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, composite sandwich lightweight boards, and more. The full name is Lightweight Strip Boards for Building Partition, serving as the primary material for non-load-bearing interior 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 eco-friendly and energy-saving partition boards, vigorously promoted by the country, boast advantages such as moisture resistance, seismic sound insulation, fire prevention and thermal insulation, small footprint, high strength, and easy construction.
