Q130

Resilient Acoustic Wall Damping System

STC 44OITC 31Rw 44 dB ±5 dB≈ 130 mm

The Q130 Resilient Acoustic Wall Damping System is a high-performance independent wall lining. An SG-DM102 Vibration Damping Mat covers the base wall and SG-WD50 Wall Shock Dampers isolate the cassette-keel frame, creating a resilient, decoupled cavity that stops structure-borne transmission.

Filled with 50 mm mineral / synthetic wool and clad in composite insulation board plus plasterboard, the Q130 reaches STC 44 / Rw 44 dB at around 130 mm - ideal for party walls, studios and cinema rooms that need serious airborne isolation.
