Engineered wood floors are constructed from multiple layers of wood, the top layer or lamella is usually oak. The core of the board is made from plywood, this method of layering timber adds stability and strength.
Wood is a natural product and is hygroscopic – which means the floor absorbs and losses moisture. If the humidity changes the wood floor can swell or shrink as the floor’s moisture content changes. Changing humidity can be caused by seasons changes or the use of air conditioning or heating systems. Engineered flooring outperforms its solid counterpart in relation to humidity changes and engineered flooring can be used over underfloor heating. Due to the increased stability of an engineered floor, longer and wider planks can be produced.
