Kast-O-Lite 22 Insulating Castable (2200ºF)

Note: This is a variation of Insulating Castables.

Foundry Service & Supplies offers a complete line of high temperature insulating castables (monolithics) rated for use in applications ranging from 2000ºF to 3300ºF. Their light weight and low thermal conductivity reduce both the amount of heat storage and heat transfer producing significant savings in furnace fuel consumption. Lower densities reduce the amount of supporting furnace steelwork required and provide more insulation with a thinner lining. Foundry Service can pre-cast and fire parts and shapes per customer suppliecell namerawings as well.
