A glass fibre mat comprises glass fibres of a first kind, glass fibres of a second kind and a binding agent. Glass fibres of the first kind in this case are characterized by a mean fibre diameter of under 6 mum and compliance with the EC Protocol "ECB/TM/27 rev. 7" and glass fibres of the second kind by a mean fibre diameter of over 6 mum. The ratio between the weight component of glass fibres of the first kind and the weight component of glass fibres of the second kind is between 0.01 and 0.15. And the surface weight of the glass fibre 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 fibre mat of this kind provided with impregnation. |
