Partition boards refer to prefabricated wall panels for non-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 lightweight concrete boards (ALC), steel reinforced cement boards, lightweight concrete boards, composite sandwich lightweight boards, and more. Their full name is "Lightweight Strip Boards for Building Partition," serving as the primary material for non-bearing internal partition walls in general industrial, residential, and public buildings.

Projects using lightweight partition boards as non-load-bearing interior walls in general industrial, residential, and public construction projects fall under the category of lightweight partition wall engineering.

The third-generation eco-friendly and energy-saving partition boards, vigorously promoted by the state, boast advantages such as moisture-proof, seismic noise insulation, fire-resistant and thermal insulation, small footprint, high strength, and convenient construction.
