Treated Wood Alert

All copper-based wood preservative technologies are not equal.

We at Viance have released findings from our ongoing field testing that compares the performance of micronized copper-treated (MCQ) wood to that of soluble copper-treated (ACQ) wood. We decided to release these results, as we find them to be surprising, and we wish to foster a transparent dialog in order to prevent possible early product failure.
