Wall System 1 is a soundproofing system that offers good noise reduction against airborne sounds and vibration through solid party walls. The combination of materials supplied within this system adds mass and density and isolates the wall. Acoustic insulation inside the stud frame absorbs sound. Soundbreaker bars enhance the isolation of the wall by de-coupling the soundproof panels from the wall. The panel’s composition of 10kg mass-loaded vinyl and acoustic plasterboard further reduce sound transmission due to the increased mass and absorption of the Noisestop 1+ Panel.

Soundproof systems will effectively block higher noise levels than any individual sound proofing party wall product. Combining various products into soundproof systems ensures a higher reduction across a broader range of frequencies; this ultimately stops higher levels of airborne sounds and vibration.

Wall System 1 Specifications

• System thickness 83mm (including the stud frame)
• Fire rating 30 minutes
• Noise reduction 59dB
• Reduce airborne sounds and vibration through your walls
• Apply onto solid party walls
• Part E compliant solution for separating walls

Noise reduction and decibels – A three dB increase is equivalent to halving the sound level. The higher the value for the airborne sound the better the product performs. The lower the stated figure for impact sound the better the product performs. Read the decibels explained guide for more help.

Wall System 1 can be used in various applications to reduce the passage of sound. Predominantly used in the domestic sector to minimise neighbour noise party walls, it is also suitable for use when looking to soundproof offices and commercial buildings requiring additional sound insulation levels.

Composition of Wall System 1

• Incorporate Wall System 1 onto a stud frame of timber or metal. If you are building a new stud wall, isolate the top and bottom with isolation strips (not included with the kit)
• Fill the cavity of the stud frame with the DFM acoustic insulation slabs to reduce sound resonating inside the void
• Attach the Soundbreaker Bars to the stud. The acoustic hangers isolate the wall from the soundproof boarding, which reduces vibration and sound transfer
• Apply the soundproof Noisestop 1+ Panel layer to increase the mass and density of the acoustic wall. The 10kg mass-loaded vinyl membrane is pre-bonded to the acoustic plasterboard, further increasing the sound dampening performance
• Acoustic sealant is applied between each panel and to the perimeter of the wall to ensure an airtight seal

If space allows, always build a soundproof wall without connection to the existing wall. A small gap of 10mm is sufficient to reduce sound transfer through any physical links. Attaching your new stud frame to the ceiling, floor and return walls will help to minimise points of contact directly with the wall.

Combining soundproofing materials to create a soundproofing system is the best way to soundproof a room. Take a look at the individual components supplied when you buy this solution.

Fitting Wall System 1

• Install a stud frame if one is not already in place.
• Leave a small gap of 10mm from the existing wall. Fasten the stud frame to the floor/ceiling and return walls.
• Fill inside the cavity between each stud with the DFM acoustic insulation slabs. Ensure the slabs are packed tightly between the studs.
• The soundbreaker bars are screwed onto the stud frame. Fix a bar 50mm from the top and bottom and place one every 600mm. Attach the bar to the stud frame by screwing through the pre-drilled holes.
• Attach the Noisestop 1+ Panel to the corrugated section of the soundbreaker bar and leave a 2-3mm gap around the wall’s perimeter to avoid noise transfer. Apply a bead of acoustic sealant to each joint and the edge of the wall.
• If you are reinstating electrical outlets, use acoustic putty pads inside the back boxes.

Wall Soundproofing

Make sure you are getting the right soundproofing for your needs. Understanding the most common types of noise and how to stop them will help you decide the right solution.

Different Types of Sound

• Airborne sounds – Conversation, TV noise and radios are examples of airborne sound. The best way to stop airborne sounds is to add mass/density to the walls or ceilings.
• Impact/vibration sounds – Footfall and moving furniture across a floor are examples of impact sounds. The best way to reduce these sounds is to create separation.

In summary, the best way to reduce airborne sounds is by increasing the mass of the area you would like to soundproof. Reducing impact/vibration sounds is achieved by creating separation within the structure.

Reducing Impact and Airborne Sounds

By following some of these steps, you will ensure you get the best level of soundproofing for your room.

• Mass/Density – Increasing the mass and density of the area you are soundproofing will block airborne sounds from transferring between rooms. You will increase the mass of walls and ceilings using materials such as soundproof panels or high-density acoustic insulation slabs.
• Separation – Incorporating separation within the structure will reduce vibration and impact sounds transferring between rooms. Achieve separation by building independent stud walls and ceilings. If you don’t have the space in the room, you can use acoustic clips and resilient channels to decouple the wall and ceiling.
• Absorption – Use materials that are going to absorb sounds. Acoustic insulation is suitable for sound absorption as it converts the sound waves into heat as it passes through the insulation. Dense mass loaded barriers will also dampen and absorb sound.
