What is acx plywood?

ACX plywood is a type of exterior-grade plywood known for its high quality and durability. The name ACX stands for "A" grade on one side and "C" grade on the other side, with "X" indicating that it is exterior grade. This means that one side of the plywood is of premium quality, while the other side may have some defects such as knots or patches.

ACX plywood is typically made from multiple layers of thin wood veneers that are glued together with waterproof adhesive, making it resistant to moisture and rot. It is commonly used for outdoor construction projects such as roofing, siding, and decking, as well as for interior applications like furniture, cabinets, and shelving.

ACX plywood is available in various thicknesses and sizes, with the most common thicknesses being 1/4 inch, 3/8 inch, 1/2 inch, 5/8 inch, and 3/4 inch. It is important to seal the edges of ACX plywood with a waterproof sealant to prevent moisture from penetrating and causing damage to the wood. ACX plywood is more expensive than standard plywood, but its durability and weather resistance make it a popular choice for projects that require a high-quality finish.
