PHS Polaris Air Block is a double-layered, high performance, internal vapour control membrane, with a fixed Sd.
PHS Polaris Air Block is used as an airtight and vapour controlling membrane. It is installed on the side facing the heated interior, the warm side of the building fabric. It is suitable for use on vented flat ceilings and steeped roofs, in new builds and retrofits, and on timber, steel and masonry residential constructions.

To create an airtight envelope, all perforations, overlaps and joints must be sealed using an airtight tape or sealant. Avoid membrane and tape stress during and after installation, so as membrane tears do not occur and the quality of the tape joint is not compromised. Prior to installation, all bonding surfaces should be clean, dry and free of grease, oil, etc. In some applications it might be necessary to prepare the substrate surface with PHS Primer.
