WISA®-Spruce Special

A lightweight and economical, general purpose, spruce veneer plywood suitable for structural uses such as wall sheathing, flooring, roofing, formwork and joinery.

Plies are bonded using a phenolic resin, cross-bonded, weather resistant glue to EN 314-2, Class 3 'Exterior'.

For appearance grades and structural properties see 'Handbook of Finnish plywood' (visit manufacturer's website for details).

As wood is a living material, every panel is unique. Thus a photograph or a sample piece cannot represent all variations in colour, shade, graining, knots, etc.
