Application Summary AI generated

GB/T 21558-2008 specifies the classification, technical requirements, test methods, and inspection rules for rigid polyurethane cellular plastics used as thermal insulation materials in buildings. It applies to prefabricated insulation boards, sprayed-in-place foam, and other forms of rigid polyurethane foam used in walls, roofs, floors, and other building envelope components to improve energy efficiency. This standard is primarily used by manufacturers, construction companies, and quality inspection agencies in China to ensure consistent thermal performance, dimensional stability, and mechanical properties of insulation products.
