Isolating acoustic hanger for the construction of soundproof ceilings (reduces airborne and impact noise) with as little as 5 mm of ceiling height loss.

An Isolating ceiling mount which significantly reduces transmission of noise from the floor above, but only loses as little as 5 mm of ceiling height; all work is done from the room below.

The Oscar Iso-Mount Type1 space saving acoustic hanger is a three-component assembly: the metal 'L' bracket screws to the sides of the joists, a rubber block sits in position on the 'L' bracket and breaks the path of vibration to the third component, a metal saddle that is held in position on the rubber block.

For new builds or retrofits, Oscar Iso-Mounts acoustic hangers are screw fixed to the sides of joists which allows for vertical adjustment and the minimum of ceiling height loss, typically 5–6 mm: just enough for the ceiling boards to not directly touch the joists. The ceiling soundproofing is finished with two layers of 12.5 mm thick plasterboard, which are screw fixed to metal channels or timber batts fixed to the mounts.
