CDX plywood is a relatively inexpensive and convenient sheet of plywood. Unlike hardwoods, however, CDX plywood is not treated with a waterproofing agent. It is sold as an additional support layer beneath shingles and roofing felt and behind siding and insulation.
Whether or not you decide to use CDX is a personal decision and will depend on the specific needs of your home.
Most lumberyards carry CDX plywood as a standard stock item. This utility-grade plywood is a more affordable alternative to marine-grade plywood. While it may be cheaper than marine-grade plywood, ACX is more appealing.
In addition, ACX is water-resistant, so it’s a good choice for exterior applications.
CDX plywood is available in three-inch, five-inch, and nine-inch thicknesses. It is made by bonding three layers of wood together. Each layer is made of a different grade of plywood veneer. For example, CDX plywood has a C-grade veneer on one side and a D-grade veneer on the other.
These pieces are then bonded together by adhesive that allows only a small amount of moisture to pass through.
A CDX plywood’s name explains a lot about how it is made. The combination of three wood sheets and a special glue ensures that it stays intact for a very long time. This is more durable than solid wood, which can expand or contract due to external influences.
However, it’s still not waterproof and can only withstand a limited amount of water.

What is CDX plywood vs plywood?
Plywood is an engineered wood product made up of several layers (or plies) of wood veneer that are glued together with the grain of each layer running in opposite directions. This cross-graining makes plywood much stronger and more rigid than solid wood.
CDX plywood is a lower grade of plywood that is commonly used for sheathing and subflooring. It is made up of plies of softwood veneer, which are glued together with the grain of each layer running in the same direction.
This makes CDX plywood much weaker and more flexible than plywood.
What type of plywood is for outdoor use?
There are three main types of plywood: softwood, hardwood, and engineered. Softwood plywood is typically made from cedar, fir, spruce, and pine, and is often used for construction and other structural purposes.
Hardwood plywood is made from lumber scraps and is often used for cabinets, furniture, and flooring. Engineered plywood is made from multiple layers of plywood glued together with a waterproof adhesive, and is often used for outdoor applications such as siding and roofing.
When would you use CDX plywood?
CDX plywood is typically used as an exterior sheathing material and is often used to build sheds, cabinets, and other woodworking projects. It is also often used as a subflooring material.
What grade of plywood is CDX?
CDX plywood is the highest grade of plywood, and is typically used for roofing and siding. It is made with a cross-laminated construction, which gives it superior strength and durability.
What is the difference between CDX and ACX plywood?
There are a few key differences between CDX and ACX plywood:
-CDX plywood is made with lower-quality wood, so it’s not as strong or durable as ACX.
-ACX plywood has a smooth, sanded surface on both sides, while CDX has a rough surface on one side and a smooth surface on the other.
-ACX is typically more expensive than CDX.
What does CDX stand for for plywood?
The term “CDX” refers to the species of wood used to manufacture the plywood. “C” stands for coniferous, or evergreen, trees; “D” stands for domestic, meaning the plywood is made from North American trees; and “X” means the plywood is made with exterior-grade adhesive.
How long will pressure treated plywood last outside?
Pressure treated plywood is made to last a long time outside. The chemicals used to pressure treat the plywood help it resist rot, insects, and water damage. However, the chemicals will eventually break down and the plywood will need to be replaced.
The lifespan of pressure treated plywood depends on the climate and exposure to the elements, but it is typically around 20-30 years.
Can I use plywood for exterior siding?
Plywood is a material made up of layers of wood veneer glued together. It is an inexpensive and versatile product that can be used for a variety of applications, including exterior siding. When used as siding, plywood is typically installing horizontally over studs on a home’s exterior walls.
It is important to use a quality plywood product that is rated for exterior use and to properly seal and paint the plywood to protect it from the elements.
Is OSB suitable for outdoor use?
Yes, OSB is suitable for outdoor use, as long as it is properly sealed and protected from the elements. OSB is a durable material that is resistant to water and rot, making it ideal for use in outdoor applications.
However, OSB is not as resistant to UV light as other materials, so it should be sealed and protected from direct sunlight to extend its lifespan.
Can CDX get wet?
Yes, CDX can get wet. CDX is a construction-grade plywood that is often used for sheathing in walls and roofs. It is made with waterproof glue and is designed to be used in damp or wet conditions. However, if CDX gets too wet, it can delaminate and fall apart.
