Structural airtight OSB3 panel with integrated vapour control properties.
The product is suitable for both new build and renovation projects.
Structural airtight OSB3 panel with integrated vapour control and air barrier properties for use as structural sheathing in timber frame structures.
Airtightness is engineered into the OSB panel substrate, whilst SMARTPLY's in-house speciality surfacing technology provides an integrated vapour barrier with consistently high vapour resistance over the entire surface.
The coating also provides a smooth durable surface for superior bonding of airtight tape at panel joints. SMARTPLY PROPASSIV provides a sustainable and robust alternative to specialist AVCL membranes which are prone to damage by site trades during the construction process.
