Easy Wall Soundproofing with SM20 Panels

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

Don't forget to soundproof your plug sockets too. You can find out more in this article.
Can I upgrade this system further?
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.
Can I upgrade this system further?
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?
