This kind of insulation board is inorganic non-combustible, and it is a relatively new type of building materials that can be the same life as the building. In addition, it can also be combined with bonding mortar, crack mortar, plaster mortar and other materials together to form a green, environmental protection and low carbon energy saving insulation system. STP vacuum insulation bag for this insulation board can play a very good effective protective role. Moreover, there is also a special flame retardant film made of aluminum foil and special flame retardant materials, and we can use a relatively new and unique composite process to manufacture a dense film with high gas resistance and flame retardation.
