How to Choose Designed Ceilings for Different Room Sizes
Choosing the right ceiling design is one of the most critical architectural decisions for any room. A ceiling influences acoustic quality, safety, energy efficiency, and aesthetics. In 2025, architects and designers increasingly turn to metal ceiling systems because they deliver Noise Reduction Coefficients (NRC) ≥0.75, Sound Transmission Class (STC) ≥40, fire resistance 60–120 minutes, and service lives of 20–30 years.
This blog provides a comprehensive guide to choosing designed ceilings for different room sizes, covering small, medium, and large spaces. Technical data, comparative tables, and case studies highlight why aluminium and steel outperform traditional gypsum, wood, and PVC ceilings.
Designed Ceilings for Small Rooms
1. Acoustic Considerations
Small rooms like residential bedrooms or study areas require ceilings with NRC ≥0.78 to prevent sound reflections that cause muddiness.
2. Recommended Materials
- Aluminium panels with micro-perforations for clarity.
- Steel only if fire resistance is critical.
3. Case Study: Amman Residential Apartment
PRANCE aluminium designed ceilings reduced reverberation from 0.8 to 0.45 seconds in a 20 m² bedroom, enhancing speech clarity.
Designed Ceilings for Medium Rooms
1. Acoustic Considerations
Medium-sized spaces such as classrooms, small offices, or hotel suites need NRC ≥0.78 and STC ≥38 to isolate external noise.
2. Recommended Materials
- Aluminium for design flexibility and lightweight construction.
- Steel where fire safety and durability are vital.
3. Case Study: Dubai Business Suite
Hunter Douglas aluminium designed ceilings provided NRC 0.80, improving comfort for corporate guests.
Designed Ceilings for Large Rooms
1. Acoustic Considerations
Large rooms such as theaters, convention halls, or auditoriums demand NRC ≥0.80 and STC ≥40 to ensure even sound diffusion.
2. Recommended Materials
- Steel systems with mineral infill for strength and acoustic isolation.
- Aluminium vaults for curved designs that scatter mid-frequency sound.
3. Case Study: Sana’a Theater Renovation
Armstrong steel designed ceilings increased fire resistance to 120 minutes and maintained NRC 0.79, improving both safety and performance.

Acoustic Performance
1. Aluminium Designed Ceilings
- NRC: 0.78–0.82.
- Lightweight, ideal for small to medium rooms.
2. Steel Designed Ceilings
- NRC: 0.75–0.80.
- STC ≥40, perfect for large rooms.
3. Traditional Materials
- Gypsum NRC ≤0.55, unsuitable for acoustics.
- Wood NRC ≤0.50, aesthetically warm but acoustically weak.
- PVC NRC ≤0.40, ineffective for sound control.
Fire Safety
1. Aluminium and Steel
- Aluminium: 60–90 minutes fire resistance.
- Steel: 90–120 minutes fire resistance.
2. Traditional Materials
- Gypsum: 30–60 minutes, crumbles under fire.
- Wood: Combustible.
- PVC: Melts, releasing toxic fumes.
Aesthetics and Customization
- Aluminium: Powder-coated, woodgrain, or metallic finishes.
- Steel: Large-span, dramatic designs for convention centers.
- Bespoke ceilings integrate smart lighting and branding features.
Case Study: Abu Dhabi Convention Center
SAS International hybrid ceilings combined acoustic steel panels with aluminium finishes, achieving NRC 0.81 while creating a unique branded aesthetic.
Sustainability
- Aluminium: ≥70% recycled, fully recyclable.
- Steel: ≥60% recycled, highly durable.
- PVC: Non-biodegradable.
Case Study: Najaf Green Hotel
Rockfon aluminium designed ceilings cut energy use by 20%, supporting LEED certification.
