Floating

Floating installation: A floating installation is where the flooring is installed on top of a layer of underlayment or moisture barrier. The individual planks are glued together using a tongue and groove adhesive such as PVA wood glue. Space for expansion should be left at the edges of the room. Cabinets and walls should not be installed on top of floating floors. Subfloors should be flat and it is not recommended to install on top of more than one layer of existing flooring.
