With a lifetime limited warranty against termite damage and fungal decay, Wolmanized® Residential Outdoor® wood is backed by the Good Housekeeping Seal.

In addition, pressure treated lumber has the environmental advantage of wood. A renewable resource, wood from well-managed forests is grown and harvested in a responsible manner. This means the wood used today to manufacture pressure treated lumber is continually replenished in healthy forests every year. And, because the treatment process extends the useful life of the wood, structures made with pressure treated lumber remain in service for many years.

The preservative in Wolmanized® Residential Outdoor® wood is a formulation of copper azole (also known as CA-C). The primary ingredient in CA-C is copper, an effective fungicide. As some fungi can tolerate copper, an additional co-biocide is needed to control them. The two azoles in CA-C are tebuconazole and propiconazole. When used together, these azoles are more effective than the sum of them used separately. This combination was granted a patent.
