Using a more modern approach to wood flooring, engineered wood flooring uses a layered construction made up of three layers of cross glued ply or spruce with a top layer of hardwood. This layered construction controls the natural movement of a wood floor. Engineered wood flooring can be resistant to moisture affording stability. It normally comes pre-finished with tongue and groove edges and depending on the manufacturer can be installed as a fully glued down floor, or on top of a suitable underlay as a floated floor. Some types have edges that click together, such as Kahrs flooring with Woodloc joints.
Aesthetically, engineered wood can be pleasing to the eye and is the preferred choice where underfloor heating is installed
