SMARTPLY AIRTIGHT

SMARTPLY AIRTIGHT is a structural OSB 3 panel with an integrated vapour control layer and air barrier properties.

Designed for use as internal structural sheathing on the warm side of the insulation in timber frame structures.

The integrated vapour control layer and air barrier properties eliminate the need for additional air and vapour control layer membranes.

SMARTPLY AIRTIGHT is suitable for both new build and renovation projects and the specialist coating provides a suitable surface for the superior bonding of airtight tape at panel joints. 

Conditioning and expansion gaps required.
