Airborne performance is an attempt to give the performance of a basic single skin plastered brick wall with SM20 added to it. The airborne improvement figure that is quoted are an idea of what can be expected over a basic starting point of a single skin.

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 SM20 insulation is a highly effective solution. Where the system, as shown in the diagram above, is employed, the performance of the single skin brick wall is increased to in excess of 48dB Dnt, W +CTr which exceeds Part E for party wall sound proofing requirements. This can be improved upon using the alternative upgrades we offer.

Upgrade options

As with many solutions there is the 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 low frequency 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?

Limited space?

Where space is at an absolute premium, a single layer of plasterboard can be applied, ideally upgrade to 15mm if using one layer. This will result in a small loss in overall performance over the basic system, but still a significant improvement over the original wall.

SBx Board Upgrade

These boards are an excellent product designed to reduce the transmission of impact and airborne sound between two spaces. The product is our number one choice when trying to improve the soundproofing from noisy neighbours. SBx can be used for soundproofing walls, floors and ceilings whether constructed from timber, steel or solid substrate, in new builds, conversions, remedial and refurbishment projects.

In general we believe that the SBX board will improve performance above the stated figures above, whilst there is also an improvement in impact sound performance as well.

Product Application

The SM20 Panel is simply glued with our high performance SM20 adhesive. Where the rubber needs cutting or shaping this can be done with a sharp knife or stanley blade.

It is essential that there are no holes in the existing wall. The most common source of noise leakage is where the flooring and ceiling joists are fixed. The wall should be as airtight as is physically possible.

The plasterboards are then bonded to the SM20 panels using the spray adhesive provided. It is important to leave a small gap at the perimeter which should be filled with acoustic mastic.

The insulation is high effective where space is at a premium. Where the system as shown in the diagram above 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.

Installation

The system is straightforward to fit. The high density recycled acoustic 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.

Our delivered solutions come with all the necessary parts to complete a DIY soundproofing job.

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 the video below on dry-lining as the wall you end up with will be similar in appearance to the video. We supply the finishing compound that allows you to achieve a smooth wall without plastering.

The key elements of wall soundproofing

Successful soundproofing of a wall involves improving three key elements.

1. The weight of the wall - This is normally achieved by adding heavy materials like acoustic plasterboard. High density products are important too such as the SM20 acoustic panel.

2. The springiness or "resilience" of the wall - Without this, the addition of the mass will have very little impact. The Sm20 acts as resilience and mass. A common mistake is to just add acoustic plasterboard direct to a party wall. This will have virtually no effect

3. The sound absorption of the wall - Most walls have little in the way of absorbency. The heavy rubber layer of the SM20 solution acts to "trap" the energy of sound 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 soundproofing performance

A great deal of confusion is created on many sites when referencing to performance. The total performance which is normally quoted on the majority of sites refers to the performance of an average wall with soundproofing materials added. The draw back of this is that you don't really know the impact of the soundproofing you are adding.

For this reason we also give an indication of acoustic performance uplift. For every 10dB of performance uplift there is a correspondent improvement of about 50% in the performance of the wall. A 20dB should provide a 75% improvement over and above the original wall.

What to do about plug 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.

What to do with 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 acoustic question, we are of the opinion that sound proofing 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, may be 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 sticking the acoustic panels in 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).

Breeze block walls flanking transmission

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 of flanking transmission.

Extremely helpful

I called Soundstop with lots of questions and the person I spoke with was extremely knowledgeable and helpful. I ended up purchasing soundproofed plasterboards and genie clip system from them
