Rockwool RW3 100mm between joists
Helps absorb sound within the ceiling void
Reduces resonance inside the timber structure
The acoustic mineral wool is friction fitted between the joists to help reduce sound movement through the ceiling cavity.
Resilient clips fixed to the joists
Furring channels fitted into the clips
Reduced direct vibration transfer
The resilient clip and channel layer helps separate the new acoustic ceiling from the existing joist structure above.
19mm Acoustic Plank
Optional Tecsound membrane
15mm dB Board finishing layer
The layered board system adds mass to the ceiling, helping reduce airborne sound transfer from above.
Acoustic performance can vary depending on the existing ceiling structure, joist depth, floor construction above, flanking paths and installation quality. For best results, clips and channels should be installed correctly and all perimeter gaps should be sealed carefully.
The Resilient Clip Ceiling System works by adding absorption, isolation and mass to an existing timber joist ceiling. Rockwool RW3 100mm is friction fitted between the joists to help absorb sound inside the ceiling void.
Resilient clips are fixed to the joists, then resilient channels are fitted into the clips. This creates an isolated fixing layer for the acoustic boards, helping reduce vibration transfer between the existing structure and the new ceiling.
The 19mm Acoustic Plank and 15mm dB Board add mass to the ceiling build-up. The optional Tecsound membrane can be installed between the board layers for extra acoustic density where higher performance is needed.
This ceiling system can be upgraded by including the Tecsound 50SY self-adhesive membrane between the 19mm Acoustic Plank and the 15mm dB Board. This adds extra mass without dramatically increasing the total ceiling depth.
For stronger impact noise issues, it may also be worth treating the floor above with a suitable floor soundproofing system. Ceiling systems can help from below, but footstep noise and vibration are often best reduced as close to the source as possible.
This solution is suitable for ceilings below bedrooms, flats, offices, living spaces and other rooms where noise is travelling from the floor above.
It can help reduce airborne noise such as voices, TV and music, while also helping with vibration transfer through the joist structure. For heavy footsteps or impact noise, combining this ceiling treatment with a floor system above may provide better results.
Start by preparing the ceiling area and checking the joist structure. Fit Rockwool RW3 100mm neatly between the joists, avoiding gaps and over-compression.
Fix the resilient clips to the joists at the correct spacing, then fit the resilient channels into the clips. The acoustic board layers should be fixed to the channels only, not directly into the joists.
Install the 19mm Acoustic Plank first, then apply the optional Tecsound membrane if required, before finishing with the 15mm dB Board. Seal the perimeter carefully with acoustic sealant and avoid rigid bridging around ceiling edges, light fittings, pipework or other penetrations.

Contact usIf noise is coming from the room above, the floor may also need treatment at source. Floor soundproofing can help reduce footstep noise, vibration and airborne sound before it enters the ceiling structure.
Sound can also flank through surrounding walls, especially in flats, terraced homes and shared buildings. Wall soundproofing can help complete the room treatment where noise is not only travelling through the ceiling.
A resilient clip ceiling system is a soundproofing build-up that uses resilient clips and furring channels to isolate the new acoustic ceiling from the existing joists.
This helps reduce vibration transfer and improves the acoustic performance of the ceiling system.
A resilient bar system uses flexible bars fixed directly to the joists. A resilient clip system uses separate clips and channels, creating a more controlled isolated fixing layer.
The clip and channel system can be a stronger option where additional ceiling isolation is needed.
This system can help reduce airborne noise such as voices, television, music and general noise from the room above.
It can also help reduce some vibration transfer through the joist structure. For heavy footsteps or impact noise, the floor above may also need treatment.
Yes, Rockwool RW3 100mm is an important part of this ceiling system. It helps absorb sound inside the ceiling cavity and reduces resonance between the joists.
It should be fitted neatly between the joists, without leaving large gaps or compressing the material too tightly.
The Tecsound membrane is optional, but it can improve the system by adding extra mass between the acoustic board layers.
If you are dealing with stronger noise or want the higher-performing version of the system, it is worth including.
No. The acoustic boards should be fixed to the resilient channels only, not through into the joists.
If screws bridge through the channels and into the joist structure, the isolation benefit can be reduced because vibration has a direct path through the ceiling.
