Vermiculite board

These fire resistant boards are made of expanded vermiculite and special inorganic binder providing them with high resistance to: AR mark boards - 950 ºC, AS mark boards - 1150 ºC. Vermiculite board offer excellent thermal insulation properties and minimal shrinkage at high temperatures. Non-toxic, environmentally friendly. Vermiculite board can be worked easily with wood working tools. It can be sawn, drilled and sanded.


  • Boards are not harmful to health, they contain no asbestos, glass fibre or ceramic fibre particles. 
  • Resistant to atmospheric CO and CH4 impact as well as to cryolites, fluorides. 
  • The boards are hard and resistant to mechanical impacts and high temperatures.
  • Low thermal conductivity.
  • Easy mechanical treatment: cutting, drilling, milling etc.


  • AR mark boards: in industry, chimney insulation (lining), insulation of hot water containers etc.
  • AS mark boards: in industry, for insulation of high temperature ovens, refractors, lining and insulation of fireplace walls.
