This long-length, extra-thick engineered stained hickory comes from an environmentally-certified mill no longer in the flooring business. They made some of the highest quality product we’ve ever sold and we were able to secure the last of their production. Although nearly uniform in color, natural variations in color are allowed. Milled with a micro-bevel and smooth surface, this flooring is suitable for above and below-grade installations, and additionally over water-based radiant heat systems. It can be nailed, glued or floated. The finish has a limited twenty-five year residential warranty.
