ArmaSound Supersilence Duct Liner

Overview of Armacell and the ArmaSound Brand

ArmaSound Supersilence Ductliner is an acoustic insulation material within the ArmaSound range, developed by Armacell, a global leader in flexible insulation and acoustic control solutions. ArmaSound represents Armacell’s dedicated portfolio for industrial acoustic applications, combining noise reduction and thermal insulation performance in a single system.

These solutions are designed for demanding environments such as industrial facilities, HVAC systems, marine and offshore applications, where effective airborne sound absorption and system protection are critical. By integrating acoustic insulation with thermal performance, ArmaSound systems help reduce noise levels, improve operational efficiency, and minimise the risk of corrosion under insulation (CUI), ensuring long-term reliability in modern construction and industrial projects.

Introduction to ArmaSound Supersilence Ductliner

ArmaSound Supersilence Ductliner, part of the ArmaSound range developed by Armacell, is a fibre-free acoustic insulation material designed for HVAC duct systems to control airborne noise. It is manufactured from open-cell elastomeric foam based on synthetic rubber, providing stable sound absorption performance while preventing fibre migration and dust release during operation.

The product delivers high acoustic performance with a Noise Reduction Coefficient (NRC) of up to 0.9 (at 50 mm thickness), ensuring effective noise control across a broad frequency range. It also incorporates Microban® antimicrobial product protection within the material structure, helping to inhibit the growth of bacteria and fungi and supporting improved indoor air quality.

Key Advantages of ArmaSound Supersilence Ductliner

ArmaSound Supersilence Ductliner provides a high-performance acoustic insulation solution with the following key benefits:

• High acoustic performance: Delivers a Noise Reduction Coefficient (NRC) of up to 0.9 (at 50 mm thickness), ensuring effective airborne sound absorption across a broad frequency range.
• High performance per unit thickness: Offers extremely high sound absorption per thickness, allowing reduced insulation thickness compared to conventional materials.
• Antimicrobial protection: Features built-in Microban® antimicrobial product protection, helping to inhibit the growth of bacteria and fungi and supporting better indoor air quality.
• Fibre-free construction: Non-fibrous material eliminates fibre migration and dust release, ensuring a cleaner and safer environment.
• Fire performance: Tested to UL 94 (HB, V-0), with self-extinguishing behaviour, no dripping and no flame spread.
• Environmental credentials: Certified with UL Environment Type III Environmental Product Declaration (EPD), contributing to green building standards such as LEED.
• Vibration damping: High density (140–180 kg/m³) helps dampen duct rattling and vibration during operation.

Applications of ArmaSound Supersilence Ductliner

ArmaSound Supersilence Ductliner is designed as an acoustic insulation material for HVAC ducts, air handling systems and plant rooms. With effective airborne sound absorption across a broad frequency range and high density to dampen duct vibration, it is well suited for noise control in residential, commercial and industrial buildings.

The material can be installed directly inside duct systems without the need for additional protective layers, while maintaining durability and performance even at high air velocities (up to 10,000 fpm).
