Grade: Graphite Insulating Board


  • The boards can be made in complex shapes and made to print in large sizes. Please contact us for a custom quote.
  • Surfaces and edges can be sealed using our GraphiSeal to reduce porosity and improve oxidation resistance.
  • Boards can have foil added to the surface(s) or layered internally to increase radiant heat retention significantly while reducing issues with furnace contaminant containment.
  • Added foil aids in decreasing pump down times and increasing the longevity of the insulation.
  • Similarly, CFC covering on the boards provide durability, impact and wear resistance.
