Here at Cleveland Wood Preserve, we treat our lumber onsite. Our chemical (NatureWood-CA?) is treated with Copper Azole type C (CA-C). CA-C is a copper-based waterborne preservative that provides long-term protection from rot, fungi decay, and termites for a wide variety of residential, commercial, and industrial building applications. We provide safe and long-lasting protection to the pressure-treated lumber we sell, making for excellent exterior construction.
