The work: Doggy Day Care
The problem: Noise created by dogs was loud and leaking badly into surrounding residential neighbourhood causing problems for owners..
The solution: Spray apply acoustic polyurethane system which reduced airborne noise to surrounding area. It also eliminated condensation and increased thermal performance .
The work: Liverpool Victoria HQ Bournemouth
The problem: Meeting rooms used for highly confidential discussions were fitted out by interior designers without any consideration for acoustics. Therefore even though they looked ok aesthetically there was considerable leakage.
The solution: The walls were injected with acoustic polyurethane insulation at intervals of every half metre. The insertions made good afterwards. The perimeter above the suspended ceilings were also blocked with barrier and acoustic sprayed polyurethane insulation. Result being a complete success. Db and actual physical noise dramatically reduced.
The work: Berkeley Homes Chiswick Gate
The problem: New high end development in West London. Problem caused in stairwells and stud walls were standard procedure has failed to achieve necessary DB ratings.
The solution: We decided on a retro fit to inject polyurethane acoustic foam into the step curvature by injection at intervals of quarter of a metre. The holes were 5mm in diameter. The stud walls have the same treatment. After installation the holes are made good. The project takes 1 full day and means structure is kept in place without disturbance.
Metropolitan Insulation were employed and added to our approved contractors list for the purpose of supplying and installing fully independent acoustic ceilings. From the point of consultation with our management team to the completion of works, they carried out the whole process with a high level of professionalism. Furthermore the feedback from those tenants involved is that the works were carried out in a fast clean manner. More importantly the reduction in noise both for airborne and impact was reduced by in excess of 50% meaning they can now sleep undisturbed.
I have no hesitation in recommending them to other Councils and commercials.
Kind regards, Mr P.
I am very happy with the professional service provided by Metropolitan Insulation. They were able to diagnose and fix my noise issue quickly, and proposed a more cost-effective solution than a competitor, which was effective.
All the best, Mrs E
Metropolitan’s latest installation has been well received and a great success.
The site which is a very upmarket Scandinavian poultry restaurant is situated in Middlesex Street close to Tower Bridge. The objective of the exercise was to reduce airborne noise to the flats above. Also the issue of reverberation
noise is combated.
When the restaurant is full the noise generated is dissipated by our system. This is another example of low density open cell acoustic foam being used successfully. It can be left open as in this instance or covered up also. The product is BBA certified and can have a zero fire rating added also. Modern semi commercials like this benefit hugely from technology.
Survivors UK Commercial Property Soundproofing
The Situation: Noise pollution through dividing patient rooms within the office complex
The Solution: We have successfully completed the design, build and installation of soundproofing at Survivors UK in Wapping.
This project involved taking down a side of external walls and dividing walls for the purpose of improving acoustic integrity and privacy in a highly sensitive environment. We also sealed existing fire doors without having to replace these, with acoustic/ smoke seals.
The system we used was the MetroSoundGuard system for the walls. This combines reduction for airborne and impact noise aswell as giving it high thermal conductivity. The result has been another outstanding bespoke solution in the City.
Airborne conversation has been reduced to a whisper and the clients are delighted with the results. Once again Metropolitan demonstrate they can deliver ‘sound’ solutions for your commercial and domestic needs/property.
