Your Online Source for Pressure-Treated Wood Information.</p> <p>First established in 1921, the American Wood Preservers Institute (AWPI) is the national industry trade association representing the pressure-treated wood industry throughout the United States. Member companies are wood pressure treaters, preservative manufacturers, and supporting companies working to conserve forest resources, preserve the environment, and extend the life of wood products through the manufacture of pressure-treated wood. </p> <p>The AWPI encourages, develops and promotes the production and acceptance of the wood preserving industry's products. The AWPI also promotes environmental stewardship and compliance with state and Federal regulations by all members of the wood preserving industry. The objectives of the association are to improve public acceptance of preserved-wood products, represent the industry on regulatory and legislative matters, and address all questions about the manufacture, use, disposal, and integrity of treated-wood products. The AWPI provides a wide range of technical, educational, and reference materials for use by members, distributors, and users of pressure treated wood. </p> <p>The AWPI was first established on January 26, 1921 as the Service Bureau Board of the American Wood-Preserver's Association (AWPA). On April 13, 1955, the name was changed to the American Wood Preservers Institute. The AWPI was first incorporated as an independent non-profit trade association in Illinois on June 24, 1958, and later in 1983 AWPI was incorporated in Virginia.</p> <p>From 1985 through 1996, the American Wood Preservers Institute has maintained its headquarters in Vienna, Virginia, a suburb of Washington, DC. On December 1, 1996, the AWPI moved to new offices in Fairfax, Virginia near the Dunn Loring metro station.</p> <p>Modern pressure treatment is accomplished by placing wood into a tightly-sealed cylinder and forcing preservatives into the wood cells. There are four major EPA-approved preservatives in commercial use for pressure treatment: water-borne preservatives, oil-borne preservatives, creosote solutions, and fire retardants. Many wood species can be pressure treated for durability. The treatment process does not alter the wood's characteristics. Pressure-treated wood will not shrink, swell, check, split, or warp to any greater degree than the same species left untreated. All preservatives used provide durability, however, selection of the preservative may depend upon the end-use of the structure-its type, color and appearance, the amount of human or animal contact anticipated, gluability, and other factors. </p> <h3 align="center">You need a browser that supports frames to view this site...</h3> <a href="main.html"><p>Home page</a><br> <a href="members_list.html">Membership listing</a><br> <a href="oaq.html">Often-Asked Questions</a><br> <a href="public.html">AWPI Publications</a><br> <a href="new.html">What's New?</a><br> <a href="about.html">About AWPI</a><br> </p> </body>
