Prevent Condensation with ArmaFlex Class 1

An Armacell insulation solution with a built-in water vapour barrier to reduce risk of corrosion under insulation (CUI). Prevents condensation to conserve energy and reduce heat loss. Class 1 fire classification according to British Standards (BS476 Part 7). Certified by leading international fire safety agencies. Fibre-free flexible elastomeric insulation.


Key features of ArmaFlex Class 1

  • Closed-cell structure - Minimises moisture permeation to ensure long-term protection against corrosion under insulation (CUI). Removes the need for an additional water vapour barrier. 
  • Good fire performance - FM Approved for the entire range of insulation thickness. Certified to conform to safety, reliability, and performance standards of various local fire safety bodies. 
  • Energy-efficient - Low thermal conductivity minimises energy losses to give long term energy savings
  • Safer indoor air quality - Free of fibre and formaldehyde, and GREENGUARD Gold certified for low emissions fo volatile organic compounds (VOC). 
  • Easy-to-install: Highly flexible elastomeric insulation foam that can be installed quickly on irregular shapes and installations in tight spaces.
