Engineered wood
Until the advent of engineered hardwood flooring, few builders or remodelers would recommend or risk installing a hardwood floor over a below-grade concrete surface. Because solid wood changes dimensions with fluctuations in temperature and humidity, the chances of warping and cracking were too great. In addition, there were few reliable options for installing wood flooring without traditional nails or screws. Engineered wood floors, however, provide a more stable substrate for the planks while delivering the look and feel of a solid wood floor. They feature a thin veneer layer of solid wood that is laminated to plywood backing. Plywood is more dimensionally stable than solid wood, allowing the planks to withstand temperature and moisture fluctuations without warping. Engineered hardwood planks are installed one of two ways. Some varieties are designed to be glued to the basement floor using an industrial adhesive. Others are “floated” over a layer of thin foam sheeting; the planks are held in place by a system of interlocking ends and edges. Engineered wood planks are priced from $2 to $20 per sq. ft. Their factory-finished veneer is virtually maintenance-free. Installation is about $4 to $5 per sq. ft., regardless of whether the planks are glued down or floated. By: Rich Binsacca
