Partition boards refer to prefabricated wall panels for non-load-bearing parts of buildings as specified in JG/T169-2016 "Lightweight Strip Boards for Building Partition." These include glass fiber reinforced cement boards (GRC), glass fiber reinforced gypsum hollow boards (GRG), aerated concrete boards (ALC), steel-reinforced cement boards, lightweight concrete boards, and composite sandwich lightweight boards, among others. Their full name is Lightweight Strip Boards for Building Partition, and they serve as the primary material for non-load-bearing internal partitions in general industrial, residential, and public construction projects.

Projects using lightweight partition boards as non-load-bearing interior walls in general industrial, residential, and public buildings are classified as lightweight partition wall projects.

The third-generation environmentally-friendly and energy-saving partition boards, vigorously promoted by the country, boast advantages such as moisture resistance, earthquake and noise insulation, fireproof and thermal insulation, small land occupation, high strength, and convenient construction.
