Scope: Nationwide; Main technical content: Due to the disadvantages of glass wool's easy deformation, building curtain walls have long used rock wool as a thermal insulation material. However, the material characteristics of rock wool itself make it have the disadvantages of heavy weight, easy water absorption, high thermal conductivity, inconvenient installation and construction, and easy collapse over time, which affects the thermal insulation effect. This kind of material selection and its limitations and single nature have also brought disadvantages to the use and development of thermal insulation materials for building curtain walls, especially for building curtain walls using rock wool as a thermal insulation material. After solving the problems of insufficient hardness and easy deformation in the traditional glass wool material, hard-coated glass wool boards can become another choice of thermal insulation materials for building curtain walls. Moreover, with its advantages of light weight, good thermal performance, and no pollution, it will become an ideal thermal insulation material for building curtain walls. By formulating the technical specifications for hard-coated glass wool boards, manufacturers can standardize the use of materials and production, ensuring their correct application in design and construction. At the same time, it is also the basis for the compilation and promotion of related technical drawings. It can effectively improve the current disadvantage of single choice of thermal insulation materials for building curtain walls, and enhance the thermal insulation effect and durability of building curtain walls.
