Selection of plywood grades and types including ACX, CDX and CDX Radiant Barrier

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 building applications.
