The stability of rock wool board is suitable. Similar integrated exterior wall integrated panels are usually bonded, or industrial equipment analyzed chemically or physically. The structural components are similar or close to each other. Therefore, even in harsh environments, it can also ensure safety. Decorative building materials are not only suitable for engineering buildings of good brick-concrete structure, frame shear structure, steel frame, light-weight house and other types, but also for decorative energy-saving and environmental protection projects of existing engineering buildings, as well as indoor and outdoor decoration.

The joints of rock wool board should be tight and smooth, and the gap between boards should not be greater than 2mm. If the gap is greater than 2mm, it should be filled and polished with insulating tape. The bonding operation of the insulation board should be quick, and the bonding mortar should not be peeled before installation. In the process of rock wool board processing, we must properly grasp the scale, choose suitable tools, achieve our expected goals, and in the processing, calm down, encounter problems, and solve them bit by bit.

The stability of rock wool board needs to pay attention to whether the surface of the floor heating rock wool board is damaged. When you see that the surface of the floor heating rock wool board is damaged, it is recommended not to buy it, which will affect the normal use in the later stage. The surface of the floor heating rock wool board is damaged and cannot play the role of maintaining temperature in the later stage. The performance of the rock wool board is water-absorbing. As we all know, the storage of goods in the warehouse cannot be wet, or it will affect the value of the product, but even in the rainy season, it is difficult for rainwater to affect the products in the warehouse. As the temperature gradually rises, the rainwater on the surface will slowly evaporate.
