84 Lumber is now selling Ecolife Stabilized Weather- Resistant Wood for above ground applications in decks, fencing and similar projects. Ecolife integrates a wood preservative with a built-in stabilizer that is said to keep boards straighter and resist twisting, warping, cracking and checking.
Ecolife is fully compliant with American Wood Preservers Association (AWPA) standards and International Building Code (IBC) and International Residential Code (IRC) codes for most deck projects. Viance, the producer of Ecolife, offers a lifetime limited warranty on above ground preservative treatment, which includes wood framing members that are critical to the safety and performance of the structure, including joists and beams.
