CM12 – Resilient Ceiling Mount
The CM12 resilient ceiling mount is a structural connection that reduces airborne and impact noise passing through ceilings and floors. It is particularly suitable for the discontinuous construction of floors in apartments, villas & duplexes and any specialised room that requires high acoustic isolation such as cinemas, auditoriums and recording studios.
The CM12 comes in 275g/m2 zinc galvanised or stainless steel.

STRUCTURAL PERFORMANCE
Matrix Industries CM12 ceiling mounts comply with Australian Standard They are capable of transferring structural lateral forces
NOISE REDUCTION
CM12 resilient ceiling mounts were assessed in field tests comparing identical isolated and non-isolated rooms within the same building. The acoustic consultant’s report stated, “The vibration isolation incorporated into the building is working satisfactorily, reducing vibration and structure borne noise within the rooms.”
