Engineered Wood Association (APA)

Home / Glossary

The Engineered Wood Association (APA – The Engineered Wood Association) is a non-profit trade association that represents the North American engineered wood products industry. The association was founded in 1933 and is headquartered in Tacoma, Washington.

The mission of the APA is to promote the use of engineered wood products in construction and to provide technical information, research, and educational resources to the building industry. The association represents manufacturers of a variety of engineered wood products, including plywood, oriented strand board (OSB), glued laminated timber (glulam), cross-laminated timber (CLT), and other specialty products.

The APA sets standards for the manufacturing, grading, and testing of engineered wood products and works to develop building codes and standards that recognize the unique properties and benefits of these products. The association also provides technical support to architects, engineers, builders, and other professionals in the construction industry and conducts research on the performance and durability of engineered wood products.

In addition, the APA operates a certification program that ensures that engineered wood products meet rigorous quality and performance standards. The APA trademark is recognized as a mark of quality and performance in the industry and is used by manufacturers to signify that their products meet these standards.

Overall, the APA plays a critical role in promoting the use of engineered wood products in construction and advancing the state of the art in building technology.
