A floating floor is not attached to the subfloor or the walls of a room. Instead, it is held in place by its own weight and by the interlocking mechanism between the individual planks or tiles.
The planks or tiles of a floating floor are installed over a foam underlayment or an adhesive underlayment, which can help absorb minor irregularities in the subfloor and provide cushioning and sound insulation.
In addition, some types of floating floors may use specialized clips or other mechanisms to hold the planks or tiles together and prevent them from shifting or separating over time. These clips are typically designed to be hidden beneath the surface of the flooring and are not visible once the installation is complete.
