ALFISO Vacuum Formed Boards

ALFISO boards are high performance insulation products manufactured from ceramic fiber (or with alumina fiber) and binders, with ALFISO's unique shot removing and vacuum forming process, provide excellent high temperature stability, extra low thermal conductivity, high compressive strength.

ALFISO boards can be easy to saw, drill and die-cut, used as hot-face or back-up thermal insulation in various high temperature applications in furnaces, kilns etc. Additional hardness and strength can be reached with post treatments. Available in variety of compositions, densities, sizes and post treatments combinations, ALFISO board is one of the most versatile products available to the industry today.
