
side 10' of counter-frame 10. In the upper part insulating surround 12 includes the
wall connection elements and a frontal crosspiece that partially covers the sliding
frame, joint-coupled to upper horizontal side 10' of counter-frame 10.
[0072] Figure 13a, again referring to a counter-frame structure for sliding doors, differs
from the previous one inasmuch as we have housing 18 for a blind element. Note how
housing 18 is obtained from the bringing together of frontal profile 12a, which in
this case extends below to a greater extent, completely protecting the window frame,
with an upper horizontal profile 12' and thus creating the necessary thickness to
obtain housing 18.
[0073] The horizontal section of figure 14 shows two side insulation profiles 12' which
also integrate guide 49 for the blind element and further vertical insulation profiles
12b that fill the empty space between frame and sliding door.
[0074] Figures 15 and 16 concern a further example of application of the invention. More
precisely a counter-frame structure for a window with fixed glazing 50, which can
be shaded with adjustable slats element 48, of which it can be noted the housing 18,
provided in the upper part of insulating surround 12, and sliding guides 49 integrated
in vertical insulation profiles. Most favourably, the glazing 50 is directly fixed
to counter-frame 10, completely enclosed by insulating surround 12. Also at the level
of the vertical uprights of the structure, surround 12 extends both forward and rearward
with regard to counter-frame 10.
[0075] So from the exterior and the interior only glazing 50 is visible.
