Powerlon Air Barrier Membrane is a high performance non woven 112gsm membrane that will increase energy efficiency as it improves the air tightness in the building. This membrane is CE marked and certified for use in roofs, walls and floors. Powerlon Air Barrier is made from reinforced polyethylene coupled with a high tensile scrim for extra durability and strength. Powerlon Air Barrier prevents interstitial condensation by minimising the warm air that reaches the layer of insulation.
