ArmaFlex Class O is the professional flexible insulation for reliable and continuous condensation control. Its unique microcell structure makes the product easy to install with no additional vapour barrier required. The combination of a very low thermal conductivity and extremely high resistance to water vapour transmission prevents long-term energy losses and moisture ingress and reduces the risk of corrosion under insulation. The built-in Microban® antimicrobial protection and the excellent fire performance make the product especially suitable for use in public buildings and process industries. The complete AF/ArmaFlex Class O family including pipe supports, ArmaFlex Protect fire sleeves and adhesives offers a complete solution for all areas of application.
