ArmaFlex Ultima Continuous Sheet Insulation ArmaFlex Ultima Continuous Sheet Insulation is a high-performance, flexible elastomeric foam that delivers exceptional fire safety, energy efficiency, and condensation control. Engineered with Armacell’s patented ArmaPrene technology, this insulation sheet is ideal for insulating air ducts, large-diameter pipes, vessels, and tanks in HVAC, refrigeration, and process equipment applications. Available in thicknesses from 3 mm to 32 mm, it offers a reliable, sustainable solution for commercial and industrial projects across the UK. Unmatched Fire Safety with Low Smoke Emissions ArmaFlex Ultima sets a new standard for fire safety in technical insulation. Classified as B-s2,d0 under EN 13501-1, the continuous sheets produce minimal smoke in the event of a fire, up to 10 times less than standard elastomeric products. This ultra-low smoke density improves visibility and respiration, extending emergency evacuation time. The material is self-extinguishing, does not drip, and prevents flame spread, making it a trusted choice for safety-critical environments. Superior Thermal and Condensation Control With a thermal conductivity of λ ≤ 0.040 W/(m·K) at 0°C and a water vapour diffusion resistance factor of μ ≥ 7,000, ArmaFlex Ultima ensures long-term energy savings and reliable condensation prevention. Its closed-cell structure minimises the risk of corrosion under insulation (CUI), reducing maintenance costs and downtime. Suitable for service temperatures from -50°C to +110°C (down to -200°C for cryogenic applications with technical support), it performs consistently in demanding conditions. Green Building Compliance ArmaFlex Ultima is designed for sustainable construction, meeting stringent environmental standards such as LEED, BREEAM, DGNB, and Nordic Swan Ecolabel. It has low volatile organic compound (VOC) emissions and is free of bromine, antimony, and PVC, ensuring excellent indoor air quality. The product is accredited with a Type III Environmental Product Declaration (EPD) and is compatible with the solvent-free ArmaFlex Ultima EC0550 adhesive for eco-friendly installations. Easy Installation and Durability Available in standard and self-adhesive formats, ArmaFlex Ultima continuous sheets are easy to cut and install, with a width of 1,000 mm and lengths ranging from 3 m to 30 m, depending on thickness. The self-adhesive version features a pressure-sensitive acrylate-based coating for secure application, though ArmaFlex Ultima tape is recommended for additional sealing. The material is UV-sensitive, so protection against sunlight is advised for outdoor use. With no change in thermal conductivity or fire performance over time, it offers lasting reliability.
