Preserve® CA (Decay & Termite Resistant)

Preserve CA Logo

Preserve® Wood DeckPreserve® is a family of soluble copper-based preservative solutions for exterior wood products that provide long-term protection from fungal decay and termite attack for a wide variety of residential, commercial, and agricultural construction applications. In each Preserve® solution, the soluble copper provides most of the protection to the wood, and the co-biocides complete the formulation by adding the protection against the copper-tolerant fungi. Soluble copper is very effective in penetrating the cells in the wood fiber during the pressure-treatment process, providing for optimum long-term protection.

Wood Preservative Treatment

The Copper Azole (CA type C) variety of Preserve® used by Sunbelt is a wood preservative formulation made of soluble copper and uses organic triazoles (tebuconazole and propiconazole) as the co-biocide to control copper-tolerant fungi.
