Armaflex Duct Plus Insulation

High-Performance Insulation for Air Ducts

Armaflex Duct Plus is a highly flexible, closed-cell elastomeric foam insulation designed specifically for thermal and acoustic insulation of HVAC/R air ducts. Engineered by Armacell, this premium insulation material ensures optimal energy efficiency, condensation prevention, and noise control, making it ideal for commercial and industrial applications such as offices, schools, hospitals, and more.

Key Features

• Closed-Cell Structure: Provides excellent thermal insulation with a declared thermal conductivity of 0.036 W/(m·K) at 0°C, minimising heat losses and enhancing energy savings.
• Condensation Control: High water vapour diffusion resistance (µ ≥ 7000) prevents moisture buildup, ensuring long-term performance and protection against corrosion.
• Fire Safety: Euroclass B-s3,d0 rating, self-extinguishing, non-dripping, and does not spread flames, meeting stringent safety standards for indoor environments.
• Acoustic Benefits: Reduces structure-borne noise, creating quieter environments in ducted systems.
• Fibre-Free and Dust-Free: MCCP-free, with low volatile organic compounds (VOC), compliant with French, Italian, Belgian, German AgBB, Blauer Engel, and Eurofins Indoor Air Comfort GOLD standards for healthier indoor air quality.
• Flexible and Easy to Install: Available in standard and self-adhesive rolls, suitable for both rectangular and cylindrical ductwork. Use with ArmaFlex 520 adhesive for a durable, long-lasting system.
