Vermiculite brick is a common building material, mainly made of vermiculite powder, cement and some additives. Vermiculite tiles are widely used in construction, metallurgy, chemical industry and other fields because of their excellent thermal insulation and heat preservation properties and high refractory properties.
Good heat insulation and heat preservation performance
Vermiculite tiles have good heat insulation and heat preservation performance, which can effectively reduce the temperature difference between inside and outside of the building and improve the indoor comfort.
Good fire resistance
Vermiculite bricks have high refractory performance, which can withstand high temperature environment and reduce the possibility of fire.
Good Stability
Vermiculite tiles have good physical and chemical stability and are not easy to be affected by moisture, aging and deformation.
Convenient construction
Vermiculite bricks are easy to manufacture and install. Vermiculite bricks can be cut and processed according to the needs, and are suitable for a variety of different shapes of thermal insulation surfaces.
Environmentally friendly, non-toxic, odorless and non-polluting
Vermiculite tiles sheet is a natural inorganic material, which does not contain harmful substances and is harmless to the environment and human body.
Construction
Vermiculite bricks can be used for thermal insulation of walls, roofs, floors, windows, doors, etc. It can reduce energy consumption and improve the energy utilization efficiency of buildings.
