The characteristics of structural plywood

Structural plywood can be worked with conventional wood working tools. It can be cut, drilled, bored, planed and sanded with ease. Due to its cross-laminated construction plywood panels can be nailed with hand or power driven nails to within 10mm of the edge without fear of splitting or other edge damage.

Additionally, the cross-laminated construction imparts impact resistance to the structural plywood panels. Damage during transport, handling and site installation is therefore minimised.

After the durability of the Type A bond used in its manufacture, the dimensional stability of structural plywood under moisture content and temperature changes is its most important characteristic. Because of its cross-laminated construction, its stability is generally superior to other timber and wood based panels.

During the design of the floor, this movement can be accommodated by providing small gaps at panel perimeters. For small floor areas, the gaps left between panels when laid by hand should accommodate normal hygroscopic movement.

Structural plywood usually has thicker face veneers than those used in concrete formwork plywood or marine plywood. This gives it far greater strength and stiffness in the direction of the face grain.
