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), reinforced cement boards with steel wire (wire mesh), 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.

The project using lightweight partition boards as non-load-bearing interior walls in general industrial, residential, and public buildings falls under the category of lightweight partition wall engineering.

The third-generation environmental protection and energy-saving partition boards, vigorously promoted by the country, offer advantages such as moisture resistance, earthquake resistance and noise insulation, fire prevention and thermal insulation, small land occupation, high strength, and easy construction.
