1. The panels are different. The rock wool composite board is a new type of insulation material composed of multiple layers of paper sheets and multiple layers of inorganic materials such as glass fiber wool and rock wool. It has excellent fire protection, insulation and sound absorption properties, and has good stability. , will not cause problems such as thermal expansion or shrinkage deformation, and can be directly used in various engineering fields that require thermal insulation; while rock wool boards are simply artificial asbestos boards made from simple rock debris melted at high temperatures and pressed. There is a big difference in use. The former is more suitable for exterior wall insulation systems, while the latter is more suitable for use as filling material in interior decoration or ceiling systems. Relatively speaking, it is rarely used in exterior wall insulation.

2. Different application scopes. Because of its unique structural design, rock wool composite panels have a very wide range of applications. They can be used in exterior wall insulation systems, interior decoration ceiling systems, and ships. High-temperature insulation, building partition walls, fire walls, fire doors and elevator shafts for fire protection and noise reduction in industries such as , metallurgy, and electric power. Although rock wool boards can also be used in exterior wall insulation systems, they are mainly used in exterior wall exterior insulation systems and are limited to exterior wall exterior insulation systems and may not be used in other building insulation systems.

3. Prices vary. The market price of rock wool composite panels is about 200 yuan per square meter. In addition, additional after-sales services can also be provided, such as intimate small-scale steel mesh reinforcement and treatment of important parts. The price of rock wool board is slightly lower, ranging from about 100 yuan/square meter to 160 yuan/square meter. Because of its high water absorption rate, moisturizing measures must be taken to ensure the product life. However, the current national standards The rock wool composite board did not give a clear answer to this question, but only emphasized that apparent density testing should be carried out in accordance with regulations, and the quality of the adhesive should be strictly controlled. Rock wool composite boards are nearly 50% more expensive than rock wool boards. In a sense, rock wool composite boards are an upgraded version of rock wool boards. Of course, both have reached national standards in terms of efficacy and are Class A non-combustible materials. , in line with the Class A non-combustible material standard of the "Combustion Performance Classification of Building Materials and Products" published by the Ministry of Public Security Gongtongzi [2009] No. 46.
