Ultra slim soundproofing with Tecsound and plasterboard

Tecsound 50 Slim wall Soundproofing - How it works
Where customers have almost no space available for soundproofing we have introduced a new, very slim line solution. We would always recomend the SM20 solution for those who can afford the space. This lack of space is often associated with hallways or where doors / windows are very close to the wall to be soundproofed.

2 Methods are possible
The first uses two layers of Tecsound and two layers of plasterboard. The Tecsound is stuck to the party wall and a  layer of plasterboard screwed to that wall, this is lined with a 2nd layer of Tecsound. A second plasterboard is then added to this. Creating the set up shown above.

Or Slimmer still.
By combining a single layer of 15mm plasterboard with two layers of our high performance tecsound acoustic membrane we believe we have created a cost effective and slim line solution. The solution is relatively simple to install with a layer of self adhesive Tecsound being stuck to the existing wall and a second layer being added to a layer of acoustic plasterboard. The Plasterboard is presented to the tecsound lined wall and then screwed through to the original wall.

This is a brand new and as yet un-lab tested solution.  So we can only go on the feed back of clients, in a domestic environment. Please see the Customer review tab at the top of the page. On the basis of their comments we feel the product is uprating the wall by at least 12/14 db.

The combination of two layers of dense visco-elastic tecsound membrane and the weight of the plasterboard acts as an effective solution for blocking sound across the party wall with absolutely minimal space loss. Where possible adding further mass in the form of another plasterboard layer will enhance this solution.

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

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 such as Tecsound 50. 
  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 Tecsound 50 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-

The Tecsound 50 slim wall provides a moderate level of soundproofing where the space is very tight. It is important to realise that simply putting acoustic plasterboard direct to the wall offers virtually no improvement as you require resilience and absorbancy which in this case is provided by the Tecsound 50. The addtion of Tecsound 50 will help reduce the resonance passing into the plasterbaords.

Understanding Performance
Below 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 performance uplift. 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.

Electrical Sockets

If you are thinking of refitting electrical sockets back into the wall. You might be advised to line your electrical boxes with acoustic putty.

Further Information

Dry lining Plasterboard 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.

The best results for soundstop panels are 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.

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 (45-47db)

So for example after fitting double tecsound and plasterboard your wall could have a 60 db rating, which is an excellent 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.
