The DNHS series of hanger features both a metal spring and an LDS rubber element. This provides acoustic isolation against both low and high frequency vibration.
The WHR is a low cost ceiling hanger which still provides 5mm of deflection and is constructed from high quality low dynamic stiffness natural rubber which has natural acoustic isolation properties.
Acoustic isolation hangers are an excellent way of preventing airborne noise from below passing into the building structure, or preventing noise/vibration from the floor above entering the room below.
