Understanding the Challenge: Why Ductwork Noise Reduction Matters

In modern building management, HVAC systems are not just about temperature control; they are major contributors to indoor environmental quality. Excessive noise from air handlers, fans, and turbulent airflow within ducts can lead to:

• Reduced Productivity: In open-plan offices and call centers, background noise above 45-50 dB(A) significantly impacts concentration and employee well-being.
• Regulatory Non-Compliance: Many jurisdictions enforce strict noise limits for residential areas near industrial zones or for interior spaces in hospitals and schools.
• Customer Experience: In hotels, restaurants, and retail spaces, audible HVAC noise detracts from the premium experience customers expect.

Traditional insulation methods often fail to address low-frequency rumble or high-frequency hiss. Jinzehong leverages advanced material science and precision manufacturing to create solutions that target these specific acoustic frequencies.

Our Ductwork Noise Reduction Solutions

At Jinzehong Wire Mesh Products Co., Ltd., we specialize in manufacturing high-performance acoustic components. Our core products are designed to integrate seamlessly into existing ductwork or be specified during the initial design phase of new HVAC installations.

1. Perforated Metal Acoustic Panels

Our perforated metal sheets are the backbone of many duct silencers and noise enclosures. By precisely controlling the perforation pattern, open area percentage, and hole diameter, we can optimize sound absorption while maintaining structural integrity and airflow efficiency.

• Materials: Stainless Steel (304/316), Galvanized Steel, Aluminum, Copper.
• Perforation Types: Round, Square, Slot, Hexagonal, Decorative patterns.
• Surface Treatment: Powder coating, Anodizing, Mirror polishing (for aesthetic visibility).

2. Sound-Absorbing Liners and Baffles

For direct duct installation, we provide custom-cut acoustic liners made from mineral wool or fiberglass wrapped in our permeable metal facings. These liners absorb sound energy, preventing reflection within the duct.

• Thickness Options: 25mm, 50mm, 75mm (customizable based NRC requirements).
• Fire Rating: Class A / Non-combustible options available.
• Moisture Resistance: Hydrophobic treatments available for humid environments.

3. Custom OEM/ODM Fabrication

Every HVAC project is unique. Our engineering team works with your blueprints to fabricate noise reduction components that fit exact dimensions. Whether you need complex curved baffles or standard rectangular panels, our CNC machinery ensures precision.
