Isokern Fireplaces: Why Homeowners & Builders Choose Them
If you’re planning a new fireplace or updating an existing space, the Isokern modular fireplace system is one of the most reliable and customizable options available today. Built from lightweight volcanic pumice and engineered for high performance, Isokern fireplaces deliver excellent heat output, design flexibility, and long-term durability — all while offering a more efficient installation compared to traditional masonry.
At All In Stone, we supply a range of Isokern products right here in Vermont, helping homeowners, contractors, and designers choose the perfect system for their project.
Isokern Magnum Firebox
Modular fireplace kit alternative to traditional masonry.
1. Performance & Installation
Lightweight Construction
Isokern fireplaces are engineered with a lightweight modular design that dramatically reduces structural requirements. Because they weigh far less than traditional masonry units, they do not require a concrete or masonry foundation. This makes installation possible in locations where a full masonry fireplace would be impractical or cost-prohibitive.
When installing on wood framing, simply use a Fire-Lite Stand, which allows the entire system to sit safely on a combustible floor—saving significant time, labor, engineering, and material costs while still delivering exceptional performance.
Fast, Modular Installation
Each system arrives in lightweight modular components that stack and assemble quickly, resulting in shorter installation timelines. Compared to traditional masonry, this is a cost-effective alternative that doesn’t sacrifice the look, feel, or performance of a classic wood-burning fireplace.
Venting Options
Isokern also gives you two high-performance chimney options to match the needs of any project.
The first is a traditional masonry flue system that offers true zero-clearance installation and is tested and listed to UL 130HT, the rigorous 2100°F high-temperature standard.
The second option is the Eco-Steel+ system, a lightweight stainless-steel venting solution designed for quick, secure assembly. Listed to UL 103 and rated up to 1700°F, Eco-Steel+ provides a durable, flexible alternative to full masonry construction.
2. Highly Customizable for Any Design Style
One of the biggest advantages of an Isokern fireplace is how easily it integrates with any interior design style.
