Isokern modular masonry fireplaces and chimney systems by Earthcore, made from lightweight volcanic pumice. Shop Isokern fireplace kits, masonry chimney components, Eco-Steel air-cooled chimney and accessories from an authorized dealer.

Isokern Masonry Fireplaces & Chimneys

Isokern systems are manufactured by Earthcore Industries from Icelandic volcanic pumice, a naturally insulating material that lets a true masonry fireplace and chimney be built in days instead of weeks, at a fraction of the weight of brick. Isokern fireboxes come in standard and Magnum sizes for wood or gas, indoor or outdoor, and are finished with any brick, stone or stucco. The matching Isokern modular chimney system stacks pumice flue blocks for a masonry chimney, while the Eco-Steel air-cooled chimney offers a lighter metal alternative for framed chases.

Specifying an Isokern system

Firebox size, chimney type and height, and fuel all drive the parts list. Our Isokern product builders organize components in installation order. Call (540) 212-9374 and we will spec the job with you before anything ships.
