Title:
INSULATION ELEMENT FOR THERMAL AND/OR ACOUSTIC INSULATION OF A FLAT OR FLAT INCLINED ROOF AND METHOD FOR PRODUCING AN INSULATION ELEMENT
Document Type and Number:
WIPO Patent Application WO/2020/201449
Kind Code:
A3
Abstract:
Insulation element (4) for thermal and/or acoustic insulation of a flat roof (1), comprising a first layer (5) made of mineral wool and a second layer (6) made of at least one fabric, whereby the second layer (6) is fixed to a major surface (7) of the first layer (5) by an adhesive (9), whereby the first layer (5) is made of at least one lamella having a fiber orientation predominantly perpendicular to major surfaces (8) of the second layer (6), whereby the first layer (5) contains a cured binder whereby the adhesive (9) is arranged partly in an area (10) between fibers close to the major surface (7) of the first layer (5) directed to the second layer (8) and in an area (11) close to the major surface (8) of the second layer (8) directed to the first layer (5) so that the adhesive (9) connects the first layer (5) and the second layer (6) in such a way that forces directed perpendicular to the second layer (6) can be compensated by the tensile strength of the second layer (8) in combination with the adhesive (9) and/or the deflection of the fibers of the first layer (5) causing a maximum deformation of < 5 % of the thickness of the first and second layer (5).
