  • Compliance: Compliant with Part E Building Regulations (England, Wales, Northern Ireland and the Republic of Ireland).*
  • Installation: easily fitted around recessed spotlights.
  • Where: when fitting any form of spotlights that are to be recessed into a ceiling or flooring soundproofing system.

To be used in conjunction with spotlights to minimize air leakage through the gaps they create, available in five sizes.

When you are installing a soundproof ceiling with the use of spotlights that are to be recessed into the 'acoustic barrier', it is vital to take whatever measures to ensure the ceiling is as airtight as possible, so not only are the joins of plasterboards filled with acoustic sealant but the recesses that spotlights create will need treating.

Fire and Acoustic Downlighter Covers are the best way to minimise air leakage, and each helps to encase the light without creating a build-up in heat and can be installed from above to solve an already existing ceiling, or from below when creating a new one. They are lightweight, flexible and easy to install, requiring no additional support.

It is essential to minimise the cuts you make in your new soundproofing ceiling, or existing ceiling if you're converting. The more spotlights you introduce into a room, the less effective it becomes.


  • 250mm x 250mm x 100-140mm diameter cut out

  • Suitable for fitting below or above the ceiling in combination with our MuteClip® System and MuteMat® Systems
  • Ventilated to reduce heat build-up. No additional support required.
  • They cover a wide range of mains and low voltage downlighters.
  • Prevents fire from penetrating the ceiling void. In a fire situation, the cover expands internally to fill all the available space with a highly insulating fire resistant char.

We are always looking for the best ways to describe to you the world of soundproofing through introducing guides that range from the basic principles of sound, how to best soundproof surfaces and what to look for, and how to understand acoustic test data, to name a few! We want to help you come to the right decision, so whether this is through the use of our guides or talking to a member of our team - we are here to help!

How to Soundproof a Ceiling

A combination of the following will always result in a much improved acoustic performance.

  • Mass: the addition of more substantial materials to reduce sound energy, for example, added layers combined with soundproof plasterboard.
  • Separation: breaking contact with the surface or surfaces through the use of acoustic isolation clips or stud framing.
  • Damping: the reduction of vibration through the use of flexible, damping materials such as Tecsound.


Whether you're soundproofing an already existing home against neighbour noise,  specifying materials for a clients 'future-proofing' or adhering to acoustic regulations, it is important to select the correct system. One common, and often neglected thought in soundproofing is how to best treat low-frequency noise.  Low frequencies are not just found with industrial machinery or amplified music, but also in the human voice, in the use of soundbars or small Bluetooth speakers, and in impact noises such as closing doors.

Fire and Acoustic Downlight Covers are essential to soundproof ceiling installations looking to create recesses for spotlights, and each spotlight will need to specify the correct size to make sure that you minimise the air leakage effectively. It is important to note here that it does not replace having a non-interrupted soundproof system but offers a way of decreasing the loss of performance.


Specify Fire and Acoustic Downlighter Covers for any projects that require spotlight recesses into ceiling systems. With any concerns or questions on how to install or use these inserts, talk to us about your project on 01937 588 226.

  • Install into the spotlight hole with the larger hole facing downwards by exposing the copper wiring, make sure that it is sitting comfortably on the plasterboard above. You will need to squeeze the Downlighter Cover through the hole, this is perfectly fine with how it is designed to be fitted.
  • Cut off the excess copper wiring below the bend of the wire.
  • Install lighting into the Downlighter Cover
  • Seal any gaps around the downlighter if you have access from the room above to ensure maximum coverage.
