Suspended ceiling acoustic systems are a modular ceiling build of acoustic tile panels seated in a T-profile grid. They deliver absorption in the NRC 0.55-0.90 range and room-to-room sound transmission reduction of CAC 35-44 dB. The standard ceiling solution in offices, hospitals, schools and retail — easy MEP access and lighting integration.
What is a suspended ceiling acoustic system?
A suspended ceiling acoustic system is a second ceiling layer built by hanging a T-profile grid from the structural slab and seating acoustic tile panels in the openings. It addresses both room acoustics (NRC) and room-to-room transmission reduction (CAC), and provides rich integration options for MEP, lighting and ventilation.
System components
- T-grid carrier: 24 mm visible or 15 mm slim
- Acoustic tile panels: mineral wool, fibre, cork or gypsum-based
- Hangers and clips: standard 1.2 m spacing
- Vibration isolation hangers (optional): for studios and sensitive areas
- Edge profile (L or tegular): wall connection
Tile types
- Mineral wool tile: NRC 0.60-0.90, the economic standard
- Glass-wool-filled metal tile: industrial, kitchens
- Cork / soft fibre: warm look, NRC 0.55-0.75
- Perforated gypsum: NRC 0.40-0.65, decorative
- Wood wool (Heraklith): NRC 0.60-0.80, natural aesthetic
Performance
- NRC (absorption): 0.55-0.90
- CAC (room-to-room): 35-44 dB
- Plenum depth: 100-300 mm (200 mm recommended)
- Fire class: A1/A2 (mineral tile), BS 476 Class 0
Where it is used
- Offices, towers and call centres
- Schools, universities, libraries
- Hospitals and healthcare facilities
- Stores, malls and retail
- Restaurants and meeting rooms
- Hotel lobbies and conference areas
How is it installed?
First the hanger points are marked from the slab; main carriers at 1.2 m centres, cross carriers at 0.6 m. Tiles are dropped into the grid openings. Critical: to preserve CAC the tile-to-grid junction and wall edge must be sealed; otherwise high tile absorption is undone by inter-room sound bleed.
