Agni Fiber Boards (P) Ltd is manufacturer of high temperature structural insulation boards, mold platen insulation boards & thermal insulation boards for various industrial applications.

Agni Fiber Boards provides a variety of non-asbestos calcium silicate structural insulations that combine high strength and excellent thermal insulating characteristics for use in a variety of heat processing, fire protection and electrical resistance applications.

Our boards provides excellent thermal shock resistance as evidenced in its typical use as a direct contact board for non-ferrous metals and in fire training burn rooms. They are fire resistant to temperatures approaching 600C( 1112F). They also exhibit low thermal conductivities that remain relatively constant over a broad range of operating temperatures.

Our Boards are designed to serve as a backup insulation for any refractory construction, such as insulating fire brick, dense refractory brick, castable, gunning mix, plastic refractory or ceramic fiber.

Agni insulation boards are specifically formulated for oven and furnace insulation. This insulation board is available in 3 grades (Agni400, Agni-500, Agni-600 ) to suit thermal and mechanical strength requirements for various applications.

Inside chambers of the ovens are covered with insulating materials having very low thermal conductivity and good structural strength so that heat losses are less and total power consumption of the ovens can be minimized

It can be selected for oven insulations according to continuous operating temperature requirements. New concept of using AGNI BOARDS in place of old concept of using GLASS WOOL has got more benefits.

Specific Applications

  • High volume baking ovens
  • Steam curing chambers
  • Textile drying ovens
  • Paint booths
  • Curing ovens
  • Powder Coating Ovens
  • Ladle covers
  • Boiler baffles
