Our SunPro® Foil Kraft FSK Single Side Aluminium insulation are mainly used as aluminium foil roof insulation, reflective foil wall insulation and also could be applied as finishes onto rock wool, glass wool etc. Our product is used as a moisture vapor barrier facing in air conditioning ductworks and cold rooms. This flexible thermal insulation sheets also service as energy insulating barrier in aid duct and HVAC system.

Product Benefits

  • Eco friendly,environment friendly and radiant barrier.
  • Aluminum foil woven fabric as a radiant barrier stops up to 97% of radiant heat transfer which improves the performance of the insulating material
  • PE woven fabric provides high tensile strength and durability
  • Aluminum foil woven fabric provides an efficient, space saving, and healthy method of temperature control and energy savings.
  • Lightweight and easy handling and low cost waterproof type.
  • Never use chemical bonding materials.
  • PE woven fabric is used; you can sew it and easily install it on big building such a warehouse ceiling, factory building, super market, gm, container liner.
  • For heavier basic weight based on order are also available.
  • Different lengths and basic weight are available.


High reflected rate 97% aluminium foil as outer surface could reflect solar light and block thermal radiant energy; Kraft as liner made it much more stronger than single layer of pure aluminum foil, could be folded into any shape so as to install easily.
