ArmaFlex® Class 1

ArmaFlex® Class 1 is a flexible, closed-cell insulation material with high resistance to water vapour, low thermal conductivity and optimized condensation control. It is the ideal insulation for pipes, air ducts and vessels in air-conditioning, refrigeration and process equipment to effectively prevent condensation and to save energy. It also helps to reduce structure-borne noise in service-water and waste-water installations.

Key features

  • Closed-cell structure increases resistance to water vapor
  • Reduce long-term heat gain and reduce energy loss
  • Engineered wall thickness operates with the same line temperature in the same environment
  • Thermal conductivity λ0˚C ≤ 0.034 W/(m · K)
  • Water vapor resistance μ ≥ 10,000
  • Flexible and fibre-free for easy installation
  • Type III Environmental Product Declaration (EPD): Declaration number 4786944121.101.1, UL Environment
