This Powerlon Vapour Control Layer (VCL) is a polyethylene based vapour control membrane that is reinforced with a scrim to offer sufficient tensile strength in roof and wall installations. The air barriers ensure that the building envelope is suitably sealed to control ventilation and prevent heat loss in compliance with Building Regulations Part L.
Fitted on the warm side of the insulation, this VCL protects insulates from interstitial condensation and as an impermeable air barrier, it also improves your building’s airtightness.
Key Features
- Air barrier for controlling ventilation
- Controls vapour to minimise interstitial condensation
