Our Ultra Slim Wall Soundproofing

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.

Our two slim line options:

Single Plasterboard

Aprox. 10 dB Airborne Improvement

By combining a single layer of 15mm plasterboard with two layers of the high performance Tecsound 50 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 50 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.

Only 19mm Wall Depth Gain

Double Plasterboard

12 dB - 14 dB Airborne Improvement

To get the highest performance whilst still being slim line we recommend using two layers of Tecsound 50 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 50. A second plasterboard is then added to this creating a double layer of soundproofing. This solution is very much a DIYable project that delivers a good level of soundproofing performance with minimal depth gain.

Just 29mm Wall Depth Gain

How it works

The combination of two layers of dense visco-elastic Tecsound 50 membrane and the weight of the plasterboard acts as an effective solution for blocking sound across the party wall with absolutely minimal space loss.

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 and on the basis of their comments we feel the product is uprating the wall by at least 10-14 dB.

Tecsound 50 Acoustic Membrane

Tecsound SY50 is a self adhesive acoustic membrane with an impressive performance. It is extremely flexible and improves both airborne and impact passage of sound.

It is a high density, polymer based synthetic soundproofing membrane providing excellent acoustic insulation in different construction elements. Because it is self adhesive and very flexible, it is very easy to use, an therefore has numerous applications. Tecsoud SY50 is self extinguishing and fire resistant.

Tecsound Performance

Tecsound Performance

The performance of Tecsound 50 is truly impressive. In fact, it's performance is equivalent to lead of the same surface weight. The Tecsound 50 in a single layer boasts an Rw figure of over 25dB and due its chemical make up it has exceptional damping qualities. It is these qualities that are normally absent from rigid plasterboard type constructions. This resilience means that it compares very favourably to the likes of green glue, as it not only provides great resilience but it also provides high mass. The membrane has reinforcing scrim on one side and when applying the panels it should be facing you.

More information.....


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 "absorbency" 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 absorbency which in this case is provided by the Tecsound 50. The addition of Tecsound 50 will help reduce the resonance passing into the plasterboards.


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 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.


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.


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.


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. 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.
