The AcoustiClip Timber Ceiling System offers the highest level of noise reduction in your home. The system minimises airborne and impact sound transmission through timber joist ceilings. Combining the AcosutiClips for decoupling and isolating the ceiling with high mass and sound absorption materials, this soundproof system effectively restores quiet to your home.
The AcoustiClip Timber Ceiling System comprises the following materials.
- AcoustiClip – Isolates the ceiling joist from the soundproof panels, decoupling the new ceiling
- AcoustiChannel – Metal furring channel to attach the soundproof boards
- Acoustic insulation – Adds mass and absorption to reduce airborne sound transfer
- Noisestop 1 Plus Panel 18mm – Acoustic plasterboard 12.5mm with a layer of 10kg mass loaded vinyl membrane to increase mass and dampen sound and vibration energy
- Acoustic plasterboard 15mm – More mass than standard plasterboard
- Acoustic sealant – Ensure acoustic integrity of the wall by sealing edges and gaps
Thermal Resistance R:
- Acoustic plasterboard 12.5 mm = 0.050 m2 K/W
- Acoustic plasterboard 15.0 mm = 0.060 m2 K/W
- Mass loaded vinyl 0.14 m² K/W
- Acoustic insulation 2.90 W/mK
Thermal Conductivity λR:

- Remove the existing ceiling to expose the ceiling joist.
- Fill the cavity between the joists with the 100mm DFM acoustic insulation slabs, acoustic slabs will friction fit if cut larger than the opening.
- 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 Noisestop 1+ Panel into the AcoustChannel and then the final layer of 15mm Soundblock plasterboard over the top. Leave a 2-3mm gap around the wall’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.
Fix an AcoustiClip at the start and the end of each row. Acousticlips can be spaced at a maximum of 900mm centres across the joist (every other).
AcoustiClips are fitted with a maximum of 600mm centres along the joist length.

The best method of soundproofing a ceiling is to use a combination of products in a soundproof system.
Soundproof systems will add mass, increase sound absorption and decouple the existing structure from the new.
We recommend using the AcoustiClip system to soundproof your ceilings. The combination of materials supplied with the AcoustiClip Timber Ceiling System comprises all the required products to sound insulate the ceiling against impact and airborne sounds effectively

Unless you have very high ceilings, you will probably need to remove the plasterboard or lathe and plaster to soundproof your ceiling effectively.
Removing the existing ceiling will allow you to use acoustic insulation inside the ceiling joist, which is a great way to add mass. Using the AcoustiClip system, you will decouple the ceiling, which isolates the joist from the new ceiling.
Removing the ceiling means you can use the AcoustiClip Timber Ceiling System, our recommended solution.
If you are using downlighters in your ceiling, you should fit acoustic/fire hoods over the lights to ensure the acoustic integrity of the ceiling.
Stopping impact sound through the floor above is difficult to stop from below. In an ideal world, you would soundproof the floors to stop the impact sound. If you can’t access the floor, the best solution is to install a ceiling isolated from the existing.
If you have very high ceilings, you could install a completely new ceiling with joists without connection to the existing ceiling. If this option does not apply, you must use a system that isolates the new ceiling even if it is in contact with the joist.
The best solution for achieving isolation is to use The AcoustiClip Timber Ceiling System.
