Floating floors in commercial, public and industrial buildings

Many buildings feature floor assemblies that must withstand extreme loads, and at the same time provide excellent sound isolation. Buildings like convention centers, public halls, production facilities, warehouses, performing arts centers, and gyms see consistent high point loads or heavy impacts; such as dropped weights. Additionally, these areas incur potentially higher loads generated by people, pallet jacks, forklifts, maintenance equipment, or even cars and trucks. These objects cause vibration and structure-borne sound when moving on the floor.

When these areas are structurally connected to other areas of a building which require low noise conditions for living, working, education or vibration-sensitive equipment, proper sound and vibration isolation is required.

Generally, the most effective way to isolate vibrations and structure-borne sound is isolating the vibration source. This stops the sound and vibrations before they would be transmitted into other areas of the building. This can be done by creating floating floors, or by decoupling slabs, columns and walls.


Example of a floating floor

  1. flooring, e.g. marble, ceramic tiles, hardwood, vinyl
  2. floating concrete slab
  3. polyethylene film (8 mil)
  4. Regupol® / Regufoam® isolation materials
  5. concrete subfloor
  6. perimeter isolation strips
