Engineered wood floors are real wood floors that are manufactured using three to five layers of different wood veneers. The sub layers can be of the same species, or of different species. The grainig of each layer runs in opposite direction, which makes it very stable. This means that the wood will expand and contract less than solid wood flooring during fluctuations in humidity and temperature.
The top layer of engineered wood flooring consists of high-quality wood.
Engineered floors can be nailed or stapled to a wood sub floor, or glued down to a wood sub floor or concrete slab. This makes engineered floors ideal for slab and basement installations, but they can be used in any room in your home.
This type of flooring can be sanded and refinished, but not as many times as solid wood flooring.
