Isokern manufactures high-end fireplaces made from the most energy efficient material on earth, volcanic pumice. The Icelandic pumice used in all Isokern components has incredible refractive properties, reflecting heat back into the room instead of absorbing like other site-built concrete, metal and masonry fireplaces.  

An Isokern Fireplace can be installed in less than a day, is less expensive than a traditional masonry fireplace and will last a lifetime. Isokern Fireplaces are available in wood burning and gas, vented and vent free and can be used indoors or outdoors.

Instone offers the complete line of fireplaces and complementary products from firebrick/fireplace stone, to flues and Isoset mortar.
