Each panel features alternating layers of wood strands coated with a high quality formaldehyde-free resin system and wax to deliver outstanding levels of airtightness.
A specialist coating is then applied to provide vapour control properties to ensure a premium performance OSB solution for super-insulated and passive buildings.
Available in a standard 2397 x 1197mm size, the panel uses a newly developed high performance coating to ensure consistently high vapour resistance across its entire surface. The smooth and durable surface has also been developed to provide superior bonding of airtight tape at panel joints.
Where air and vapour control layer (AVCL) membranes are notoriously difficult to seal, SmartPly VapAirTight is said to offer excellent seal adherence to prevent air leaks, condensation and consequential structural damage.
Manufactured from FSC-certified timber to the specification detailed in BS EN 300:2006, the rigid OSB3 panel is a robust and cost-effective alternative to specialist AVCL membranes.
