How to Soundproof a Party Wall

25th November 2023

Soundproof Brick Party Walls

Soundproof party walls (partition walls) to reduce unwanted noise from a neighbour or improve privacy in your home. The party wall is the dividing wall between properties. Partition walls are typically constructed using bricks or breeze blocks; this building method does little to reduce sound transfer between properties. Our party wall soundproofing guide will show you the best techniques and materials to soundproof a party wall effectively.

Party wall soundproofing techniques

Use these soundproofing techniques to reduce noise transfer through brick or breeze block partition walls.

Adding mass/density – Increasing the mass of the party wall will block airborne sounds; walls constructed with lightweight breeze blocks or a single skin of bricks require additional mass to reduce sound transfer. Using acoustic insulation and soundproof panels will increase the wall’s mass and help control the noise level.

Sound absorption – Standard building materials aren’t designed to absorb sounds like soundproofing materials will. Mass loaded vinyl membranes and sound insulation slabs increase the separating wall’s absorption capabilities, diminishing sound transfer between properties.

Decoupling/isolation – Sound passes through solid structures such as party walls to the other side via vibration; reducing the vibration transfer further increases the wall’s ability to minimise sound transfer. The most effective method of reducing vibration through walls is the AcoustiClip system, a sound isolation clip designed to absorb vibration.

Party wall soundproofing materials

With a wide range of party wall soundproofing materials, we thought it would help if we highlighted the best soundproofing products for party walls. To get the most out of your soundproofing, you should use a soundproof system, a combination of acoustic materials to form a soundproof wall. It may not always be possible to build a soundproof wall due to constraints in the room relating to space loss or doors and windows being on a return wall very close to the edge of the party wall. Fortunately, there are slim solutions for soundproofing a wall.

Systems to soundproof party walls

For the best party wall soundproofing solution, use one of the soundproof systems. Our most popular and effective system is the AcoustiClip Direct System, which offers excellent levels of noise reduction and can be applied directly to the partition wall, minimising space loss. A slim alternative is Wall System 2, the thinnest acoustic wall system available.

AcoustiClip Direct to Wall System

Our most effective direct to wall soundproofing solution, the AcoustiClip Direct to Wall System, fits straight to the wall without needing an additional stud frame. With an impressive noise reduction level of 63dB when applied to a single-skin brick wall, this solution is suitable for homeowners with noisy neighbours who must keep space loss to a minimum. All AcoustiClip soundproof systems combine products with high mass, excellent sound absorption, and the decoupling effect of the AcoustiClip. Supplied in the acoustic kits are the AcoustiClip and AcoustiChannel, acoustic insulation slabs, two layers of soundproof panels, a 15mm soundproof plasterboard, denser than standard board and the 18mm Noisestop 1 Plus Panel. This panel features a 10kg mass loaded vinyl acoustic membrane pre-bonded to the acoustic plasterboard. Additionally, the systems include acoustic sealant tubes to ensure effective acoustic sealing of the boards.

Acoustic Insulation

DFM acoustic insulation slabs are an essential soundproofing material to increase the airborne sound insulation performance of walls, floors and ceilings. Because of its mass, density and sound absorption properties, acoustic insulation is used in soundproof systems inside ceiling cavities, stud walls and floor joists. Available in various thicknesses and densities, we recommend using the 60kg slabs for their acoustic performance.

Party Wall Soundproofing FAQs

The best way to soundproof walls is to use a combination of products in a soundproof system.

Adding mass and density, decoupling the existing structure from the new and increasing the sound absorption capability of the wall ensures the highest noise reduction.

The Acousticlip System is the best solution for soundproofing brick party walls. The AcoustiClip Direct System combines all the elements required to soundproof your walls successfully, making it our recommended party wall soundproofing solution. Upgrade the system using the AcoustiClip Solid Wall Stud System for excessive noise levels.

Wall soundproofing really will stop noise from your neighbour coming through your walls. Stopping every noise type and level is impossible, but you can significantly reduce unwanted sounds using the correct solution.

Our most popular solution is the Acousticlip Direct to Wall System.

If you require soundproofing and space loss to be kept to a minimum, then the best product is the Noisestop Silent Panel.

Competent DIYers can install all of our wall soundproofing solutions. We recommend using local tradespeople if you do not want to fit the soundproofing yourself. Local builders, joiners and plasterers would be the most suitable tradespeople to contact. We can provide full-fitting guides for all our soundproofing solutions.

We recommend soundproofing the alcove areas. You should be able to leave the chimney breast as this area tends to have additional layers of brick which add mass to the area.

Our soundproof products and soundproofing systems are finished with acoustic plasterboard. Once the soundproofing is installed, you can bring the wall up to decorative standards without adding additional boarding. The most common method to finish the walls is to have them plastered. Alternatively, you can tape and join the edges along the tapered edge of the boards before decorating. This means you don’t need a plasterer to skim your wall. Once brought up to a decorative standard, you can use lining paper or paint to decorate the panels.

Yes, you can reinstate electrical outlets to your soundproofed wall. Use acoustic putty pads inside electrical back boxes to ensure the acoustic integrity of the wall. If you are extending wires through the wall for lights, then we recommend sealing the hole using an acoustic sealant.

Lightweight fittings can be secured into the soundproofing. Pictures and mirrors can be attached to the soundproofing.

Party wall soundproofing conclusion

Soundproofing party walls is crucial to creating a peaceful and relaxed environment. By employing effective soundproofing techniques and materials, the nuisance of noise transfer between adjoining properties can be significantly reduced, ensuring a more comfortable living or working atmosphere. Whether through the application of specialised insulation, acoustic panels, or other sound-dampening solutions, addressing sound transmission in party walls can lead to improved privacy and reduced disturbances.
