WISA-Roof is a spruce plywood with strength oriented construction designed for load bearing roofing sub-structures. The unsanded face gives better grip on the roofing site and thereby decreases the risk of accidents. WISA-Roof is surface treated which gives protection during construction work. This quick and easy to install panel saves time and money - the most valuable inputs you have.
