4 in. x 8 in. T&G panels are ideal for the sub-floor construction of residential single and multi family houses as well as light commercial construction and modular mobile homes. Rated structural panels are manufactured using wood strands and waterproof adhesives, and do not contain added urea-formaldehyde resins. The wood strands are arranged in cross-oriented layers to provide strength and performance properties similar to equivalent thicknesses of plywood. The result is a structural engineered wood panel that is consistent in quality with no core voids. No special tools are required to work with the panels. SUB-floor panels, with a grade stamp, are certified by the APA (The Engineered Wood Association) to ensure the quality is built into every panel and that it meets North American building codes.
