Plywood panels are made from thin sheets of wood veneer (« plies » with a thickness of between 0.8 and 4 mm) produced by peeling. What marks these panels out is the fact that the plies comprising them are cross-grained (at right angles). The plies are bonded together and hot-pressed for maximum cohesion.
The plies are usually arranged symmetrically either side of a central ply.
This cross-graining and the quality of the glue bonds (which are tailored to the panel’s intended use) ensure that plywood is:
- Dimensionally stable
- Resistant to outdoor conditions (service class 3)
Plywood has a wide variety of uses and is extremely versatile. It is a preferred material for construction, design, boat building, etc.
- Its mechanical performance allows it to perform a structural role in buildings
- It closely resembles solid wood
- It is flexible, allowing curved shapes to be created
- A wide range of finishes can be applied, depending on a panel’s intended use
