American Wood Protection Association
The American Wood Protection Association (AWPA) is a non-profit organization which promulgates voluntary wood preservation standards. AWPA Standards are developed by its technical committees in an ANSI accredited consensus-based process that involves individuals from all facets of wood preservation: Producers of preservatives and preservative components; producers of treated and untreated wood products; end users of treated wood; engineers, architects and building code officials; government entities, academia, and other groups with a general interest in wood preservation. AWPA's Standards are universally specified for wood preservation in the USA, and are recognized worldwide.
AWPA's Mission:
AWPA seeks to improve the performance and longevity of sustainable wood products by developing competent, reliable, international standards through an open, consensus-based process, and to serve society as a resource for knowledge on all aspects of wood protection.
AWPA’s Vision:
AWPA envisions a world that understands the value of the sustainable use of wood products and embraces consensus standards as a means to ensuring the responsible use of the most treasured natural renewable resource: Our forests.
Announcements
Did you know that most of the funding for AWPA’s standards development process comes from the sale of the AWPA Book of Standards? Every treating plant, laboratory, specifier, and inspector should have a current edition on-hand, so please be sure to purchase updated copies each year to help AWPA cover the cost of standards development. If you don’t have the 2025 edition, your standards are already outdated! The 2025 AWPA Book of Standards is available in two versions:
A 698-page printed book which may be purchased online at the AWPA Store, or by mail or fax. Click here to download a printable order form.
A searchable online version which requires a subscription for access. Single-user and multi-user subscriptions are available for purchase through the AWPA subscription portal. After purchase, standards may be accessed online through the AWPA Standards Library.
