When it comes to soundproofing, soundproofing roofs is the most common as many homeowners have noisy neighbours. Sound Proofing is a very complex application, and the three main applications are Soundproofing between walls and soundproofing between floors, and finally, soundproofing the roof. In these applications, it is usually the roof space that needs to be insulated with soundproofing insulation. The fact is most noise pollution will come through the roof, so that should normally be the first step. We stock many different acoustic products for most applications.
SoundProofing Roofs
In the application of Soundproofing roofs, we generally insulate with two layers of Aerolite Think Pink. This product is well known for its acoustic values. A single layer of 135mm Aerolite has an 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 bass sounds, we install higher density layers first and then apply the Aerolite.
In nightclubs and pubs, we will generally fit a high-density insulation layer first for the bass 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 the wall as well as floors. SoundProofing Roofs is the easy option.
I really in these applications, walls should be insulated as well. This is not an application that we undertake as it would be drywall 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. Our staff are trained to fit two layers of the 135 mm Aerolite to give you maximum benefit.
SoundProofing Floor Noise from Above
Many older homes and flats have wooden floors between them. The noise from above as well as from below is not pleasant. We have had homeowners 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 attached to the floor above. You could still have some waling noise to contend with. The reason for this is sound transference. Because floor beams in the ceiling are attached as one, this is like a doctor stethoscope. The sound will travel through all joined sections. Example floor attached to the beam attached to the ceiling. Noise flow will be stopped with the insulation, but walking and banging will follow through.
Installing two layers of 135mm Aerolite Insulation will reduce the noise substantially.
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 insulation will still be fitted between the floor, and you will be happy.
The second application will be if you stay above. It is to lift all flooring then fit 10 mm Sondor rubber approximately 25 mm wide along all beams. We would then install the two insulation layers, which would reduce the sound from walking quite substantially for the neighbours below.
Reducing Sound Through Windows
The first prize is a double glazed window or even a triple-glazed window. This will reduce sound from windows substantially. However, this is very expensive.
Another more cost-effective measure but not as effective. It is to install 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 heavy fabric as well as very heavy linings. The curtain rails must extend past the window more than the norm. Ensure that you have rather more curtains than fewer, 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 varies depending on the application.
