Multifunctional underlay with ventilation feature for floating floors

ProVent presents a combination of a low density non-crosslinked polyethylene (LDPE) foam sheet and a high density polyethylene (HDPE) membrane.
Both materials are laminated together to create a multifunctional underlay with vapour barrier included..
The foam base of ProVent is ribbed (wavy). When extruded the thickness of product at the highest point is 3.5mm. In working conditions, under the floor pressure, ProVent is approximately 3mm thick.
