Treated Southern Pine is the greatest “bang for the buck.” Treated lumber has been around
for years, so you know what to expect. Treated lumber has a lifetime warranty but will require some maintenance to keep
it looking nice. In the past, wood was CCA treated (copper, chromium & arsenate) but because these are now considered
hazardous waste they are no longer used. We use Wolmanized natural select treated lumber which is treated with a copper-based
preservative with an organic fungicide. Learn more about this at
www.naturalselect.com. The other draw back to treated lumber is that it comes from the lumberyard extremely wet. After it is installed, it
tends to shrink and warp as the sun dries it out. This can be helped by treating the wood fibers with a product called
Penofin.
