Most new buildings within cities are likely to be located within close proximity of a major source of noise and vibration, such as an underground tunnel, a railway line, a busy road or another internal source of noise and vibration.
In order to protect a building or part of a building from the consequential structure-borne noise and vibration it may be necessary to support it using

Floating floors are used where there is a requirement to either protect a noise sensitive area or to isolate an area where excessive noise is produced. They work by isolating the working floor from the supporting structure and can be designed to take domestic, commercial or industrial loads. CDM-FLOAT

Fully isolated walls are often required to prevent noise travelling between adjacent rooms or from the structure of the building. The sound insulation and vibration isolation of these walls can be improved by introducing resilient fixings to decouple them from each other and/or resilient strips to isolate them from the supporting structure.

There is often a requirement for a suspended ceiling to protect an area from noise generated by activities in spaces directly above. CDM’s range of resilient hangers maximise the sound insulation of suspended ceilings by isolating them from the supporting structure, therefore providing significant improvements in airborne and impact noise levels.

When an isolated floor, wall and ceiling system are installed together to form a completely isolated room, a box-in-box construction has been created.
In many instances, depending on the particular building design, structural isolation may also be a feature of the box in box. This high level of isolation provides the ultimate performance in
sound insulation. back to top of page
