SM20 Soundproofing - How it works

The SM20 panel system is a high performance wall soundproofing solution aimed at those who want good acoustic performance. Unlike other solutions this dense recycled rubber is easy to fit and will provide a reliable soundproofing barrier.

The system is straightforward to fit. The high density recycled rubber panels are simply cut to size and stuck to the party wall covering the whole offending surface. We provide the necessary proprietary adhesive .The wall is finished off by adding two layers of acoustic plasterboard.

If you wish to calculate or buy the materials just click on the blue calculator. Our delivered solutions come with all the necessary parts to complete a DIY soundproofing job. For more detailed instruction simply click on the fitting instruction link.

Sound proofing basics

When soundproofing a wall it is necessary to improve three basic components.

1) The mass of the wall- This is normally achieved by adding acoustic plasterboard and high density products.

2) The Resilience of the wall- This is the springiness of the wall. Without this, the addition of the mass will have very little impact. The Sm20 acts as resilience and mass.

3) The sound "absorbancy" of the wall. By adding different components the sound gets trapped more easily within the wall-

SM20 noise insulation panels take advantage of advances in acoustic control technology to strike a highly effective balance between increasing the mass of the transmission wall via the heavy rubber and heavy plasterboards and introducing a dampening spring element of the rubber mats.

Understanding Performance

To the right you will see a performance table.

The total performance which is normally quoted on most sites refers to the performance of an average wall with soundproofing materials added

We also give an indication of acoustic performanceuplift. Remember that every 10dB of performance uplift corresponds to roughly a 50% improvement in the performance of the wall. So 20dB would indicate a 75% Improvement over and above the original wall.

* Total system performance is an attempt to give the performance based on application to an exiting plastered single skin brick wall. Improvements are over this basic starting point. A correction factor of ~5dB is applied to take account of bass frequencies within total performance.

 

 

 

Can I upgrade this system further


As with many solution there is a possibility of an upgrade to this system for those who wish an even higher levels of soundproofing. By adding SBX boards to this system you will further improve the performance particularly from a bass sound perspective. The SBX board brings an almost unique property in an acoustic board in that it has virtually no resonant properties. Read more -Why the SBX upgrade?

Electrical Sockets

If you are thinking of refitting electrical sockets back into the wall. you might be advised to line your 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.

Dry lining SM20 Wall to a smooth decorate-able finish

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 below 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.

 

Some Important Notes

The best results for the SM20 system is achieved with solid brick party walls. Breeze block walls may suffer from flanking transmission problems so any soundproofing treatments require an assessment of this possible difficulty Flanking Transmission problems.

The insulation is highly effective where space is at a premium as for a small loss in performance a single layer of plasterboard can be applied. Where the system as shown in the diagram to right is employed the performance of the single skin brick wall is in excess of 48dB Dnt, W +CTr which exceeds Part E party wall sound proofing requirement.
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. Due to the acoustic nature of stud walls and timber framed walls we would recommend a different set of treatments when upgrading these walls as described in solution 5 stud wall soundproofing. Example results based on typical party wall construction of 100mm brick wall (38-43dB)

Easier to fit than I thought
Goods arrived on time. Fitting was actually easier than I thought it was going to be. Although there was a fair bit of hassle getting the old skirting board off. We got the SM20 panels up on the first day ( two alcoves). And then did the plasterboards a couple of days later. We are really pleased with the result and acheived what we wanted.

1970\'s Semi Detached
1) Outline the problem? "Our problem is a very deaf neighbour, resulting in us suffering, over a long period of time, from having to listen to the sound of high volume TV programmes, loud voices and banging of internal doors etc through the brick party walls of the adjoining property. We used to have to watch the same TV programme as our neighbour as we could view our mute set and listen easily to the sound from next door !!." 2) Ease of fitting "My husband and his brother (both approaching their 70s in age) fitted the recesses of the adjoining wall with resilient bars, acoustic wool and acoustic plasterboard, and the chimney wall with 52mm SM20 Panels. The whole job took two days and both men found the materials easy to work with and the instructions easy to follow." 3) The end result, did it cope with the problem what can you hear now? "What an amazing difference this has made!! I can now sit in my own lounge and read a newspaper or watch TV in peace, something I haven't been able to do for over 8 years. We no longer know which programme our neighbours are watching or if they have friends or relatives visiting and we feel so relieved to have our lives back again. Now and again there is a slightly muffled TV sound penetrating through to our side of the wall but this is completely bearable and nothing at all like the mental torture we have suffered previously."

Easy to fit and worked
1) Outline the problem? "My party wall had just as well not been there. I could hear my neighbours and their children whenever they raised their voice. They didnít need to shout to be heard. The only problem with their television was we couldn't see the picture otherwise I could have sold my TV .It was becoming really annoying especially at weekends. We could hear almost everything & I mean everything especially at night !! 2) Ease of fitting? "I fitted the soundproofing , and it really is easy .I even did it on my own without help. I just followed the simple instructions supplied and it really was simple. Even cutting the boards was easy as pie. You would not know it was there. That canít be bad especially as I have only ever attempted simple D.I.Y tasks before." 3) The end result, did it cope with the problem what can you hear now? "The results are outstanding. There is no way I'm letting my neighbour know Ive put it up because they will probably be even noisier than before. I can only hear their television when they blast it, plus you can hear it louder from outside the house now! Their everyday noise is virtually none existent unless you turn off the TV and put your ear to the wall, even then itís a quiet mumble. Even at night the noise is really, really difficult to hear, you have to try and hear them now!! A brilliant product with brilliant results and easy to fit .Believe me it works!!!"

Did a good job at supressing sound
The product arrived on time. The gluing part of it was a bit of a hassle as it set really quick and we needed to move a couple of tiles, but I am generally pleased with the results
