The Strotex 140 PI vapour barrier foil is a durable multilayer coating that protects the roof structure and thermal insulation layer against the inflow of water vapour from the rooms inside the house, as well as heat losses caused by ventilation. Ensuring the exchange of water vapour, the product prevents the accumulation and condensation of moisture in the roof structure (between thermal insulation and plasterboard).
To ensure correct performance of the thermal insulation system, it is recommended to simultaneously lay a vapour barrier along with the installation of a thermal insulation layer and a vapour-permeable foil.
STROTEX 140 PI vapour barrier foil is designed for vapour-tight insulation layers of ceilings, roofs and walls, as well as a protective layer against dampening of the thermal insulation. It is a barrier to water vapour and wind. STROTEX 140 PI can be used as an insulating layer in all types of ventilated and non-ventilated, sealed and aerated roofs.
