Diatomite insulation brick is made of diatomite, the product contains a lot of micropores, it is compared with clay, high aluminum, beads and fiber insulation products, with light weight, high compressive strength, low volume density, small thermal conductivity, energy saving insulation effect and good quality and other advantages. It also has the characteristics of no deformation, no odor, safe and convenient construction. It is the ideal material for wall insulation, heat insulation and compartments. It can not only increase the temperature, shorten the heating time, but also reduce the fuel consumption. And has a good sound insulation absorption effect. It is energy-saving and environmental protection equipment.
