Acoustic Wall Systems for Effective Sound Insulation for  Party Walls

Acoustic wall systems or false walls are combinations of products combined to offer the highest levels of wall soundproofing. Reduce high levels of sound generated by noisy neighbours, loud music, shouting and barking dogs. Wall soundproofing systems work in two ways. Increase the mass of the wall and create separation, this effectively increases the sound insulation of the wall.

Wall System 1 Offers High Levels of Soundproofing When Applied to a Party Wall

A thicker solution than soundproof panels, but an overall better level of soundproofing. Wall System 1 is our thickest party wall solution at around 85mm. This system utilises DFM, Soundbreaker Bars and the Noisestop1+ boards. Improve the level of soundproofing by installing this system with a 25mm gap between the existing wall and the new wall. Use this system to stop high levels of neighbour noise through a party wall.

Soundproofing a Bedroom Wall Use Wall System 1 if Possible

Use Wall System 1 to soundproof a bedroom wall if you are being disturbed at night. Background noise levels at night are lower than during the day, which means sound is more audible. Wall System 1 offers the highest level of noise reduction so use when possible to soundproof a party wall in a bedroom.

NOTE: When installing any acoustic wall system you should fix the new acoustic wall to the floor, ceiling and adjacent walls. If you fix the new wall to the party wall it can increase the level of sound transferring into the new soundproof wall.

Flanking Noise How to Stop it

Treating flanking noise is important when undertaking any soundproofing work to a party wall. Sound transferring around a wall can reduce the overall effectiveness of the party wall soundproofing. Using the DFM insulation inside floor and ceiling cavities is the best way to treat this problem. Lifting the floorboards against the party wall and inserting DFM 100/80kgm³ between the joists, coming back from the wall around two feet should reduce any flanking noise issues.
