Fire rating of rock wool sandwich panel

In industrial production, high temperatures in summer are a common challenge, especially for factories and production facilities, where hot weather can not only affect production efficiency, but also lead to safety issues such as fire. Therefore, it is particularly important to take effective fire prevention measures, among which the fire performance of the perimeter protection system is particularly critical. Thermal insulation rock wool sandwich board as a widely used external protection building material, its fire performance is very important, this paper discusses the fire grade of thermal insulation material.

At present, the fire rating of most insulation materials is mainly divided into the following types:

Grade A: non-combustible building materials, mainly suitable for buildings with high safety requirements, almost no burning problems, and can also play a role in stopping the fire. Among them, the thickness of the rock wool sandwich board will affect its fire protection effect, and the thicker rock wool sandwich board can usually provide a longer fire protection time and a higher fire resistance.

B1: refractory building materials, it has a good flame retardant effect, even in the surrounding environment encountered high temperature or open fire, the probability of fire is very low, even if the fire will not spread quickly, there is no fire source will automatically stop.

B2: flammable building materials, its flame retardant effect is smaller than the upper level, in the surrounding environment will burn quickly after the open fire, causing the spread of fire, can not be used with wood columns, wooden beams and other materials, there are certain limitations and dangers.

Grade B3: flammable building materials, it can not prevent combustion, itself is very easy to burn materials, there is a great safety risk in the use of the process, rarely see its figure in the formal building.

As the industry's leading supplier of metal building envelope systems, wiskind's self-developed rockwool sandwich board products, such as COLORPOD ®, COLORGOLD ®, COLORGEM ®, COLORCURTAIN ® Rockwool sandwich board, can achieve Class A fire prevention, effectively avoid fire hazards, and ensure the safety of factories and employees and the stability of production.
