Wall Soundproofing - GenieClips Direct

Cross section of GenieClips attached direct to a party wall

To achieve any meaningful soundproofing you have to incorporate a layer of resilience to anything you add to a party wall. Sticking acoustic plasterboard direct to the wall will make very little difference to your soundproofing.

A number of options for party wall soundproofing are available from the very slim line stick on solutions to the thicker and more effective independent stud structures. We are frequently asked if resilient bars or GenieClip® can be added direct to a party wall to save on space. 

In the case of resilient bars, this does not seem to work, while GenieClips do seem to work well when attached direct to a solid party wall. We believe this is due to the much higher level of resilience that the GenieClip incorporates. The vibrations of sound transmission are absorbed much more effectively with rubber than with the metal of resilient bars. In effect the mass of the new soundproofing surface that you are adding is much better isolated than is the case with resilient bars.

A detailed video of this solution can be found on our case study page.

Don't forget to soundproof your plug sockets too. You can find out more in this article.

Dry lining Soundproofed Walls to a smooth finish ready for decoration.

We are often asked what is the final finish and do I need a plasterer? We provide all the materials necessary to achieve a smooth decorate-able finish. Please see video to the right on dry-lining. The wall you end with will be similar in appearance to the video. We supply the finishing compound that allows you to achieve a smooth wall without plastering. All items are automatically added when you press the blue calculator.

Electrical Sockets

If you are thinking of refitting electrical sockets back into the wall. We would advise the lining of electrical boxes with our acoustic putty. Remember a 1% hole in your soundproofing surface can reduce performance of your soundproofing by up to 10%. Lining your plug sockets will go some way to reducing this leakage.

Sound proofing basics

The key to successful wall soundproofing is the improvement of three elements. 

  1. The Resilience of the wall: Resilience is a fanciful term for the springiness on the wall GenieClips are the best form of resilience we know of. Without this, the addition of the weight in the form of acoustic plasterboards will have will have very little impact.
  2. The mass of the wall: This is normally achieved by adding acoustic plasterboard and high density products. A very common mistake that is made is simply to add acoustic plasterboard directly to a party wall. This will not improve soundproofing.
  3. The acoustic "absorbency" of the wall: We add other materials to break up the passage of the sound wave. In effect, the sounds energy gets absorbed more easily within the wall; here we prescribe the easfit slab.

Understanding Performance

We present a performance table below. Most internet sites refer to total performance of their product which is quite confusing, the performance figure attributed to the product is the performance soundproofing materials combined with that of an average wall. We don't believe that this is very helpful as it is hard to attribute the performance of the product itself.

We give an indication of performance uplift. A 10dB of performance uplift should provide a 50% improvement in the performance of the wall. So 20dB would indicate a 50% and then 50% again or A 75% improvement over and above the original wall.

Further information

The best results for any soundproofing system are achieved with solid brick party walls. Breeze block walls may suffer from flanking transmission problems, because of this, any soundproofing treatments require an assessment of this possible flanking transmission problem.

A note on fireplaces: We are frequently asked whether it is necessary to run wall soundproofing around the chimney breast on a party wall? While there is no definitive answer on this question, we are of the opinion that soundproofing the alcoves either side is usually sufficient. This is because chimneys are typically constructed to be fire and smoke proof and are at least of double brick construction, whereas the walls either side, the alcoves, maybe poorly constructed and of single brick. Of course there are exceptions, but in the majority of cases you can reduce your labour and time considerably by just doing the alcoves. Example results based on typical party wall construction of 100mm brick wall (40-47dB)

For example, after fitting GenieClips direct to wall, your wall could have a 60 dB rating, which is a good level of acoustic privacy. Remember these are average figures across a range of frequencies. In practice all sound proofing works better at higher frequencies. Our solution is designed to be fitted to just your side of the wall. If you can install to the other side (the neighbours side) of the wall you will experience an even greater acoustic privacy. See our case studies
