Who We Are
Since 1989, I am proud to be the CEO of Isokern by Earthcore. We have set the standard for modular masonry fireplaces and chimney construction in North America. Architects and designers have favored the highly refractive properties of the Isokern fireplaces, which utilize volcanic pumice sourced from the Mt. Hekla volcano and adhere to Icelandic design principles. Today, the Isokern process has been applied to a number of products offered by Earthcore.
While our products are constantly evolving and improving, our fundamentals remain the same: our brand is built on respect for specification professionals throughout North America, top-notch customer care, and an offering of an incredible variety of applications. Isokern’s materials and proprietary recipes are environmentally friendly, meet all regulatory standards, and exhibit high insulation and refractive qualities. No other company’s products in the fireplace industry come close to delivering as much.
Isokern will always strive to offer the most innovative products possible, in order to make your design dreams a reality. We always strive to make fire, better. With you as our driving force. Thank you.
