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. This lack of space is often associated with hallways or where doors / windows are very close to the wall to be soundproofed.

By combining a single layer of 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 up rating 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.

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 50acts 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.

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 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 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 the 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.
