About APA – The Engineered Wood Association
APA – The Engineered Wood Association is a nonprofit trade association of and
for structural wood panel, glulam timber, wood I-joist, structural compos-
ite lumber, and other engineered wood product manufacturers. Based in
Tacoma, Washington, APA represents approximately 150 mills throughout
North America, ranging from small, independently owned and operated
companies to large integrated corporations.
Always insist on engineered wood products bearing the mark of quality
– the APA or APA EWS trademark. Your APA engineered wood purchase is
not only your highest possible assurance of product quality, but an invest-
ment in the many trade services that APA provides on your behalf. The
Association’s trademark appears only on products manufactured by mem-
ber mills and is the manufacturer’s assurance that the product conforms
to the standard shown on the trademark.
For panels, that standard may be the , or . Panel quality of all APA trademarked
products is subject to verification through APA audit.
The APA or APA EWS trademark appears only on engineered wood products manufactured by members of
APA. The mark signifies that the manufacturer is committed to a rigorous program of quality verification and
testing and that products are manufactured in conformance with an APA or national standard such as ; or with a manufacturer’s building
code evaluation report or APA Product Report .
APA’s services go far beyond quality testing and inspection. Research and promotion programs play important
roles in developing and improving construction systems using wood structural panels, glulam, I-joists, and
structural composite lumber, and in helping users and specifiers to better understand and apply engineered
wood products. For more information, please see the back cover.
