  2. Mass-loaded vinyl 10kg/5mm – High mass barrier layer for sound absorption.
  • System thickness 18mm
  • Size: 1200mm x 1200mm (1.44sqm)
  • Weight: 26kg
  • Noise reduction 42dB
  • Fire: thirty minutes

Noise reduction with treatment 4dB

Note: Every 10 decibels(dB) reduction in noise level is roughly perceived as a halving of the perceived loudness. So, for instance, if you have a sound that measures 70dB and it decreases to 60dB, it would sound about half as loud to the human ear.

NOTE: When the acoustic plasterboard panel is installed, the plasterboard layer faces into the room, and the acoustic membrane on the back of the board goes onto the wall or ceiling. This panel is best suited for use with AcoustiClips, soundbreaker bars or timber and metal stud frames to form an acoustic system for walls and ceilings.

The Noisestop 1 Plus Panel works best when installed as part of a complete system for walls or ceilings.

  • Ensure the surface you are applying the panels is in good condition, and do any remedial work on the existing wall to ensure it is flat and secure before you attach the panels.
  • Remove skirting boards and coving and extend electrical outlets. Wall linings, such as wallpaper, do not need to be removed before the installation.
  • Fix the panels to acoustic hangers, stud frames or ceiling joists using standard dry-wall screws. You should use Hammer Fixings, nine per board, to fit the boards directly onto solid walls; alternatively, use the Smart Tack adhesive for flat finished walls, one tin per five boards.
  • Leave a 2-3mm gap around the perimeter of the wall to reduce flanking sound transmission. Once the installation is complete, apply an acoustic sealant to fill the gap.
  • Cut the panels using a hand saw or circular saw.
  • Skim plaster or tape and fill the tapered edge.
  • Upon completion of the soundproofing, reinstate the skirting and coving.
  • If you are reinstating electrical outlets, use acoustic putty pads inside recessed back boxes.

Wall soundproofing FAQs

The best soundproofing method for an existing wall is to add mass, create separation, and increase the wall’s sound absorption ability.

Soundproof panels will add mass and sound absorption to your wall.

A soundproof system combining acoustic products such as the Acousticlip will add mass, sound absorption and isolation to the wall.

Combining the following materials will ensure an acoustic wall, reducing the maximum sound level.

  • Acoustic insulation: Improve the wall’s mass, density and sound absorption capability.
  • AcoustiClip: Decouple/isolate the wall structure, reducing sound transfer between rooms.
  • Soundproof plasterboard: Denser than standard plasterboard, acoustic boards will add more mass to the wall.
  • MLV membrane: Mass-loaded vinyl is widely used in soundproofing solutions to dampen walls and increase the area’s sound absorption.
  • Acoustic sealant: Ensure your wall’s acoustic integrity by filling small gaps with acoustic sealant.
  • Acoustic pads: Seal electrical outlets with acoustic putty pads inside the back box of electrical outlets.

All our soundproofing solutions are finished in a tapered-edge soundproof plasterboard, which allows for either a plaster skim or taping and filling before decoration.

Our soundproof panels all come per bonded with the acoustic membranes bonded to the back of the soundproof plasterboards.

The soundproof systems are finished with an outlay of soundproof plasterboard.

Electrical outlets can be reinstated once the wall has been soundproofed.

Use Acoustic Putty Pads inside the back boxes of the outlets to keep the acoustic integrity of the wall.

Acoustic Putty Pads are available for single and double sockets.

The best solution for your situation will depend on how much noise you are trying to stop and how much space you can lose.

The slimmest solutions are soundproof panels applied directly to the wall.

The Noisestop Silent Panel is only 30mm thick and is the best-performing direct-to-wall board. Soundproof panels will help reduce lower-level airborne sounds transferring between party walls.

The best solution for soundproofing your walls against a noisy neighbour is to use the AcoustiClip soundproof system.

The most popular system is the AcoustiClip Direct System. Affixed directly to the partition wall, there is no requirement for a stud frame. The AcoustiClip Direct System offers significant noise control against noisy neighbours.

You should consider fitting the AcoustiClip Solid Wall Stud System if you have excessively loud neighbours. A stud wall system against the party wall will further increase the soundproofing of the AcosutiClip system.

Like party walls stud walls can be insulated for sound using soundproof panels or complete soundproof systems.

Applying soundproof panels over the existing plasterboard will block lower-level airborne sound from transferring between rooms.

Soundproofing a stud wall with a soundproof system will ensure the best level of sound insulation.

Use acoustic insulation, sound isolation clips, and soundproof panels to make stud walls soundproof.

The most effective soundproof solution for stud walls is the Acousticlip Stud Wall System, which combines all the materials required to stop airborne and vibration sounds from transferring through the wall.

Yes, you can fix things by putting them back on the wall.

Always make sure you choose the correct plasterboard wall fixing if you fix lightweight objects such as pictures.

If you fit heavier objects, such as a radiator or cupboard, we recommend fixing them into the structural wall behind the soundproofing. Sound transfer through this kind of attachment would not diminish the soundproofing. All our solutions have acoustic membranes which wrap around screws to dampen vibration sound through fixtures and fittings.

If you have a chimney breast with side alcoves, soundproofing the chimney is not usually a requirement.

The side alcoves are typically the weakest point in the wall, so your soundproofing should be installed there.
