CV floor coverings (CV = cushioned vinyls) consist of a foamed PVC layer with printed décor and a transparent wear layer on top. The material thickness is usually approx. 2.5 – 3.7 mm. The foaming causes a significant improvement in impact sound reduction of up to 19 dB (for comparison: a conventional PVC floor achieves approx. 5 dB impact sound reduction). They are therefore particularly suitable for recreation and work areas with increased impact sound requirements or if an existing substrate, e.g. a composite screed, does not have sufficient impact sound-reducing properties.
