RWS (%) - Footstep noise - The footstep noise is the sound created by the use of the floor, as perceived by the user in the same room. The flooring underlay has a structure that exhibits vibration absorption and damping properties. It also improves room acoustics by reducing reverberation.
TR (m2 K/W) - Thermal insulation - Thanks to their insulating properties, the underlays form a barrier over the cold floor, preventing heat loss in the room, thus reducing heating costs and providing thermal comfort for users.
PCv (mm) - Spot levelling of the substrate - Thanks to the asymmetrical shape of the underlay surface, i.e. with one side smooth and the other corrugated, it is possible to adapt to the substrate and even out minor irregularities. This prevents the floor from „sagging” on unevenness during use, while at the same time preventing the locks of the floorboards from separating and breaking off.
