Due to the large fires caused by the flammability of exterior wall insulation materials, it is mainly due to the flammability of organic materials, which easily spreads the fire and releases a large amount of toxic gas. Therefore, exterior wall fire-resistant insulation boards can demonstrate excellent fire-retardant properties, thereby gaining more applications. These boards are widely used in various construction fields, primarily for residential, industrial, and public building walls, as well as for roofings of residential buildings, swimming pools, cold storage, boilers, and insulation projects with special waterproofing requirements.

Organic thermal insulation materials are inherently flammable, and even flame-retardant organic materials are not immune to fires. A manufacturer of exterior fire-resistant thermal boards explains that foam plastics burn with large amounts of smoke, which is somewhat toxic and can spread over several kilometers. In contrast, exterior fire-resistant thermal boards are inorganic materials with non-flammable properties, meeting the required fire safety standards. They can satisfy the fire protection needs of any building without emitting toxic gases, making them an environmentally friendly and energy-saving material.
