More breathable than other types of air-open underlay, Permo Air HT membrane by Klober reduces the risk of condensation forming in the roof space.
The underlay can be used with slate, tile or Colorbond roofing and is suited to both cold and warm climates. It responds well when exposed to moisture, water, wind and humidity, as can happen during the drying out period of construction. With its strong four-layer construction, Permo Air HT exceeds the Australian standards AS/NZ 4200.1:1994 and AS 530.2-1993. It is exclusively distributed by Premier Slate. klober.com.au
