Copper Azole Type C (CA-C)

Copper Azole Type C (CA-C) is a widely used pressure-treatment that protects lumber from fungal decay and termites. CA-C offers broad-spectrum protection by using a combination of copper and co-biocide azole. CA-C meets EPA standards and the standards set by the American Wood Protection Association (AWPA). CA-C replaced older CCA treatments after they were phased out in 2003.

The Green Shield Difference

Instead of “Type C” Copper Azole, Green Shield Deck Builders uses “Micronized” Copper Azole, a specialized form of Copper Azole preservation treatment. Compared to type C prevention MCA offers a lower corrosion rate, reduced copper leaching into soil and water, and is more cost effective.
