Soundproof ceilings using the AcoustiClip Timber Joist Ceiling System to stop airborne and impact noise through ceilings. This ceiling soundproofing system is the best solution for reducing noise from noisy neighbours or improving privacy in your home. The soundproofing is fitted directly to the existing ceiling, ensuring minimal loss of ceiling height. The AcoustiClips provide the decoupling necessary for effective sound insulation by separating the new ceiling from the existing structure. Acoustic insulation, soundproof panels, and acoustic sealants supplied with the kits provide mass and density, as well as sound absorption, to ensure the best possible soundproofing for your ceilings. This system is a Part E-compliant solution and an excellent option for reducing unwanted noise in your home. DIY-friendly soundproofing kit includes all the components needed to soundproof your ceiling, saving you money compared to buying items separately.
Noisestop AcoustiClip Timber Joist Ceiling Soundproofing System
The Noisestop AcoustiClip Timber Joist Ceiling Soundproofing System is a high-performance solution that significantly reduces sound transfer between floors in properties with wooden ceiling joists.
Whether you’re dealing with noisy upstairs neighbours, impact noise from footfall, or airborne sounds like speech and music, this system creates a floating acoustic ceiling that stops noise at its source.
Using resilient AcoustiClips, the system isolates the ceiling lining from the timber joists, breaking the sound vibration path and dramatically reducing airborne and impact noise. Ideal for use in homes, flats, and conversions, it’s the perfect solution for upgrading existing ceilings or adding acoustic performance to new builds.

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. Decibels Explained.
- Remove the existing ceiling to expose the ceiling joist.
- Fill the cavity between the joists with the 100mm DFM acoustic insulation slabs. If cut larger than the opening, the acoustic slabs will friction fit.
- Screw the AcoustiClip into the ceiling joists. Space the clips across the joists to a maximum of 900mm (every other joist) and 150mm from the edge of the wall. The maximum space between the AcoustiChannel should be no more than 600mm (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 15mm soundboard into the AcoustChannel using 25mm self-drilling screws and then the Noisestop 1 Plus Panel 18mm over the first layer using 50mm self-drilling screws. Leave a 2-3mm gap around the ceiling’s perimeter to reduce noise transfer into the adjoining walls.
- Acoustic sealant is applied between each of the acoustic panels and to the perimeter of the ceiling to ensure an airtight seal.
Finishing soundproof panels
- Taping and jointing -Apply joint tape (paper or mesh) over all joints. Use jointing compound to fill and feather out over the tape.
- Skim Plastering – Apply a thin coat of finish plaster (usually 2–3 mm thick) over the entire plasterboard surface.
- Plasterboard Direct Decoration (No Skim) – Tape and joint as usual. Sand and apply a sealer or mist coat. Paint or wallpaper directly onto the plasterboard.
Spacing the AcoustiClip & AcoustiChannel
- Maximum 600mm centres between the AcoustiChannel
- Maximum 900mm centres between AcoustiClips along the AcoustiChannel
- Maximum 150mm from the centre of the AcoustiChannel and the wall
- Ensure the end of the AcoustiChannel does not contact the wall

Why soundproof ceilings using the AcoustiClip System
AcoustiClip: Decoupling clip that absorbs sounds from vibrating through walls and ceilings. Applied to ceiling joists, stud walls, and directly onto solid wall and ceiling partitions. Sound-isolation clip systems are the best way to reduce sound transfer through direct contact without building an independent structure.
Acoustic insulation: Insulating floor and ceiling cavities is a vital component in blocking airborne sound transfer between rooms. Untreated cavities can act as echo chambers, potentially amplifying sounds. Sound insulation slabs absorb sound waves and convert the energy into heat, reducing sound resonance within the cavity and lowering sound transfer.
Ceiling soundproofing FAQs
You will achieve the highest levels of noise reduction by adding mass, creating separation and increasing the ceiling’s ability to absorb sounds.
- Add mass to ceilings with soundproof plasterboard, which is denser than standard boards. Use acoustic insulation inside ceiling cavities between the joists to improve sound absorption and add even more density. Thin soundproof membranes, such as mass-loaded vinyl, increase the mass of the ceiling and reduce vibration and sound.
- Create a separation between the existing and new ceilings to prevent vibration transfer. Resilient channels or isolation clips are best for creating the separation required to stop vibrations effectively.
- By improving the ceiling’s capacity to absorb noise with acoustic insulation, soundproof membranes, and high-mass products, you will ensure that a new acoustic ceiling will absorb airborne and impact sound.
As with most soundproofing solutions, combining products will ensure the most effective level of sound insulation. Here are some of the most effective products for soundproofing your ceilings.
Effective soundproofing products for ceilings
Acoustic insulation
Use acoustic insulation inside the empty cavity to block airborne noises. Any empty cavity could cause sound to resonate and potentially amplify the noise. When you fill the cavity with a sound-insulation slab, it will block and absorb sound. The best insulation for soundproofing ceilings is 100mm-thick 60kg/m³ slabs of acoustic insulation.
Decoupling clips
Use decoupling clips to absorb vibrations that would otherwise transfer through the ceiling structure and between rooms. Specialist clips like the AcoustiClip act as shock absorbers, absorbing vibration energy and reducing it, thereby reducing the sound.
Soundproof panels
Adding mass is key to effective soundproofing, and soundproof panels bring mass and density, which are vital for stopping airborne sound. Replace standard plasterboard with denser acoustic plasterboard to improve sound insulation. Specialist soundproof panels with mass-loaded vinyl offer even higher levels of soundproofing. The Noisestop 1 Plus Panel, combining soundproof plasterboard laminated to a 10kg/m³ vinyl, will significantly increase the airborne sound insulation of any soundproofing system.
Acoustic sealants
When installing soundproofing, ensure the entire area is airtight to prevent sound from escaping through small gaps or cracks. Acoustic sealant applied between the edges and around the perimeter of the area being soundproofed will maintain the area’s acoustic integrity.
When done correctly with the right materials, ceiling soundproofing is highly effective against most household sounds. It is possible to block TV noise, conversation, and movement sounds across floors, including footfall and moving furniture. With the right solution, you can definitely stop unwanted sounds, either from noisy neighbours or noise in your own home.
The most effective solution for ceilings with wooden joists is the AcoustiClip Timber joist System, and the best option for concrete ceilings is the AcoustiClip Concrete Ceiling System.
You can effectively soundproof a ceiling with a drop in ceiling height of around 70-80mm from the bottom of the joist. Using the ceiling’s existing cavity will save you lots of space, which is why it’s a good idea to remove the existing ceiling. Once the cavity is insulated, you can fit an acoustic ceiling system to the joist with less than an 8cm drop.
Where possible, we would recommend light pendants in a newly soundproofed ceiling. Cutting holes for spotlights, etc, could cause a weak spot in the soundproofing. If you are adding recessed lighting, we recommend using acoustic fire hoods, which fit into the ceiling behind the light.
