Powerlon AVCL’s

Air and Vapour Control Layers (AVCLs) act as barriers to prevent moisture within the building’s warm air from reaching the insulation layer and forming interstitial condensation.

AVCLs are impermeable and increase the building’s air tightness.

Powerlon AVCL membranes contribute to both BS 9250 for the air tightness in ‘a well-sealed ceiling’ and BS 5250 aiding the control of condensation within a roof space.
