SHP-1 Spring Hangers are designed to isolate suspended sources of both noise and vibration by using high resilient neoprene pads and springs to avoid metal to metal contact. Common Spring Hanger Ceiling system incorporates suspension ceiling studs and gypsum board. Higher sound transmission loss systems can be isolated by the use of steel acoustics panel (e.g. PAC40 & PAC30) or direct attached to piping, suspended fans, suspended mechanical equipment, ductwork, etc.
