When it comes to sound proofing the only sound proofing we do is roofs and floors. We do not undertake sound proofing of walls or windows. Sound Proofing is a very complex application and we only specialise in the two main applications as listed above. The fact is most noise pollution will come through the roof so that should normally be the first step. We stock a number of different acoustic products for most applications.

Sound Proofing Roofs

Sound Proofing

In the application of sound proofing roofs we generally insulate with two layers of Aerolite Think Pink. This product is well known for its accoustic values. In fact a single layer of 135 mm Aerolite has a NRC of 1.2. Therefore installing  two layers will reduce a huge part of the external noise by up to 90%. Having said that if you are playing loud music with heavy base sounds we install higher density layers first and then apply the Aerolite.

In night clubs and pubs we will generally fit high density insulation layer first for the base sounds. Then we would lay two or three layers of the Aerolite 135 mm.  Most noise will travel through the roof space. However  with extreme sounds from pubs and clubs. Remember that heavy base sound will travel through wall as well as floors.

I really in these applications walls should be insulated as well. This is not an application that we undertake as it would be dry wall specialists that would be needed. We will supply the correct insulation for this application for reducing the noise flow out of the building.

Domestic homes are simple as we have a special application that we adhere to. Are staff are trained to fit two layers of the 135 mm Aerolite to give you maximum benefit.

Sound Proofing Floor Noise from Above

Many older home and flats have wooden floors between then. The noise from above as well as from below is not pleasant. We have had home owners begging for solutions to a problem they did not see coming when purchasing the home. People walking above or your neighbour watching TV. Trying to go to sleep is sometimes impossible.

This is a complicated application that we undertake under certain conditions. The floor must either be lifted in advance or the ceiling below must be removed in advance. This will allow us to insulate the floor space and reduce noise levels dramatically. This will be like a normal home.

However there is a catch if the ceiling is attached to the main beams that are attached to the floor above. You could still have some waling noise to contend with. The reason for this is sound transference. In fact because floor beams in ceiling are attached as one. This is like a doctors stethoscope the sound will travel through all joined sections. Example floor attached to beam attached to ceiling. Noise flow will be stopped with the insulation but walking and banging will follow through.

What is the Solution to This Problem

The ideal application would be to have the ceiling lowered. Having said that no timber with or any part of the new ceiling must touch any part of the beams above. So the new ceiling must be free from any of the above. The the insulation will still be fitted between the floor and you will be happy.

Second application would be if you stay above. Is to lift all flooring then fit 10 mm Sondor rummer approximately 25 mm wide along all beams. We would then install the two layers of insulation and this would reduce the sound from walking quite substantially for the neighbours below.

Reducing Sound Through Windows

Fist price is double glazed window or even triple glazed windows. This will reduce sound from windows substantially. However this is very expensive.

Another more cost effective measure but not as effective. Is to install very heavy acoustic curtains. These curtains will not be bought at your average curtain shop as they will have no idea. The idea is to look for very heavy fabric as well as very heavy linings. The curtain rails must extend past the window more than the norm. In fact make sure that you have rather more curtain than less. As they must have a fan fold when closed.

Noise levels will be dramatically reduced as the curtains will act as a form of acoustic barrier. The cost of these products vary depending on the application.
