Modern technology for every type of building.


The heating and cooling system designed specifically for residential buildings and offices where the laying height is at least 72 mm.

V-ERRE system is the ideal solution in buildings where laying space is limited but we don’t want to forego the advantages of a Valsir floor heating and cooling system. The coupling of a rigid pocketed sheet with a molded polystyrene sheet allows the space occupied to be significantly reduced.

By using the V-Acustic multi-layer soundproof floor covering over screed of 100 kg/m2, performance improvements of 28 dB are achieved.

Noise reduction to impact sounds. (UNI EN 12354-2 - App. C2) ΔLW > 28 dB
