Powerlon VCLs are polyethylene based vapour control membranes with a mono filament reinforcement scrim to provide sufficient tensile strength in wall and roof insulations. Air and Vapour Control Layers (AVCLs) ensure that the building envelope is properly sealed to control ventilation and prevent heat loss in compliance with Building Regulations Part L. Installed on the warm side of insulation, AVCLs protect insulates from interstitial condensation.
