Main Technical Content: 1.0.1 In order to implement national building energy-saving laws, regulations, and policies, promote the development of building energy-saving technologies in Hunan Province, and standardize the application of double-component hollow glass microbead thermal insulation coating systems in construction projects, this standard is formulated to ensure project quality, achieve safety and advanced technology, and unify technical requirements. 1.0.2 This standard applies to new, renovated, and expanded civil and industrial buildings, as well as existing buildings under green energy-saving renovation projects that adopt double-component hollow glass microbead thermal insulation coating systems for design, construction, and quality acceptance. 1.0.3 The application of double-component hollow glass microbead thermal insulation coating systems shall comply with this standard and relevant national, industry, and Hunan provincial standards. 2.0.1 The double-component hollow glass microbead thermal insulation coating system is an architectural thermal insulation coating system composed of a double-component hollow glass microbead thermal insulation coating as the insulation layer, a complementary reflective insulation coating surface layer, and other structural layers. For the purposes of this standard, it is referred to as the thermal insulation coating system. 2.0.2 The double-component hollow glass microbead thermal insulation coating is made from hollow glass microbeads and nano-scale aerogels as the base material, mixed with cementitious materials, film-forming agents, and other additives as the A component, and inorganic cementitious materials, water-repellent materials, and foaming agents as the B component. The A and B components are mixed in a certain proportion to prepare the thermal insulation coating. 2.0.3 The reflective insulation coating surface layer is a building exterior decorative coating layer made from a synthetic resin base
