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

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

Proper sound isolation can be achieved using standard construction materials with very low dynamic stiffness, such as mineral wool, glass wool or low density foams. However, these types of products are typically not suitable for higher loads or point loads, and have a relatively high creeping under loads. They may collapse and lose their acoustic properties, which may lead to cracks and instability of the floating concrete slab on top, and eventually provide less isolation performance. Therefore, excellent recovery properties under high loading and stress situations are required for permanent isolation effects and structural support.

Load Point and Load Reduction

Regupol America has developed 20 unique product types for floating floors available in different thicknesses, with load range performance from 0.5 psi to 362 psi. Regupol® Vibration and Regufoam® Vibration are remarkably stable under high static and dynamic loads. Great dimensional stability, high resilience, and durability make them the leading products in the area of heavy-duty floating floors. They deflect under load, while providing excellent sound isolation, and almost return to their original thickness when the load is removed.
