T90Pro
Advance Acoustic Ceiling Damper System
The T90Pro Advance Acoustic Ceiling Damper System builds on the lightweight T90 by adding an SG-DM612A Vibration Damping Pad between the slab and the frame. This extra resilient layer further isolates the cassette-keel structure, suppressing low-frequency transmission and raising performance to STC 45 / Rw 45 dB while keeping the same slim 90–120 mm build-up.
It is the preferred choice where a lightweight ceiling must reach a higher insulation grade without the depth or cost of a spring-hung resilient system.

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.
