Permo® air is a low resistance air-open underlay, suitable for pitched roofs. It is the ideal solution where there is a high risk of condensation forming in the roofspace. Being both air open & vapour permeable further minimises the risk of condensation forming, particularly during the drying out period of a building.
As Permo® Air 160 roof membrane is BBA & NHBC approved, no additional ventilation is required, ensuring it is time and cost effective, making it a perfect solution for new-builds.
