Plywood

The strongest, lightest, most versatile utility and decorative product made from a renewable resource, plywood is kilo for kilo stronger than steel. Plywood was the first type of engineered wood to be invented. It is made from thin sheets of wood veneer, called ply or veneers. These are stacked together with the grain direction of the ply differing from its neighbours’ by 90 degrees (cross banding). The ply layers are bonded under heat and pressure with strong adhesives, usually phenol formaldehyde resin, making plywood a type of composite material. Laminating an odd number of ply sheets (3,5,7...) reduces warping, while increasing the number of ply layers increases the resistance to shearing forces. A common reason for using plywood instead of plain wood is its resistance to cracking, shrinkage, twisting/warping, and its general high degree of strength.

Certification
Our plywood has now obtained Chain of Custody under the AFCS, PEFC and FSC forest certification schemes. Please contact us to discuss our ability to source and supply certified, plywood products from our global network of producers.

Benefits of Plywood

Renewable Resource - A natural product from a renewable resource.
Beautiful- Preferred because of its warmth and natural grain patterns.
Strength- Unique cross-layered structure makes it kg for kg stronger than steel.
Efficiency- Uses more of the log than timber.
Versatility- Can be bent and formed to meet various sizes and shapes.
Durability- Long-lasting and good resistance to damage.



Types of Plywood
Plywood can be broadly classed as either ‘Exterior’ plywood or ‘Interior’ plywood. Veneer quality, glue type and timber species are the major contributing factors that determine the application of a plywood panel. CMC sell a vast range of plywoods which are grouped as follows:

Structural
Exterior
Interior
Flooring
Cladding
Non-Structural
Marine
Formwork
