AcoustiClip Stud Wall System

AcoustiClip Stud Wall System is our highest performing wall soundproofing system for internal stud walls. It provides excellent reduction against airborne noise as well as reducing vibration through the stud partition wall. The acoustic insulation inside the stud frame will absorb sound and ensure it does not resonate inside the void. The AcoustiClip is fixed to the stud frame and absorbs any vibration, reducing the energy that transfers the sound through solid structures. The AcoustiChannel clips into the AcoustiClip to allow the final layers of the wall to be installed. The Noisestop 1+ Panel and the 15mm Soundblock plasterboard is screwed into the AcoustiChannel. This soundproofing system will stop high audible sound levels and vibrations from transferring through walls.

Soundproof systems will effectively block higher noise levels than any individual soundproofing product. Combining various products into soundproof systems ensures a higher reduction across a broader range of frequencies, ultimately stopping higher airborne sounds and vibration levels.

AcoustiClip Stud Wall System Specifications

• System thickness 77mm (from the stud frame)
• Fire rating one hour
• Noise reduction 61dB
• Reduce high levels of airborne sounds and vibration through your walls
• Apply onto stud partition 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.

AcoustiClip Stud Wall System is used in various applications that require high levels of sound reduction. Use this solution in domestic and commercial applications; use this system to soundproof music studios, cinema rooms, and venues such as bars and restaurants. Install this system in your home if you require soundproofing.

Composition of AcoustiClip Stud Wall System

These materials supplied with the AcoustiClip Stud Wall System

• Incorporate AcoustiClip Stud Wall System onto a timber stud frame.
• Fill the cavity of the stud frame with the DFM acoustic insulation slabs to reduce sound resonating inside the void
• AcoustiClips increase separation within the new structure, reducing vibration from one room to another
• The AcoustiChannel fits into the AcoustiClips to ensure isolation from the stud frame and the new wall
• The Noisestop 1+ Panel incorporates soundblock plasterboard with a 10kg mass loaded vinyl mat, all pre-bonded to make installation quicker and easier than other self-adhesive methods
• 15mm Acoustic plasterboard then goes over the first layer to further increase the mass of the wall
• Acoustic sealant ensures an airtight seal

NOTE – The isolation strips and acoustic putty pads are not supplied as part of the system; you can buy these separately.

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.

Fitting AcoustiClip Stud Wall Soundproofing System

• Incorporate AcoustiClip Stud Wall Soundproofing System onto a timber stud frame. If you are building a new stud wall, isolate the top and bottom with Noisestop Isolation Strips
• Fill the cavity of the stud frame with the DFM acoustic insulation slabs to reduce sound resonating inside the void
• Screw the AcoustiClip into the stud frame. Space the clips vertically at 600mm centres with a row of clips 75mm bottom of the wall and 150mm from the top. The clips should be no more than 1200mm apart horizontally (see the diagram below)
• Clip the AcoustiChannel into the clips, join the lengths of the channel by overlapping them by 100mm and screwing them together with self-tapping or drywall screws
• Screw the Noisestop 1+ Panel into the AcoustiChannel and then the final layer of 15mm Soundblock plasterboard over the top. Leave a 2-3mm gap around the perimeter of the wall to reduce noise transfer into the adjoining walls, ceilings and floors
• Acoustic sealant is applied between each panel and to the perimeter of the wall to ensure an airtight seal
• If you are reinstating electrical outlets, use acoustic putty pads inside the back boxes

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.

How to space the AcoustiClip and AcoustiChannel onto a wall

NOTE ON FLANKING SOUND – Before installing any stud wall 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.

Stud Wall Soundproofing

We want to 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.
