What Is CDX Plywood?

Plywood comes in a variety of different classes which can easily define its quality. CDX plywood is the lowest class of plywood and is often used in the construction industry or as a base for other materials. CDX plywood is much thicker and can be bought for low prices in large volumes. CDX stands for class C to D exposed plywood.

Formation

Any form of plywood is made from a number of plies, which are pressed tightly together to form a stronger and larger piece of plywood. Plywood commonly comes in plies of three, five, seven, and nine with the lowest numbers representing the highest class plywood. CDX plywood is made from pressing more of these plies together. This creates a much denser and thicker piece of wood.

Uses

CDX plywood is commonly used in the construction industry for the foundation and roofing of buildings. The wood is extremely durable, which makes it an ideal material to be used in a roofing base.

It does have some downsides, though. It cannot stand prolonged periods of exposure to water so it must be covered by another material. CDX plywood can also be used in many different craft projects. The surface of CDX plywood can be sanded easily, which will prepare it for a coat of primer and paint.

Knowing about CDX plywood will help ensure you are using the correct materials for your next project. Now you're all set.
