Isokern vs. Firerock?

There is no comparison.

  • Isokern fireplaces are made from Icelandic pumice, exclusively from volcano Hekla, where the pumice is absent of organic material, making it the cleanest and purest pumice on Earth.
    Firerock fireplaces are composed of Alabama pumice dirt, concrete, and “other” materials.
  • Isokern was born from Danish technology dating back over 90 years, with 30+ years in North America.
    Firerock is a copycat version with no international exposure or any technology.
  • Isokern is manufactured in a state-of-the-art, automated and controlled facility, where no human hands touch the parts in production.
    Firerock is hand poured into molds, limiting production capabilities, which causes questionable inconsistencies.

  • 80% of every Isokern product is made with pure, environmentally clean Icelandic pumice stone, which makes every component unique, very light in weight and highly insulating.
    Firerock components are mostly concrete from cement, making components 3.5 times heavier, not environmentally friendly, and with no insulating value.

  • Isokern materials provide up to 4x the insulation of standard aggregates.
    Firerock relies largely on heavy concrete mix.
  • Every Isokern product manufactured is subjected to consistent quality control checks, and the entire product line complies with all Building Regulatory Agencies. In addition, the entire product line is certified to UL Standards, CSA standards, as well as EPA Clean Wood Burning Certification.
    Firerock simply has not.


When it comes to your fireplace, choose the company that makes fire better, since 1989.
