What Are the Properties of Plywood?
The properties of plywood include increased stability, surface dimensional stability, high-impact resistance, chemical resistance and a high strength-to-weight ratio. Plywood is made from layers of wood pressed together and bonded with an adhesive.
Plywood has a cross-laminated structure and is durable through drastic temperature and moisture changes, making it ideal for flooring and framework in locations where exposure to moisture is likely.
Because of plywood’s laminated structure, it distributes weight over a large area on its opposite side. This means that plywood can accommodate up to twice its designated load for short periods of time, making It ideal for use in locations where seismic activity or strong winds occur.
There are four types of plywood, and each one is designed for a different application. Structural plywood is used in permanent structures like form work, flooring, bracing and manufactured beams. Internal plywood is used in interior structures that are aesthetically appealing and do not need to bear weight, such as wall paneling, furniture, ceiling linings and interior door skins. External plywood is used in external applications that are not subject to loads, such as exterior door skins, signs and cladding. Marine plywood is meant for use in marine applications, such as the hulls of boats and yachts. It minimizes potential water damage.
