Heat insulating plate as a foundation for a concrete cladding, especially in multilayer fire resistant constructions

摘要

The polymer film (2) is 100-500 microns thick and is applied to the inner side (1) facing the concrete cladding where it acts as barrier layer (3) to prevent penetration of water from the wet concrete into the porous foundation plate (1K). A 100 - 500 microns thick polymer film (2) is applied to the inner side (I) facing the concrete cladding where it acts as barrier layer (3) to prevent penetration of water from the wet concrete into the porous foundation plate (1K). The polymer film (2) is 100-500 microns thick and is applied to the inner side (I) facing the concrete cladding where it acts as barrier layer (3) to prevent penetration of water from the wet concrete into the porous foundation plate (1K). Independent claims are made for: (a) a method for manufacturing a foundation layer based on a porous water absorbing mineral material and used in a heat insulating plate; and (b) a use of the heat insulating plate in fire resistant constructions.
