The recommended minimum thickness for a false ceiling depends on a number of factors, including the type of material used, the structure of the existing ceiling, insulation and soundproofing requirements, and local building codes. Here are some general guidelines:
False ceiling material: False ceilings can be constructed from a variety of materials, such as plaster, metal, wood, PVC, acoustic ceiling panels, etc. Each material has a recommended minimum thickness in terms of thickness. Each material has a recommended minimum thickness, depending on its structural strength and soundproofing properties.
Thermal and acoustic insulation: If the false ceiling is used to improve thermal or acoustic insulation, additional thickness may be required to accommodate insulating materials such as mineral wool, acoustic foam or other insulating materials.
Fixing and structure: The thickness of the false ceiling can also be influenced by the method of fixing and the structure of the existing ceiling. Suspended fastening systems may require a certain thickness to provide a secure and stable installation.
Safety and building standards: Local building standards may specify minimum thickness requirements for false ceilings to ensure structural safety and compliance with building codes
