Plywood

Plywood is one of the most widely used and trusted wood products in use today. Considered the original engineered wood product, plywood is manufactured from thin layers of cross-laminated wood veneers and bonded with strong adhesives under heat and pressure. The result is a graded, dimensionally stable structural panel with an excellent strength-to-weight ratio that can be used for subflooring, sheathing, shear walls and other demanding building applications.
