Water repellent WISA-SpruceWR facilitates construction in varying humidity conditions
UPM Plywood introduces a new water repellent WISA-SpruceWR plywood that enables efficient and effortless construction even in changing weather and humidity conditions. The water repellent yet breathable surface of WISA-SpruceWR slows down the absorption of moisture into the panel while allowing it to evaporate. Thanks to the wood-based treatment agent, WISA-SpruceWR is a genuinely sustainable and safe choice made from renewable raw materials. Designed for structural uses, WISA-SpruceWR provides significant benefits especially for developers and builders. WISA-SpruceWR is available in four common thicknesses (12–21 mm), in both straight-edged and easy-to-install tongue-and-groove options. Made entirely of spruce, WISA-SpruceWR’s technical properties are the same as those of regular WISA-Spruce plywood: the panel’s strength and light weight make it ideal for all kinds of frame construction, such as walls and floors.
