Timber construction

Historically wooden constructions have offered poor acoustic isolation levels; particularly at lower frequencies where light weight walls and ceilings transmit low frequency noise very efficiently and make it impossible to comply with local building regulations.

CDM have recently participated in several projects to research and develop sustainable, cost effective and environmentally responsible isolation solutions for wooden framed and cross laminated timber structures – the results of which are very impressive.

Industrial equipment

The dynamic parts of large industrial machines will inevitably generate noise and vibration and, as
they are usually mechanically secured to the supporting structure, high levels of structure-borne
noise and vibration are likely. The introduction of isolation between the machine and its supporting
structure is a very effective method of controlling the noise and vibration and has been successfully
used in many different applications.


Noise and vibration are major sources of pollution directly affecting the health, life quality, productivity and social behaviour of large numbers of people. At home, at work, during recreation and rest, everyone needs the right environment to thrive. CDM offers a range of solutions to create room-in-rooms in any type of building.

Examples of silent spaces are:
Offices, apartments, hotel bedrooms and classrooms.


Many old urban buildings, such as warehouses and factories, are being converted for residential use to address inner city housing shortages. Almost all the internal walls, ceilings and floors will require a refit to make them compliant with local Buildings Regulations. CDM have a range of floor, wall and ceiling products and systems that will help transform even the oldest and noisiest building into a tranquil living space.

Building Base Isolation

Almost all new city buildings will be located close to a source of major transport noise and vibration such as an underground tunnel, a railway or tram line or a busy road. It is therefore important that consideration is given at the design stage to isolation of the building and, in some instances, to the isolation of noise sensitive spaces within the building.

Building services equipment

Modern buildings are all equipped with building services equipment, all of which produce noise and vibration. CDM offer a bespoke isolation solution for each of these pieces equipment so that they can be decoupled from the supporting structure thereby preventing noise and vibration becoming a nuisance in noise sensitive spaces.

Examples of building services equipment:
Elevators, electrical transformers, generators, HVACs, automatic doors and control rooms.

Gym & Sport

Locating gyms, fitness suites or other types of sporting facilities within a residential/commercial building always poses a great challenge for acoustic consultants. Without intervention the noise generated by these activities will be transmitted to noise sensitive areas within the building such as bedrooms or offices. CDM offer a range of floating floor systems to isolate these noisy activities from the rest of the building.

CDM-dBooster® is an innovative and proven concept which improves the isolation efficiency of CDM-GYM solutions. It’s also making the gym floor less dependent on the energy impact level introduced in the floor solution. CDM-dBooster® is designed to maximise the level of vibration isolation available from standard CDM-GYM floors and is effective for all areas of the gym: running machines, heavy weights and fitness classes.


Heliports are often a feature of modern urban buildings and are generally located on the roof. Unfortunately, particularly during take-off and landing, helicopters produce a lot of noise and vibration. In order to mitigate this effect, isolation of the heliport requires careful design to decouple it from the supporting building structure.

Pools & spa

Indoor or rooftop pool activities, spas and Jacuzzis all generate noise and vibration which, if left untreated, will become noise nuisance in other more noise sensitive areas of the building. CDM provide a range of solutions which will isolate these facilities both horizontally and vertically from the rest of the building.

Internal transit areas

Internal transit within buildings, such as car parking, forklift and pallet truck activity all produce noise and vibration which, without intervention, are all sources of noise nuisance. CDM provide a range of solutions to decouple these internal transit areas from the rest of the building.
