Plywood panels are composed of at least three veneers. All the veneers in WISA birch plywood are made of birch. Birch plywood is used where special strength and/or a hard and smooth surface is required. All the veneers in WISA spruce plywood are made of spruce. Spruce plywood, which is light weight and cost effective, is widely used for construction.
Coatings, CNC-machining and cutting-to-size convert plywood panels into ready-to-install products. Coatings improve the plywood's resistance to wear, impact, chemicals and weather. Films and laminates imprinted with various patterns improve the panel's frictional properties.
