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

Projects involving lightweight partition boards as non-load-bearing interior walls for general industrial, residential, and public buildings fall under the category of lightweight partition wall projects.

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