Wedge AlSi Board | Ceramic Fibre Insulation Board

Buy good quality, high strength, rigid, excellent insulation performance ceramic fiber boards at Wedge. Wedge Ceramic Fibre Boards are manufactured in a wet forming process using ceramic fiber bulk and binders.


To ensure good quality unique shot removing and vacuum forming process is applied. We achieve low thermal conductivity, high temperature stability, uniform density, and excellent resistance to thermal shock and chemical attack. It is designed for insulation applications experiencing vibration, mechanical stress and erosive forces.


Ceramic fiber board can reduce energy costs and cycling times due to high insulating capability, as well as serving to protect refractory surfaces from thermal shock and chemical attack. Available in variety of compositions, densities, sizes and post treatments combinations.

Classification Temperature: 1050ºC, 1260 ºC,1360ºC,1400ºC, 1430 ºC
