Reconsidering Rot-Resistant Framing Material

Copper- and borate-based preservative treatments have proven effectiveness, but structural plastics are more durable

When copper chromated arsenate (CCA) was eased off the market at the end of 2003 due to fears about its toxicity, builders needed to find new sources for rot-resistant structural lumber.

The new materials include lumber treated with alkaline copper quaternary (ACQ) or copper azole (CA); wood treated with borate, a naturally occurring mineral salt; or fiberglass-reinforced plastic lumber (FRPL), made from recycled plastics. The article includes a sidebar about new compounds and organic treatments in development.
