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 reinforced cement boards, lightweight concrete boards, and composite sandwich lightweight boards, among others. Their full name is "Lightweight Strip Boards for Building Partition," and they serve as the primary material for non-load-bearing internal partition walls in general industrial, residential, and public construction projects.

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

The third-generation eco-friendly energy-saving partition boards vigorously promoted by the state offer advantages such as moisture resistance, earthquake resistance and sound insulation, fire prevention and thermal insulation, minimal land use, high strength, and convenient construction.
