Nearly 80 years ago, a Danish contractor developed the technology of utilizing Icelandic volcanic stone for the manufacture of fireboxes and chimneys. This unique pumice material separates Isokern systems from all other chimney and fireplace systems. It has very high insulation value while being impervious to the harmful effects of burning wood and coal.
Isokern’s modular system construction of this pumice stone fills a niche in the market where the consumer must either buy a metal prefabricated fireplace which requires air-cooling, or spend the high dollars required to build a solid all brick fireplace. The advantages Isokern holds between these two choices has led it to become the largest modular component fireplace and chimney manufacturer in the world, with factories in Denmark and Virginia.
