Aluminium Foil Lamination

Aerocell ALU



Aerocell – ALU is a flexible thermal insulation material made from closed-cell, elastomeric nitrile rubber with a Aluminium Foil facing for insulation of ducting/pipes/vessels with superior fire performance. It has very high resistance to water vapour transmission. Widely used for underdeck roofing, pharma & clean room application. Aerocell – ALU is produced in pre- formed sheets and pipe sections. These products meet insulation requirements in diverse fields such as the automobile, air conditioning & refrigeration industry, construction segment, hospitals, pharma industries, hotels and cold storage industries.


  • Best For Clean Room Applications
  • Smooth Surface – less dirt
  • Roof Insulation.
  • Durable and Erosion Resistant
  • Easy To Apply
  • General Thermal Insulation
