Floating Wide Plank Flooring

[tomh]

Before you go out and buy this flooring, you need to determine if what you propose is feasible at all. Wide solid plank flooring is inherently unstable and is prone to expansion, cupping and other responses to moisture and environmental changes. I have never heard of it being applied in anything but a true nail-down application on a built subfloor. Engineered wood and laminates are the usual choices for floating a floor over concrete.
