HT/ArmaFlex HT-10-99 Sheet Insulation

The HT/ArmaFlex HT-10-99 Sheet is a high-performance, flexible elastomeric foam insulation sheet designed for superior thermal insulation in high-temperature environments. Manufactured by Armacell, this 10mm thick, 1m wide, and 10m long sheet (10m² per roll) is engineered for applications requiring exceptional resistance to UV radiation, heat, and water vapour diffusion. Compliant with EN 14304:2009+A1:2013, it is ideal for insulating large surfaces such as vessels, ducts, and pipes in solar collectors, steam lines, hot gas lines, and industrial installations, both indoors and outdoors.

Key Features

• High-Temperature Resistance: Suitable for continuous operation at temperatures up to 150°C, maintaining flexibility and performance without degradation.
• Low Thermal Conductivity: Declared thermal conductivity of 0.045 W/(m·K) at 40°C, calculated using the formula λ = [39.92 + 0.125·θm + 0.0008·(θm-30)²]/1000, ensuring minimal heat loss and energy efficiency.
• UV and Weather Resistance: Tested to EN ISO 4892-2, offering excellent durability under UV exposure, eliminating the need for additional jacketing in outdoor applications (except in extreme environments).
• Water Vapour Diffusion Resistance: A resistance factor of >3,000 (EN 12086, EN 13469) prevents moisture ingress, protecting installations from corrosion and maintaining insulation efficiency.
• Fire Performance: Classified as D-s3,d0 (EN 13501-1) for sheets, with self-extinguishing properties, no dripping, and no flame spread. Also meets UL 94 V-0 (IEC 60695-11-10) and Class 1 (BS 476 Part 7) standards.
• Easy Installation: Dust- and fibre-free, the HT-10-99 sheet is lightweight and flexible, allowing for quick and seamless installation using ArmaFlex HT625 adhesive (available separately). No special tools required.
• Sustainable and Safe: Free of SCCP and MCCP, with low volatile organic compounds (VOC) per ISO 16000. Meets green building standards including LEED v4.1, BREEAM International, WELL v2, and DGNB.
