What is a floating floor and how does it differ from other types of flooring installations?

A floating floor is a type of flooring installation where the individual planks or tiles are not directly attached to the subfloor. Instead, they are locked together and float over the subfloor. This differs from other types of flooring installations, such as glue-down or nail-down, where the flooring is secured directly to the subfloor. Floating floors are easier to install, can be installed over existing flooring, and are often more forgiving of imperfections in the subfloor.
