Wood-based products, including plywood, may be subject to decay and/or termite attack under certain conditions. Among the many different preservatives available for wood, borates are generally preferred for indoor uses. Borate-based preservatives can be used to treat solid wood, engineered wood composites and other building materials like studs, plywood, joists and rafters. Treated plywood is utilized in many applications where preservative characteristics are required, such as in concrete forming and all-weather wood foundations. Treated panels make up a large part of the plywood market. Some wood preservatives have been known to interfere with the bond integrity of glued wood specimens.
