Industrial and mechanical acoustic systems must withstand load, heat, airflow pressure, and vibration while delivering measurable attenuation.
In Saudi Arabia, plant rooms, generator yards, cooling towers, and industrial facilities require engineered acoustic control to meet:
- Saudi Building Code
- Environmental boundary limits
- Project NC targets
- Community noise regulations
We supply and install performance-certified industrial acoustic systems in Riyadh, Jeddah, Dammam, Makkah, and Madinah, designed through spectrum-based engineering.
Acoustic Cladding & Wall Lining Systems
Used in:
- Plant rooms
- Generator rooms
- Mechanical service areas
- Industrial workshops
Material Composition
- Perforated GI / powder-coated steel facing (0.7–1.2 mm)
- High-density mineral wool core (48–96 kg/m³)
- Optional MLV barrier layer
- Backing steel sheet or vapour barrier
- Galvanized structural support framing
Typical Thickness
- 50 mm
- 75 mm
- 100 mm (enhanced low-frequency control)
Acoustic Performance
Build-Up Thickness | Typical NRC | Transmission Reduction |
50 mm absorber | 0.70 – 0.85 | 15–20 dB(A) |
75 mm absorber | 0.85 – 0.95 | 20–28 dB(A) |
100 mm composite | 0.95+ | 25–35 dB(A) |

Vibration-Isolated Equipment Bases
For heavy mechanical equipment.
We install:
- Spring-mounted inertia bases
- Neoprene pad systems
- Floating machine plinths
- Anti-vibration hanger systems
Design targets:
- fn 3–10 Hz
- Static deflection matched to load
- Transmissibility below 10–15%
Applications:
- CHW pumps
- FAHUs
- Cooling towers
- Industrial fans
- Generators
Compliance & Verification
All industrial acoustic systems are aligned with:
- Saudi Building Code
- ISO 1996 environmental criteria
- ISO 7235 silencer standards
- ISO 16283 field validation
- ASHRAE noise guidelines
Where required, we support:
- Post-installation noise measurement
- Boundary compliance verification
- NC level confirmation
Industrial acoustic control must balance:
- Attenuation
- Airflow
- Durability
- Structural integration
Material supply without engineered installation leads to failure.
Coordinated design and controlled execution ensure measurable performance in Saudi projects.
