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." These include glass fiber reinforced cement boards (GRC), glass fiber reinforced gypsum hollow boards (GRG), aerated concrete boards (ALC), steel wire 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 primary material for non-load-bearing internal partitions in general industrial, residential, and public construction projects.

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

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