You can also lay engineered flooring over any flat stable surface including ceramic tile sheet vinyl and existing wood floors.
Traditional engineered hardwood.
Thinner engineered boards transfer heat better than thick solid wood and are more stable.
Installing a floating engineered hardwood floor works well at any grade level and over most types of subfloor surfaces.
This makes engineered hardwood flooring a better choice for installation over radiant heat sources over concrete whether it s below grade or above.
Engineered hardwood flooring overcomes these problems by constructing a multiple ply plank which counteracts twisting and remains flat and intact.
Engineered wood flooring looks very similar on the surface but it is made from a relatively thin layer of hardwood bonded over a substrate of high quality plywood.
Engineered flooring is somewhat less expensive than solid hardwood but most types can be sanded and refinished only once since the surface hardwood layer is relatively thin.
Concrete subfloors should be as flat as possible in accordance with the manufacturer s tolerances an eighth inch across a ten foot area is a good industry standard.
Floating floors are best because they don t need staples or nails that might puncture wires or hot water.
