Application

The product is suitable for both new build and renovation projects.

Description

Structural airtight OSB/3 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 AIRTIGHT provides a sustainable and robust alternative to specialist AVCL membranes which are prone to damage by site trades during the construction process.

Features and benefits:

Airtightness engineered into OSB substrate with specialist surfacing technology providing integrated vapour barrier and ideal surface for adhesion of tapes on the joints.
Easy to cut and fix.
Rigid panel - less susceptible to damage than membranes.
Consistently high vapour resistance.
Durable smooth surface.
High racking strength.
No added formaldehyde.
Equivalent air layer thickness (sd) (to BS EN 12572): Dry cup: 9.4 m (±1.0); Wet cup: 5.2 m (±1.0).
Air permeability coefficient at 50 Pa (tested to EN 12114): < 0.005 m³/(h.m²).
