Vermiculite firebrick (maintain heat within the firebox to assist in energy efficiency and complete combustion)
A vermiculite brick is a good choice for various heating appliance, because they not only hold heat in, but also reflect the heat so that the heating appliance is even more powerful.
We can supply vermiculite bricks with almost any size, pattern or shape. No matter you want a panel to fit the specific dimensions and pattern, or just want a standard size panel with a decorative face, we all can meet your requirement.
Characteristics:
1. Non combustible and fire resistant.
2. Excellent thermal insulation properties and minimal shrinkage at high temperatures.
3. Ideal products to use in the lining of a fireplace/inglenook opening, among other applications, providing fire protection exactly where its needed.
4. Environment friendly, non-toxic and zero radioactivity, non-asbestos.
5. Easy to cut and shape with woodworking tools.
Applications:
1. Vermiculite panels insulate the wall of combustion chamber. They can sustain very high combustion temperatures, which increases efficiency of burning and decreases carbon emissions.
2. Use as heat shields, register plates, and replacement fire bricks for woodburning or multifuel stoves.
3. Use to build a reusable mold box for casting or as kiln shelving.
