Since 1947, WWPI has represented the interests of the preserved wood products industry throughout western North America. The membership consists of companies that either manufacture products, are directly affiliated or provide a service to the preserved wood industry.
Our site includes information on all services WWPI delivers to its members and those specifying and using preserved wood products. You can also review the Institute’s current membership and links to other sites in the wood preserving industry.
