Acoustic Ceiling

What is an acoustic ceiling?

An acoustic ceiling is the sound-absorbing version of a suspended ceiling. Unlike a standard suspended ceiling, the panel face, fill and mounting gap are designed to absorb sound waves. Because the ceiling forms a major part of a room's reflective surface, an acoustic-ceiling intervention alone can dramatically lower RT60.

Which ceiling types are available?

• Mineral-fibre acoustic ceiling: classic 60×60 modular — common in offices and education
• Rock-wool acoustic ceiling: high NRC, top-class fire resistance
• Metal acoustic ceiling: perforated aluminium + acoustic fill, premium look
• Wood acoustic ceiling: warm look, restaurant/hotel
• Suspended baffle (vertical): vertical panels in tall industrial spaces
• Cloud panel (horizontal floating): decorative solution for modern offices and atriums
• Wide-span strip ceiling: linear structure for aesthetics

NRC values and performance

• NRC 0.70 — acceptable minimum (insufficient for high-density spaces)
• NRC 0.80 — suitable for office and education
• NRC 0.90+ — critical acoustic spaces (call centre, education, library)

Where is it preferred?

• Open-plan office and meeting room
• School, university, library
• Hospital corridors, waiting areas
• Pharmacy, retail, store
• Swimming pool (special humidity-resistant products)
• Restaurant, café, hotel lobby
• Industrial production lines (with suspended baffles)

When are cloud panels and baffles used?

For high-ceiling spaces (above 4 m) or where the existing suspended ceiling cannot be changed, suspended solutions are preferred. Cloud panels hang horizontally; baffles vertically. The natural air gap is large here and low-frequency performance increases. In our practice, baffles are the standard solution for factories and atriums.
