Refractory stone fireboxes and combustion chambers for masonry heaters

? The heart of a high-performing masonry heater
Our refractory stone fireboxes are designed to maximise thermal inertia and enhance combustion. Perfectly suited to custom-built masonry heaters, they provide slow, even heat release by radiation, for unrivalled thermal comfort.

✅ High-performance materials
Made from firebricks and refractory stones selected for their resistance to high temperatures and their heat storage capacity, our fireboxes guarantee long-lasting heat release, even after the fire has gone out.

?️ A solution adaptable to every project

• Traditional masonry fireboxes for maximum customisation
