superior sound transfer control
Celbar cavity fill sound insulation provides superior sound transfer control demanded by designers, owners & occupants. Older properties with ornate ceilings benefit with Celbar acoustic cavity fill insulation blown into the ceiling void reducing noise from rooms above. It is blown into the void through small holes cut into flat areas of the ceiling and repaired afterwards or if major refurbishment is taking place it is filled from above by lifting floorboards.

A simple wall construction of 63mm thick metal studs lined with 12mm plasterboard on each side was tested:
[a] with no sound control material used – Result 31 STC
[b] with mineral wool sound barrier batt – Result 33 STC
[c] with 38mm of sprayed Celbar – Result 49 STC
ultimate soundproofing with Iso-Mount
Celbar is used as a cavity filler in walls and between floors either in conventional rigid constructions or with isolated ceiling systems e.g. combined with one of our Oscar Iso-Mount range for ultimate ceiling soundproofing performance.
For the ultimate soundproofing solution use in conjunction with one of our Oscar Iso-Mount space saving acoustic hanger range.
what our customers say
“Once again thank you for your prompt response with processing our order for the additional Iso-Mounts. The owners took us by surprise when they asked for the additional area to be done, but they have been so impressed with the results of all the acoustic ceilings that they felt they just had to have it done.”
Derrick Murphy, D&M Murphy Plastering Contractors – Oscar Iso-Mount Type 1 Soundproof Ceiling
“The architect’s solution of fitting high level ‘sound absorbing’ panels produced a negligible improvement. We continued to ‘battle’ with intolerable ‘echo’ making the room unfit for its-purpose.
Following an independent sound monitoring exercise an alternative acoustic dampening application was recommended. Sonaspray was selected. My caretaking staff were greatly impressed by the attention to detail paid by your engineers in the installation procedure. Every surface was carefully covered and the procedure was very professionally completed.
The effect of the application has been tremendous! The hall is a different room and PE, assemblies and lunch-times have become pleasurable occasions compared to the sonic battleground we experienced previously.”

“Yotam Ottolenghi used Oscar Acoustics to render shiny surfaces softly spoken.
Oscar Acoustics are very proud to have been mentioned in the Evening Standard, for the superb acoustic result achieved in the beautiful restaurant NOPI by using our exceptionally smooth Oscar Elite acoustic plaster. Fay continues…
It’s time to talk about noise in restaurants… I don’t always – just sometimes – harp on about the unpleasantness of sound ricocheting off unforgiving surfaces, thumping music shivering your timbers and having to give up on the idea of conversation with dinner. Hiring an acoustic engineer when a new restaurant is planned is an expensive move but two of the most successful operators I know make it top of their list of priorities.”

“Soundproof ceiling is complete… I’ve tested it by powering up a loud DeWalt router in the garage and seeing how loud it is in the room above.
WOW. Can hardly hear it… It really was much quieter than I thought it would be. I can finally use the workshop in the evening when the kids are asleep in the room above. I’ll admit not having done it before I was unsure if it would deaden the noise enough for power tools…but I am blown away by how well it works. Thanks again for your help – much appreciated.”
James Burrows, Home DIY installer – Oscar Iso-Mount Type 2
“The whole transaction has been simple and easy. I fitted the ceiling this weekend and it’s made an instant difference. So much so, that I had to ask the owner of the flat above if he had been using the room above.
I will recommend the product to my friends and will use it on other ceilings in my flat. Keep up the good work.”
Jim Hood, Home DIY installer, Oscar Iso-Mount Type 1 Soundproof Ceiling
“We are pleased to confirm that we have used SonaSpray to good effect in a large sixth form college dining hall in Leicester.
Previously, the hall with its hard, highly reflective surfaces, was an uncomfortable space with high noise levels and poor speech quality/intelligibility. The Introduction of SonaSpray to the ceiling and certain wall panels has reduced the reverberation times, significantly reducing noise levels and improving speech quality. The nature of the material and its application have enabled us to follow and retain the existing plaster moulded features of the ceiling and walls.”
