Abstract
Abstract A wall covering material comprising a front, decorative filled cover layer containing textile fibers and a rear foam plastic layer. The foam plastic layer contains flame-retarding additives, is elastic and gas pervious. Furthermore, it contains closed cell inorganic hollow spheres or small balls, which rigidify or stiffen the foam plastic layer, but do not unduly impair its restoring capability and also do not impair the insulation capability, sound absorption capability and flame resistance.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
140 words
A wall covering material for covering a structure, such as a wall, comprising: a fiber containing cover layer provided at a front face of the wall covering material, which, during use, confronts the viewer; an elastic, gas pervious foam plastic layer provided at a rear face of the wall covering material which, during use, confronts the wall; said foam plastic layer containing a foam plastic material comprising an open cell foam of a vulcanized product containing styrene-butadiene-rubber, and possesses a high restoring capability following deformation; said foam plastic layer containing flame-retarding additives including hollow spherical-like granules formed of an inorganic material having closed cells which at least for the most part are filled with an inert gas; and said foam plastic layer containing the additives and said cover layer defining a composite possessing heat insulation, sound absorbing and flame-retarding properties.
Claim 2
Dependent Claim
