A high strength vermiculite insulating brick.    Its volume stability and thermal expansion levels make Culite H compatible with normal hot face firebricks. Uses include muffle kilns, pottery and enamelling furnaces backing brick in boilers annealing furnaces, soaking pits, linings for ducts and flues, etc.



40% alumina content mortars of most tradenames.
