Abstract
A glass fiber mat comprises glass fibers of a first kind, glass fibers of a second kind and a binding agent. Glass fibers of the first kind in this case are characterized by a mean fiber diameter of under 6 μm and compliance with the EC Protocol “ECB/TM/27 rev. 7” and glass fibers of the second kind by a mean fiber diameter of over 6 μm. The ratio between the weight component of glass fibers of the first kind and the weight component of glass fibers of the second kind is between 0.01 and 0.15. And the surface weight of the glass fiber mat is between 25 g/m2 and 80 g/m2. In a CV floor covering comprising a usable layer and a structural layer, the structural layer comprises a glass fiber mat of this kind provided with impregnation.
