It is often thought that just applying a sheet of extra plasterboard to a party wall is all that is required to solve any noise issues they may with their neighbours. The simple fact is this will not make one iota of difference and will do nothing to improve the soundproofing of the wall that would be appreciated by the ear.
Common types of noise experienced through party walls include loud music and raised voices. Now it has to be said that loud noise will almost certainly always be heard and not likely to be resolved by upgrading the soundproofing of the wall. Loud noise such as continually played music at high volumes or incessant shouting and arguing is an environmental issue and should be addressed by the local authority who have powers to monitor the noise and take action to stop it.
Slamming doors can also be a problem that not only create the obvious airborne noise but also transmit noise through the fabric of the building. This is called flanking noise.. Noise from slamming doors has to be addressed with the installation of slow closing automatic door closers but other normal levels of noise created by neighbours can usually be solved with the application of soundproofing onto the party wall.
And noise at night through a wall is often a problem because noise at night is always more easily heard due to other, more normal background noise being much quieter or non-existent. Even lower levels of noise can be annoying and capable of keeping you awake at night, particularly for light sleepers. It is most unlikely that noise at night through a party wall can be soundproofed entirely but in some cases, it may be possible to reduce the intensity of the noise being heard.
Adding soundproofing products to any wall will entail the loss of a certain amount of room space and for best results, more room space has to be used. If it is possible to lose say just under 6 inches (150mm) of space then an independent stud wall can be fitted and infilled with acoustic mineral and clad with 30mm (2 x 15mm) of high density acoustic plasterboard. If this is too much space to oose then the next best option is to fit 50mm stud directly to the party wall, infill with acoustic mineral wool then clad with 30mm of acoustic plasterboard decoupled with our 15mm deep resilient bar system. This method of soundproofing will take up just under 4 inches of space (100mm).
Again if this is still too much space to lose there are two thinner systems that can be considered being our 50mm M20AD solution and the even thinner 27.5mm QuietPanel solution. However, as mentioned before, these thinner systems will not be as efficient at reducing noise through a wall but can be used when space is at an absolute premium.
