Space saving isolating acoustic hanger for soundproofing ceilings
Sound passes through ceilings and floors as vibrations and sound pressure waves generated by footsteps, music or voices in an upper flat. These penetrate and travel through floorboards, joists and ceilings in the form of vibration and noise. By creating an isolated, floating ceiling using our Oscar Iso-Mount acoustic hangers you will stop the vibration that causes the transfer of unwanted noise from flat to flat.
Our Iso-Mount Type1 screws to the side of the timber joists which allows the absolute minimum of ceiling height loss: just a few millimetres (1/4 inch) to allow the Gypsum ceiling boards not to be in direct contact with the joists.
Typical Iso-Mount applications
House conversion to flats, new build and renovation of houses and flats. Shops, restaurants and other commercial soundproofing applications.
Key benefits of the Oscar Iso-Mount Type1
- The minimum of ceiling height is lost: as little as 6mm (less than 1/4 inch).
- Class leading acoustic performance achieving (better than), compliance with British building regs Approved Document E for airborne & impact sound.
- Height adjustable, allowing for flat ceilings across uneven joists.
- All work is done from room below; no work is required to the floor above
- Uses a widely available standard clip-on steel channel. Saves you money when you purchase steel channel direct from manufacturers for as little as £0.88 per metre.
- Easier and quicker than installing products on the floor of the room above.
- Appears no different to a standard plastered ceiling once completed.
- Fast and simple clip together installation.
Oscar Iso-Mount testimonials
"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."

"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."

“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!”

Maximum loading of an Oscar Iso-Mount is 13.5kg. Spaced evenly at 4 Iso-Mounts per square metre the maximum loading per square metre is 54kg.
Typical loading calculation for 220mm (8.66 inches), deep joists:
|2x layers of 12mm plasterboard at 10kg each||20|
|220mm Celbar void fill at 40kg/cu.mtr||9|
|Metal ‘C’ stud at||1.2|
|4x Iso-Mounts at 37 grams each||0.0148|
Plus: The weight of downlighters, smoke sensors, grills etc. that are to be fixed in the plasterboard. Consult the manufacturers of the plasterboard for fixtures to be fixed directly to the plasterboard. Use fastenings as recommended by the manufacturer.
Note: Celbar is an excellent thermal insulator. Bring this to the attention of your qualified electrician who may have to allow for heavier duty cables and top hat downlight covers. Covers are to be fitted in place following the Celbar installation.
