Why does a floating wood floor have better stability?
Floating Wood Floors are manufacturered with a decorative real wood species veneer top layer adhered to a plywood type base. The amount of ply-layers that the base may have will vary depending on the wood flooring manufacturer. Each thin wood ply layer when cross layered in the opposite direction to other ply-layers and glued at the factory greatly reduces the ability of the engineered hardwood floor to expand and contract and it becomes a very stable and strong floor. With any other wood flooring that’s nailed down or glued down over a subfloor the natural movement within the wood floor during seasonal change is restricted because it’s secured solidly to the subfloor. Seasonal expansion and contraction can cause the edges of each of the boards to cup upwards or cause the boards to dry out and contract showing unsightly gaps between the boards (usually during the dry heating season). A floating hardwood floor virtually eliminates this cupping and/or contraction during seasonal relative
