Air Tightness Membranes

The Vario KM Duplex UV is an intelligent, reinforced, laminated water vapour retardant climate membrane with a moisture-variable sd of 0.3 m to 5 m. Supplied in a 40m x 1.5m roll.

Protect Barriair with integrated lap and sealing tapes ia a highly effective air leakage barrier with vapour control qualities. Supplied in 1.5 x 50 metre roll.

PHS Astra Vapour Control Membrane Fixed SD 1.5m x 50m enables airtightness and vapour control in roof and wall constructions. It has an optimum fixed vapour resistance level of Sd 10m. This allows for an ideal level of vapour control, by preventing diffusion of internal vapour into the building envelope and prevents a build-up of condensation within the building envelope, which can cause mildew growth and structural damage.
