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, serving as the primary material for non-load-bearing internal partitions in general industrial, residential, and public buildings.

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 environmental-friendly and energy-saving partition boards, vigorously promoted by the country, offer advantages such as moisture resistance, earthquake-proof and noise insulation, fire prevention and thermal insulation, small footprint, high strength, and easy construction.
