Multi-layer structural building material and its use.

摘要

A multilayer structural building material comprises a polyolefin or polybutadiene foam sheet as a base layer (1), a a dry coated layer of a polychloroprene-type adhesive as an interlayer (2), and a dry coated layer of a mixture of a water-base adhesive and an inorganic filler as a surface layer (3). This material finds use as a backing material, to provide an insulating or cushioning effect, on walls, ceilings or floors for surface materials such as wallpapers or non-woven fabrics.
