WISA-SpruceFR is a fire-retardant plywood product for use in construction. 

The fire retardant treatment significantly improves fire resistance properties of the product without compromising the plywood panel’s excellent technical properties. WISA-SpruceFR works equally as well as the base product – WISA-Spruce Special – in all kind of construction, especially in structural uses and load bearing structures.

The panel is made of certified Nordic Spruce - lightweight yet strong and rigid – and is an ideal panel for structural uses and load bearing applications like roofing, flooring, wall sheathing, packaging and joinery.

Its strength, workability and consistency make it perfect for projects that rely on quality, repeatability and accuracy.

WISA-SpruceFR is:


•            Structurally robust, so suitable for load-bearing applications.

•            Dimensionally consistent.

•            Class-B (B-s1,d0 and Bfl-s1) fire rated, meeting regulatory requirements for residential and commercial use.

•            Fully certified by globally recognised sustainable and responsible forest management certification schemes.

•            Ultra-sustainable through use of WISA® BioBond adhesive; replacing 50% of standard glue’s fossil-based phenol.
