[0002] Energy-saving building materials are materials used to reduce energy consumption in buildings. The non-combustibility of building energy-saving materials is an important indicator for evaluating their fire resistance in the event of a fire. The non-combustibility test is to determine the fire resistance of a material by exposing it to specific flame conditions and evaluating indicators such as whether it burns, the burning speed, and the spread of flames.
