Steel Acoustic Louvers

---

Overview

Steel acoustic louvers are engineered systems designed to provide effective ventilation while significantly reducing noise transmission. They are widely used in buildings and industrial facilities where mechanical equipment noise control is critical without compromising airflow.

GSK Global FZC L.L.C. offers high-performance acoustic louver systems manufactured in steel, combining robust structural design, superior sound attenuation, and weather resistance, suitable for demanding environmental and industrial applications.

System Description

Acoustic louvers consist of specially designed aerofoil blades integrated with sound-absorbing materials, allowing air to pass while attenuating noise.

Blade Construction:

• Double-skin steel blades with internal acoustic infill

Acoustic Media:

• Mineral wool / rock wool insulation with protective facing

Airflow Path:

• Designed to create a labyrinth effect to reduce sound transmission

Frame System:

• Heavy-duty steel frames for structural stability

Material & Finish Options

Materials:

• Galvanized Steel (GI)
• Powder-Coated Steel
• Stainless Steel (SS304 / SS316) for corrosive environments

Finishes:

• Polyester powder coating (standard RAL colors)
• Fluorocarbon / PVDF coating for façade applications
• Hot-dip galvanizing for long-term durability

Key Performance Features

Acoustic Attenuation:

• Typical sound reduction: 8 dB to 25 dB+ (depending on depth and design)

Airflow Efficiency:

• Optimized free area to balance ventilation and sound control

Weather Resistance:

• Designed to prevent water ingress with integrated drainage profiles

Durability:

• Suitable for harsh environments and continuous operation

Fire Resistance (Optional):

• Use of non-combustible acoustic infill materials
• 
  

Design Parameters

Louver Depth:

• Typically, 150 mm to 600 mm+ depending on acoustic requirement

Blade Pitch & Angle:

• Optimized for airflow vs sound attenuation performance

Face Velocity:

• Designed as per HVAC and ventilation requirements

Pressure Drop:

• Engineered to maintain acceptable airflow resistance
