Copper Azole Wood Preservatives

Copper azole-treated wood is greenish-brown and has little to no odor. Type A (also known as CBA-A) contains copper, boric acid, and tebuconazole. Type B (also known as CA-B) contains higher concentrations of copper and tebuconazole but no boric acid. Copper azole is registered for a variety uses above and below ground, as well as in freshwater and marine decking applications.

For help selecting the proper type of treated wood for any setting, consider consulting the primary standard-setting body for treated wood, the American Wood-Preservers' Association (AWPA).
