What is the difference between Engineered and Solid Wood Flooring?

Each type of flooring has its specific use and choosing one over the other is dictated by your lifestyle and needs. Solid wood should be in a moisture-controlled environment.
Engineered wood flooring consists of a multi-plied, cross-stacked backing with a real wood veneer (top layer of a selected species), it can be used on grade, above and below grade. Engineered wood flooring is more dimensionally stable so it can be installed in areas where solid wood is not compatible due to moisture. Engineered wood can be glued down over various sub floor. Some engineered woods can be nailed down which require a wood sub floor. It can also be laid as a floating floor where the tongue and groove are glued together, but the floor is not anchored to the sub floor.
Each has their specific use and is dictated by your lifestyle and specific needs, although visually identical once installation has been completed. Solid wood has been used for hundreds of years but please note; it should be installed in a moisture-controlled environment therefore it is not recommended for areas such as cellars, basements, conservatories or over under-floor heating systems. Engineered wood flooring is typically easier to install for the DIY customer, and offers a wider range of design, styles and finishes.
