SupaTimber® CCA

SupaTimber® CCA pressure-treated wood is protected from decay and termite attack with Chromated Copper Arsenate (CCA) and is suitable for certain commercial and industrial applications.

This wood has been preserved by pressure EPA registered pesticide containing inorganic arsenic to protect it from insect attack and decay. Wood treated with inorganic arsenic should be used only where such protection is important.

Inorganic arsenic penetrates deeply into and remains in the bpressure treated wood for a long time. However, some chemical may migrate from treated wood into surrounding soil over time and may also be dislodged from the wood surface upon contact with skin. Exposure to inorganic arsenic may present certain hazards. Therefore, the following precautions should be taken both when handling the treated wood and in determining where to use or dispose of the treated wood.

Specify SupaTimber for industrial or commercial applications in which conditions conducive to termites and fungal decay are present. These conditions would include any situation in which wood will be in contact with water, soil, concrete or masonry, subject to periodic wetting or exposed to moisture or high humidity.

Why use Treated Wood?

Some treated woods are manufactured with a built-in water repellent which keeps the wood looking good longer. While regular preservative treatments protect wood against termites and rot, they do not slow down moisture damage which can cause warping, cracking, and deterioration of appearance. If you are looking for a water-repellent feature, Ecolife repels water for up to three years, and saves homeowners the time and money from having to seal their decks soon after installation.
