(57) It is a prefabricated insulating perlite slab of reverse insulation having as its
principal ingredient, the expanded perlite whose manufacturing principle has been
invented in order to cancel the weaknesses of the conventional perlite insulation
and which is used for the insulation (heat-insulation and sealing ) of normal accessibility
terraces and slopping roofs of buildings, with reversed perlite insulation (with reversed
insulation, with permeability) for healthy living conditions.
Its construction know-how, transforms the unified water-absorbing heat-insulating
layer of the conventional insulation, into small water-absorbing heat-insulating layers
(1) which are sealed between them, with the reinforced concrete slab (3) of the terrace,
with the balustrade of the terrace and with the external environment, having as result,
the protection of the heat-insulation (the success of the insulation).
It is water tightening, heat-insulating and simultaneously sealing, while its mass
is water absorbant.
It has a light weight (it does not affect the anti-seismicity of the building), it
is practicable, heat-insulating, permeable (it respires) and fire-resistant.
It is manufactured in 4 types, A, B, C/Γ and D.
