SOUNDPROOFING WALLS

Earlier houses and flats may have been created with party walls that have little or no sound insulation so normal noise levels can be clearly heard from the other side. Neighbors do not have to be noisy to be a problem and it this type of noise that the new noise regulations seek to address. So normal levels of radio noise and speech should not be heard and hopefully, the following solutions will help you to soundproof your Party wall. Each solution has been combined to help with different levels of noise coming through the Party walls. Your solution will depend on your volume been heard and also how much wall space can be used for the Party wall soundproofing.

A) M20 Wall PanelsM20 Wall Panels

 

This is a simple but effective way to upgrade any masonry party walls, when restricted with space. This solution will take up around 2 inches.

 

The solution consists of 20mm recycled rubber matting and 2 x layers of 15mm sound bloc boards. Solution can be upgraded with a 10kg sound barrier matting, additional layer of sound board and also green glue between the boards.

B) Independent WallIndependent Wall

 

The 2nd most effective soundproofing wall solution, which significantly improves on airborne and impact noise been transmitted between two properties whilst also providing some improvement to thermal insulation. Around 6.5 inches of wall space will be used for this solution.

 

The solution consists of a new timber frame, fitted with an air gap between existing party wall and new timber frame.100mm RS60 Rockwool, sound breaker bars, 19mm sound plank and a 12.5mm sound shield acoustic plaster board. Solution can be upgraded with a 5kg or 10kg sound barrier matting and also green glue.

C) MAXI – Independent WallMAXI – Independent Wall

 

This solution significantly improves on airborne and impact noise been transmitted between two properties whilst also providing some improvement to thermal insulation. Around 6.7 inches of wall space will be used for this solution.

 

This solution consists of a M20 wall panel installed to party wall first then a new timber frame, fitted with an air gap between existing party wall and new timber frame.100mm RS60 Rockwool, sound breaker bars, 19mm sound plank and a 12.5mm sound shield acoustic plaster board. Solution can be upgraded with a 5kg or 10kg sound barrier matting and green glue.

D) Acoustic Geni ClipsAcoustic Geni Clips

 

Genie Clips are engineered for superior acoustical performance, reducing the transmission of airborne and impact sound when used in conjunction wit acoustic rock wool and acoustic plasterboard’s. An innovative and reliable sound control solution, which offers our highest level of sound insulation performance even greater than the Independent wall.

 

The solution consists of a new Timber frame structure installed with an airgap between existing wall and frame work. 100mm RS60 Rockwool is installed between frame and the the geni clips and furring channels are fitted according to specifications.

Solution can also be upgraded with the 5kg or 10kg sound matting and green glue.

Things you should know when considering to soundproof your wall:

  • When soundproofing the party wall, you may in some cases need to soundproof the chimney breast as well.
  • Flanking noise may sometimes play a role with the noise through the party wall – noise coming in via another area.

*Results may vary due to flanking noise and/or structural noise
