The combustion performance grade is divided according to China's "Combustion Performance classification of Building Materials and their products", which reflects the burning behavior of materials under the action of flames and the speed of fire spread. The higher the grade, the better the fire resistance of the material. Rock wool board as a commonly used building insulation material, its combustion performance grade is how much?

Rock wool board is a kind of inorganic fiber material made of natural basalt as the main raw material, because of its excellent thermal insulation, sound insulation, fire prevention and other properties, has been widely used in the field of construction. It not only has excellent thermal insulation effect, but also has high compressive strength and durability.

Rockwool board is clearly classified as A class A, that is, non-combustible material. This means that under normal conditions of use, the rock wool board will not burn, even under high temperature or flame exposure, it can maintain stable performance, will not cause a fire or contribute to the spread of the fire.

As A Class A non-combustible material, rockwool board has significant fire protection advantages in the construction field. First, it can effectively slow the spread of the fire, providing valuable time for evacuation and extinguishing. Secondly, the rock wool board will not produce toxic gases during the combustion process, which helps to protect the life safety of personnel. In addition, the rock wool board also has good thermal insulation performance, which can reduce the damage of the fire to the building.

As one of the best selection of building insulation materials, rockwool board not only has good thermal insulation performance, but also has excellent fire performance, which plays an important role in the field of building fire insulation.
