Resilient Bars - Acoustic Lining System

Resilient Bars

Discover the MF ceiling that’s even quicker and easier to install, and delivers effective soundproofing when you have a low ceiling. And to make ordering your resilient bar acoustic ceiling lining even easier, we’ve created kits that take the hassle out of calculating quantities.

MF ceilings can do a brilliant job of lowering ceilings, hiding cables and pipes, and creating pristine surfaces when the original ceiling is cracked and stained. With the right Acoustic Hangers, Plasterboard and Acoustic Insulation Rolls, you can also create a ceiling that’s brilliant at trapping noise and soundproofing your room. But an MF ceiling needs space, and if your ceiling is already low, you may not have the space to drop it further.

That’s where resilient bar can be hugely effective.

What is resilient bar?

Resilient bar is an alternative acoustic ceiling lining that’s ideal for low ceilings. Unlike MF ceiling, you don’t create a new frame beneath the ceiling, you simply fix lengths of resilient bar across the existing ceiling joists, then fix plasterboard to the bar. The system also works effectively on walls.

Fixed correctly (see below), the bar can help to effectively soundproof a room where an MF ceiling would be impractical.

How to fix resilient bar to ceilings

Fix timber battens across ceiling joists at 400-450mm centres, ensuring you securely fix each batten into the joist, not the existing plasterboard. Then fix the 3m resilient bars to each batten, trimming to length with snips. Fix using drywall screws or self-tapping screws through the pre-drilled lip into the timber joist. Be sure to leave the corrugated section of the bar unfixed – it needs to be able to flex and vibrate slightly, absorbing sound as it does so. Tightly fixing the main corrugated face of the resilient bar will adversely affect acoustic performance.

How to fix resilient bar to walls

Position battens horizontally and fix every 600mm, with the lip at the bottom of the bar so the plasterboard pulls the corrugated section away from the wall.

How to fix plasterboard to resilient bar

Use a high density acoustic plasterboard. A double layer will be even more effective. As you position each board, mark the position of the bars. You’ll need to know where they are throughout plasterboard installation.

Fix the first layer of board to the bar (not the joist or timber batten) with self-tappers. Don’t tightly abut the plasterboard to floors, walls or ceiling – leave a 3mm gap around the edges of the wall to allow the plasterboard some slight movement.

Add a second layer ensuring joints overlap, and be sure to also fix the second layer to the resilient
