:confused: I am tearing up the cold tile flooring in my family room and foyer. The question is, if wood flooring is installed over an above grade cement slab, what is the best material? I've heard conflicting theories. One being, never install wood over cement. Another, both work however engineered wood is a better choice because of the structure of the product, it deals better with moisture generated from a slab AND I won't have height issues as engineered flooring is glued over a vapor barrier direclty to the slab which will basicly match the height of my existing floor. Meanwhile, conventional flooring requires a 3/4" plywood subfloor under the 3/4" oak material rasing my floor almost one inch from it's height now. The last bit of advice was, both will work however conventional flooring is best for wear issues, the wood "feel" when walked on and the product/install labor cost is less.
