Rockwool RW3 100mm between joists
Helps absorb sound inside the ceiling void
Reduces resonance within the timber structure
The acoustic mineral wool is friction fitted between the joists to help reduce sound movement through the ceiling cavity.
Resilient bars fixed perpendicular to joists
Helps decouple the board layers
Reduces direct vibration transfer
The resilient bar layer creates separation between the joist structure and the acoustic plasterboard layers below.
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, the resilient bars should be installed correctly and all perimeter gaps should be sealed carefully.
The Resilient Bar Ceiling System works by adding acoustic 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 bars are then fixed perpendicular to the joists. These bars create a flexible mounting point for the acoustic board layers, helping reduce the amount of vibration passing directly from the joists into the new ceiling surface.
The 19mm Acoustic Plank and 15mm dB Board add mass to the ceiling. 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 are effective, but impact noise can often benefit from treatment at the source as well as below.
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 some vibration transfer through the joist structure. For heavier footstep noise, combining ceiling treatment with floor treatment 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 bars perpendicular to the joists, following the correct spacing and orientation. The acoustic board layers should be fixed to the resilient bars, 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. Avoid rigid bridging around the ceiling edges, light fittings, pipework or other penetrations, as these can reduce the acoustic performance of the system.

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 bar ceiling system is a soundproofing build-up that uses flexible metal bars to separate the new acoustic board layers from the existing ceiling joists.
This separation helps reduce vibration transfer and improves the acoustic performance of the ceiling.
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, although heavy footstep noise may also need treatment to the floor above.
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 bars only, not through into the joists.
If screws bridge through the resilient bar and into the joist structure, the isolation benefit can be reduced because vibration has a direct path through the ceiling.
If the main issue is impact noise, footsteps or vibration from above, treating the floor above can improve results.
A ceiling system can help from below, but impact noise is often best reduced as close to the source as possible.
