This is particularly helpful during the drying out period of a building. Suitable for both cold and warm roofs, the Air 160 breathable membrane is a high-quality underlay you can trust.
Covered by a ten-year manufacturer warranty, the Air 160’s three-layer composition is strong and durable. Roofing supplies are pleased to offer this Klober Permo Air 160 pre-taped for ease of installation and in two different roll sizes.

Please note: The underlay can be used to provide temporary weather protection. However, an exposed underlay will be subjected to UV light which may lead to premature failure. Therefore, the exposure period should be kept to a minimum. An underlay is not a total waterproof barrier and if used as a temporary waterproof covering, some rain penetration may occur. In certain conditions, particularly if there is persistent heavy rainfall combined with subsequent severe freeze/thaw conditions, an underlay should not be exposed for more than a few days. (BBA)
