T190
Resilient Acoustic Ceiling Damper System
The T190 Resilient Acoustic Ceiling Damper System is a spring-isolated ceiling build-up engineered for demanding airborne sound-insulation applications. SG-CD50 Ceiling Shock Dampers with neoprene-lined steel spring hangers suspend the cassette-keel frame from the concrete slab, breaking the structural sound bridges that carry noise between floors.
A 50 mm mineral / synthetic wool absorption layer fills the 150 mm cavity, while SG-DM452 Vibration Damping Tape isolates every rigid keel-to-board connection. The composite sound-insulation board and finish layer complete a decoupled, high-mass ceiling that reaches STC 44 / Rw 44 dB at roughly 190 mm total thickness.

Acoustic Performance
Sound Insulation Prediction
All STC, OITC and acoustic performance figures are estimated / simulated values (INSUL Sound Insulation Prediction v9.0.22, © Marshall Day Acoustics 2017) intended solely as design references — not guaranteed field performance. Final results depend on site conditions, construction details and installation quality, beyond the control of INSUL.
