Nowadays engineered wood flooring has been widely used. It looks like solid wood flooring while less expensive. And it is more stable and versatile than solid hardwood flooring. Engineered flooring is usually constructed in layers. The top lay is real wood, usually using oak, teak, maple and so on. Underneath its showy veneer, though, is a simple, relatively inexpensive core made from ply-woods or HDF. Veneer thicknesses range from 0.6 to 6.0 mm (1/32 to 1/4 inches).
