non-combustible and fire resistantexcellent thermal insulation property
minimal shrinkage at high temperatures
eco-friendly
Vermiculite fire bricks (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.
Main application: as insulation in reduction cells ,as back-up insulation in all types of furnaces (from carbon baking furnaces to remelting of scrap), replacement fire brick for wood burning or multifuelstoves etc.
