In applications where wood may be exposed to moisture, insects or fungal organisms, preservative-treated wood can help ensure a building’s durability. In this presentation, participants will learn about the manufacturing process for pressure-treated wood, available products and their differences, and how preserved wood is used in construction.
Topics include an overview of preservative treatments, desired service life and exposure conditions, AWPA Use Category standards and current issues concerning the safe use of treated wood. Participants will also receive instructions for free downloading of the Treated Lumber Guide smartphone/tablet app.
