Stud Wall Kit 100mm DFM

Soundproofing system for existing and stud walls that require increased sound insulation compared to standard wall construction. The system comprises high-density acoustic insulation slabs, soundbreaker bars, Noisestop 1+ panels, 15mm acoustic plasterboard and acoustic sealants. By soundproofing the internal walls in your home or workplace, you will stop unwanted airborne and impact/vibration sounds.

System Features

• Acoustic insulation – Slabs are supplied 100mm x 1200mm x 600mm at 60kg density. Reduce airborne sounds resonating inside the stud frame. Acoustic insulation reduces the sound by converting the sound from a sound wave into heat. The high mass also blocks sound transmission.
• Soundbreaker bars – Attach acoustic hangers to the stud frame at 600mm centres to decouple the stud wall from the plasterboard, reducing vibration through the wall. Isolating the stud frame from the plasterboard is integral to lowering sounds that typically vibrate through the timber wall.
• Noisestop 1+ Panels – 18mm thick panels that combine acoustic plasterboard bonded to a 10kg mass loaded vinyl barrier sheet. Adds mass/density to the wall with this combination of materials. The acoustic plasterboard is denser than the standard plasterboard. Mass loaded vinyl reduces sound due to the density and reduces vibration within the plasterboard.
• 12.5mm acoustic plasterboard – Acoustic plasterboard has a higher mass than standard plasterboard, which reduces airborne sounds. Adding more mass will further reduce the airborne sounds.
• Acoustic sealants – Apply acoustic sealant to the edges of the panels where they meet the floor, ceiling and walls. Acoustically sealing the wall will ensure sounds do not leak through small gaps.

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.

Apply the stud wall soundproofing system to new or existing stud walls.

If you are installing the system onto an existing wall, you will have to remove the plasterboard from one side of the wall. Apply Isolation Strips to the perimeter of the frame if you are building a new stud wall.

Reduce potential flanking paths by insulating the floor and ceiling cavity with acoustic insulation slabs.

• Remove the plasterboard from one side of the wall if you are soundproofing an existing wall.
• Use the Isolation Strips around the new stud frame to install a new stud wall.
• Infill the stud cavity with acoustic insulation. Ensure the whole area is filled. Acoustic insulation slabs will friction fit between the studs if you cut them wider than the opening.
• Fit the soundbreaker bars at 600mm centres and approximately 50mm from the floor and ceiling. The bars are attached to the frame by screwing through the pre-drilled holes.
• Attach the first layer of boarding to the bars by screwing through the boards into the wide corrugated flange on the soundbreaker bar.
• Attach the second layer of boarding in the same method, staggering the joints of the first layer where possible.

The diagram shows the layer of mass loaded vinyl pre-bonded onto the acoustic plasterboard to form the Noisestop 1+ Panel. An alternative method of installing the boards would be first to fit the standard acoustic plasterboard and then overboard with the Noisestop 1+ Panel. The sheet of mass loaded vinyl is then between the two acoustic plasterboards. During sound tests, noise reduction is not dependent on where the vinyl layer is within the overall build-up.

NOTE ON FLANKING SOUND – Before installing any soundproofing system, you should consider any flanking paths for the sound. These are areas around the wall where sound will bypass the soundproofing and enter the room. The most common flanking course for sounds would be above or below the wall, which would be through a floor or ceiling cavity. If these areas are constructed from timber joists, you should consider filling the void above or below the area with DFM acoustic insulation to stop potential flanking noise.

• Install onto existing or new stud walls.
• The system’s thickness from the stud wall is 45mm from the stud frame.
• Noise reduction 60dB
• One hour fire rating
• A competent DIYer can carry out the installation

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.
