Armaflex HT Sheet Insulation Outdoor Solar
Armaflex HT Sheet Insulation is Armacell's high-temperature, UV-resistant closed-cell elastomeric foam in flat sheet format, designed for outdoor solar thermal and heat pump applications where standard Armaflex EVO is not suitable. HT grade withstands continuous operating temperatures up to +150°C and prolonged UV and weathering exposure without additional cladding — making it the correct specification for wrapping vessels, cylinders, irregular shapes and large-diameter pipework on solar collector circuits and outdoor heat pump installations.
Why Armaflex HT Sheet for Solar and Outdoor Applications?
- High temperature rated — continuous operating temperature -50°C to +150°C, suitable for solar thermal applications where standard elastomeric foam would degrade
- UV and weather resistant — resists UV degradation and weathering without additional cladding or jacketing
- Flexible sheet format — ideal for wrapping cylinders, buffer vessels, valves, flanges and irregular shapes that cannot be insulated with pre-formed pipe sections
- Built-in vapour barrier — closed-cell structure with μ ≥ 7,000 prevents moisture ingress and condensation
- Class O fire rated — BS 476 Part 6 & 7, suitable for commercial and domestic solar installations
Applications
- Solar thermal cylinder and vessel insulation
- Heat pump buffer vessel and cylinder wrapping
- Valve and flange insulation on outdoor solar circuits
- Large-diameter pipework and bends on rooftop solar installations
- Duct and equipment insulation in high-temperature plant rooms
