Vermiculite refractory brick, also known as vermiculite insulation brick, is a type of refractory brick that is widely used in the construction industry for its high-insulation qualities and resistance to heat. Vermiculite refractory brick is made from a type of natural mineral called vermiculite that is mined from the earth.

The classification of vermiculite refractory brick is determined by its density, with higher density bricks being used in applications where a higher degree of insulation is required. Vermiculite refractory bricks are typically classified into two grades: lightweight and medium weight. Lightweight bricks typically have a density of less than 900 kg/m³, while medium-weight bricks have a density of between 900 and 1200 kg/m³.





In summary, vermiculite refractory brick is a highly versatile material that has a wide range of applications across many different industries. Its superior insulation properties, resistance to heat, and durability make it an ideal choice for use in furnaces, kilns, and other high-temperature applications. With proper care and maintenance, vermiculite refractory brick can provide reliable and long-lasting insulation for many years to come.
