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.
Why Choose the AcoustiClip Timber Joist Ceiling System

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.
- Finish the system the way you would finish standard plasterboard. The panels are supplied with tapered edges, which allows for dry lining or plastering.
Spacing the AcoustiClip & AcoustiChannel
- Maximum 600mm centers 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
