The Oscar Acoustics Iso-Mount Type 1 is a space saving, isolating acoustic hanger for soundproofing ceilings.
Iso-Mount Type 1 acoustic ceiling hanger fills a gap in the soundproof ceiling market. Previously all systems available were fixed to the undersides of joists, involving considerable ceiling height loss which was not acceptable to many occupants.
Iso-Mount Type 1 was designed to screw fix to the side of the timber joists which allowed 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.
Designing with a ‘clean sheet’
- The minimum of ceiling height is lost: as little as 6mm (Less than 1/4inch)
- All the work is done from the room below; no work is required to the floor above.
- The Iso-Mount uses a standard clip-on steel channel that is widely available from several manufacturers.
- The rubber Isolating block is substantial and of a calculated hardness (shore), it sits held in position but is not pressed or clamped into steel brackets: Acoustic on-site testing proved this to be a significant step forward.
- The installation achieves (better than), compliance with British building regs Approved Document E for airborne and impact sound.

Features of the Oscar Iso-Mount
- All soundproof ceiling work can be done without going into the apartment or room above.
- Easier and quicker than installing products on the floor of the room above: when doors, skirting boards etc. must often be shortened and adjusted to compensate for the raised level of floor.
- Appears no different to a standard plastered ceiling once complete.
- Adjustable side of joist fixing allowing minimum ceiling height loss and level ceilings across uneven joists.
- Fast and simple clip together installation.

Acoustic testing results
Independent acoustic testing by MRL Acoustics Ltd (acoustic consultants).
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.

“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!”

Re: Acoustic ceiling, Monks Bridge House Butlers Marston Warwickshire
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 had to have it done.
