Acoustic Floating Floor - Stud Rail System Type SRS

SRS FLoor_365_365.jpg

The principle of supporting two separate masses to significantly improve the standard acoustic mass law performance is well understood.

The term “Floating Floor” is a relatively new expression that has gained favour in more recent years but the method of supporting a floor structure on resilient bearings off a structural slab has been applied and developed by Christie and Grey over much of its 100 year history. Examples of this work still in existence date back to the early 1960's.

The development of structural materials has enabled architects and engineers to make more and more use of lightweight structures in modern building designs. This has highlighted the need to consider carefully the noise, shock and vibration transmission loss characteristics of these structures.

In particular, for high rise buildings, the proximity of “noisy or high” and “quiet or critical” areas significantly increases the potential for use of acoustic and vibration isolation materials, including floating floors.

For example, it might be necessary to isolate a plant room from office accommodation below, reduce external noise such as low flying aircraft penetrating the roof of a building or reducing the transmission of footfall impact noise from one apartment to another below.

SRS Acoustic Floating Floor Systems have been used successfully in applications such as Plant rooms, Offices, Prestigious Apartment Blocks, TV, Radio and Recording Studios, Cinemas, Concert Halls and Audiometry rooms.


  • Laminated steel and natural rubber elastomer bearings are located beneath rigid steel channels positioned to suit the load distribution arrangement.
  • Natural rubber bearings are true elastomers and are applied within their linear stiffness range to achieve the required design performance
  • low creep and resultant design life.
  • Standard design can provide natural frequencies down to 6 Hz.
  • Profile permanent steel shuttering keyed to concrete for greater rigidity of floating floor slab.
  • Floor thickness from 100 - 300 mm with imposed loads of up to 20 kN/m2.
  • TV
  • Radio and Recording Studios
  • Cinemas
  • Nightclubs
  • Plantrooms
  • Audiometry rooms
  • Anechoic chambers
  • Prestigious Apartment Blocks
  • Offices
  • Concert Halls
  • Laser Welding Machines
  • Bowling Alleys
  • Dance Studios
