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), high-pressure aerated concrete boards (ALC), steel wire 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 main 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 fall under the category of lightweight partition wall projects.

The third-generation environmentally friendly and energy-saving partition board, vigorously promoted by the state, boasts advantages such as moisture resistance, seismic sound insulation, fire prevention and heat preservation, small footprint, high strength, and easy construction.
