floating floor
The upper layer of floor construction supported on battens, mountings or a resilient sheet membrane of damping material such as expanded polystyrene or mineral wool to provide acoustic isolation.
floating floor
A floating floor is a floor that does not need to be nailed or glued to the subfloor. The term floating floor refers to the installation method, but is often used synonymously with laminate flooring in a domestic context.
A sprung floor is a special type of floating floor designed to enhance sports or dance performance. In general though the term refers to a floor used to reduce noise or vibration.
A domestic floating floor might be constructed over a subfloor or even over an existing floor. It can consist of a glass fibre, felt or cork layer for sound insulation with neoprene pads holding up a laminate floor. There is a gap between the floating floor and the walls to decouple them and allow for expansion; this gap is covered with skirting boards or mouldings.
Floating floors as used in sound studios can be either just larger versions of the domestic variety, or much larger constructions with slabs of concrete to keep the resonance frequency down. The manufacture of integrated circuits uses massive floating floors with hundreds of tons in weight of concrete to avoid vibration affecting mask alignment.
Floating floors are one of the requirements for the THX high-fidelity sound reproduction standard for movie theaters, screening rooms, home theaters, computer speakers, gaming consoles, and car audio systems.
While floating floors add to the appeal of a home, they are not recommended for areas that may get wet, i.e. bathrooms and near exterior doors.
