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 lightweight concrete boards (ALC), steel-reinforced cement boards, lightweight concrete boards, and composite sandwich lightweight boards, etc. Their full name is Lightweight Strip Boards for Building Partition, and they are the main materials for non-load-bearing internal partitions in general industrial, residential, and public buildings.

Projects using lightweight partition boards as non-load-bearing interior walls in general industrial, residential, and public buildings 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, earthquake-resistant and sound-insulating, fire-retardant and thermal insulation, small land occupation, high strength, and easy construction.
