A-Flex Eco Class 1

Product Description

Aflex-ECO is a closed cell flexible elastomeric foam made from Nitrile rubber. This material has low thermal conductivity and high water vapour diffusion resistance. It is CFC/ HCFC free, dust and fiber free. It ensures energy saving in eco-friendly manner. This product meets insulation requirement in diverse fields.


  • Completely closed cell elastomeric nitrile insulation
  • Quick & easy to install with no special tools
  • Flexible, durable & easy to handle
  • Excellent compression strength due to closed cell structure Superior thermal insulation properties over other open or semi-closed cell insulation material
  • Very high moisture diffusion resistance & no cladding is required if installed inside
  • Class 1 fire rating as per BS 476 part 7


Insulation to prevent condensation, reduce energy losses and protection against mechanical damage on HVAC ducts/ pipes, used in Airport, Hospitals, Factories, Offices, Malls, Duct, Chiller System.


Aflex-Eco can be used together with Aerostick adhesives as a complete insulation system.
