ArmaFlex Evo 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.


  • Built in water vapour barrier reduces risk of corrosion under insulation (CUI)
  • Highest system reliability when installed with ArmaFix AF pipe supports and ArmaFlex adhesives
  • Stable thermal conductivity for long term energy efficiency
  • Built-in Microban® antimicrobial protection reduces mould and bacteria growth

Customer Questions
Can this be used outside?
Armaflex is suitable to be used outside with further precautions taken. If the pipes are to be exposed to sunlight they will need two coats of Armafinish 99 to provide UV protection. When used underground, the pressure of soil backfilled on top of the Armaflex will cause compression of the material, which will have an impact on the insulation wall thickness. It is recommended that Armaflex is protected against compression by sleeving the insulated pipe into a rigid soil or waste water drainage...
Can this be buried?
Armaflex Evo can be used on buried pipe as long as it is protected from being compressed by the weight above. To protect the insulation from being squashed we recommend that the insulation is placed within a soil pipe or ducting.
