DB 34/T 1505-2011 "Technical Regulations for the Application of Architectural reflection insulating coatings" stipulates the application technical requirements, construction technology and quality control standards of architectural exterior reflection insulating coatings. The Coating effectively reduces the building surface temperature, improves indoor comfort and saves energy and reduces emissions by reflecting solar radiation and providing thermal insulation. The regulations elaborate on the technical requirements of material selection, surface preparation, painting method, film thickness, etc., and put forward specific guidance on environmental conditions, mass inspection and safe construction during the construction process. The implementation of this regulation aims to improve the energy efficiency performance and construction mass of architectural coatings, promote the application of green building materials, and promote the sustainable development of the construction industry.
