The Power of Pumice

How We Make Fire Better.

Our fireplaces are designed for your home, but our company was designed around your needs. After 70 years of unparalleled performance in the construction industry, Earthcore’s Isokern line has become the most trusted modular system in the world. Since 1989, we have proudly provided exceptional products combined with unmatched customer service from our 10 solution centers and dedicated network of over 400 dealers.

Born In the Heart of Mt. Hekla

Extracted from Iceland’s Mt. Hekla volcano, Earthcore products are made from genuine volcanic pumice. Earthcore has exclusive rights to mine this high-grade material from a 25-mile long volcanic fissure and the volcano itself, which rises to a height of 5,000 feet. Estimated at about 7,000 years old, central volcanoes like Mt. Hekla can remain active for around 100,000 years. With durability like that, it’s no wonder our fireplaces are guaranteed for life.

About Us

Pumice - Naturally Better.

Pumice is a natural insulator. This is the unique property that separates pumice from all other chimney and fireplace materials. The insulating properties of Pumice allow the flue gases in the chimney to quickly reach their optimum temperature enabling the heating appliance to reach its optimum performance shortly after lighting. It also keeps the chimney warmer longer as the heat output of the appliance decreases – once again aiding performance and reducing the likelihood of condensation and soot build-up.

Pumice has very little expansion and contraction with temperature change. This reduces the possibility of cracking and structural damage that can occur with other products. Pumice is a natural insulator, able to maintain the temperature of flue gases when other products have allowed the temperature to fall below the dew point.

In 1989 under the direction of CEO Carl Spadaro, Isokern by Earthcore became the standard for modular masonry fireplaces and chimney construction in North America. Utilizing Icelandic design principles and volcanic pumice sourced from the Mount Hekla Volcano, architects and designers favored the high refractive properties of the Isokern fireplaces. As time has passed, the Isokern process has been applied to a number of products offered by Earthcore.

While our products may change, our foundation remains the same – a brand built on respect to specification professionals throughout North America, customer care, and offering an incredible variety of applications that we can attest to. Isokern materials and proprietary recipes are always environmentally friendly, meet all regulatory standards and exhibit high insulation and refractive qualities. No other products in the fireplace industry share this extensive list of qualifications.

Isokern will always strive to achieve the most innovative products possible, in order to make your design dreams a reality. Because that’s how we make fire, better. With you as our driving force. Thank you for your time.
