The Isokern brand, through Earthcore, has revolutionized fireplace construction with a superior material. Clay bricks and metal fireplaces waste precious energy of fuel derived from wood or gas. Isokern has inspired the industry to copy the success of Isokern’s modular technology without the results. Utilizing Icelandic volcanic stone mined from the Hekla volcano, Isokern has achieved vast insulating values in the production of modular component indoor and outdoor fireplaces, wood burning ovens and chimneys for indoor, outdoor, residential and commercial use.
