Description

ArmaSound Supersilence Ductliner is an advanced acoustic insulation material specifically engineered for effective airborne sound absorption, damping, and barrier properties within ducting systems. Crafted from an open-cell elastomeric foam based on synthetic rubber, this ductliner is a superior solution for creating quieter environments in commercial, residential, and industrial buildings. Gitco-sa.com, as an authorized Armacell distributor in Saudi Arabia and Bahrain, provides access to this high-performance product. A key benefit of ArmaSound Supersilence Ductliner is its fiber-free composition, which contributes to better indoor air quality by preventing airborne fibers. It also features built-in Microban® antimicrobial protection, inhibiting bacterial and fungal growth, ensuring a hygienic and durable installation. The ductliner exhibits excellent thermal conductivity, with $\lambda_d \le 0.045 \text{ W/(m·K)}$ at 0°C, adding thermal insulation benefits. It is highly resistant to erosion, cracking, or delamination even at high air velocities (up to 10,000 fpm, ASTM C1071), making it robust for duct applications. The product boasts impressive sound absorption coefficients (αw and NRC), with performance varying by thickness: a 50mm thickness achieves a Weighted Sound Absorption Coefficient (αw​) of 1.0 (Class A) and an NRC of 1.05, demonstrating its “super silent” capabilities. It operates effectively from -20°C to 85°C (0°C for self-adhesive versions) and offers practical fire behavior as a self-extinguishing material that does not drip or spread flames.
