T/ZZB 2809-2022 "Reflection Thermal Insulation Textured Coatings for Buildings" specifies the technical requirements, performance indicators, test methods and application specifications of reflection thermal insulation Textured Coatings, which are applicable to the decoration and thermal insulation protection of building exteriors. The Coatings effectively reduce building surface temperature, improve energy efficiency and improve indoor thermal environment by reflecting solar thermal radiation and providing thermal insulation performance. The standard details the composition of the Coatings, reflection thermal insulation performance, weathering resistance, adhesion, crack resistance and other key indicators, while the construction process and Environmental requirements are clearly specified. By unifying mass and technical standards, the code provides a scientific basis for the research and development, production and application of building energy-saving coatings, aiming to promote the development of green buildings and improve the energy-saving effect and service life of buildings.
