The American Wood Council (AWC) is a non-profit organization that provides information and resources for the design and construction of wood-framed buildings. It was formed with the mission to increase the use of wood in construction through the development of design tools and building codes, standards, and guidelines. They represent the North American softwood lumber industry and provide technical resources, including design software, engineering guides, and standards for architects, engineers, builders, and other construction professionals.
The AWC is a membership organization that is made up of companies and organizations involved in the production and distribution of wood products, as well as companies that provide services to the wood products industry, such as engineering firms and lumberyards. They were established in the 1940s, as a way to provide technical support to the wood products industry and promote the use of wood as a construction material. The organization also advocates for the use of wood in construction at the national and international levels, and works with code-making and standard-setting bodies to ensure that building codes and standards are favorable to the use of wood.
The American Forest & Paper Association (AF&PA) is a trade association that represents the forest products industry in the United States, which includes the pulp, paper, packaging, and wood products sectors. They were established in the early 20th century and have been representing the industry for more than a century. The organization’s mission is to promote the sustainable growth and use of wood and paper products, and to advocate for policies that support the forest products industry.

Published by the AWC and AF&PA. (73 pages)
The American Wood Council (AWC) is a non-profit organization that provides information and resources for the design and construction of wood-framed buildings. It was formed with the mission to increase the use of wood in construction through the development of design tools and building codes, standards, and guidelines. They represent the North American softwood lumber industry and provide technical resources, including design software, engineering guides, and standards for architects, engineers, builders, and other construction professionals.
The AWC is a membership organization that is made up of companies and organizations involved in the production and distribution of wood products, as well as companies that provide services to the wood products industry, such as engineering firms and lumberyards. They were established in the 1940s, as a way to provide technical support to the wood products industry and promote the use of wood as a construction material. The organization also advocates for the use of wood in construction at the national and international levels, and works with code-making and standard-setting bodies to ensure that building codes and standards are favorable to the use of wood.
The American Forest & Paper Association (AF&PA) is a trade association that represents the forest products industry in the United States, which includes the pulp, paper, packaging, and wood products sectors. They were established in the early 20th century and have been representing the industry for more than a century. The organization’s mission is to promote the sustainable growth and use of wood and paper products, and to advocate for policies that support the forest products industry.
