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. The full name is Lightweight Strip Boards for Building Partition, serving as the main material for non-load-bearing internal partitions in general industrial, residential, and public construction projects.

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

The third-generation environmentally-friendly and energy-saving partition boards, vigorously promoted by the country, offer advantages such as moisture-proof, earthquake-resistant and sound-insulating, fire-retardant and heat-insulating, space-saving, high strength, and easy construction.
