Minimum thickness of 50 mm

A Non-combustible materials are a requirement for a fire-rated floor-ceiling assembly in a residential building in order to prevent the spread of fire between floors.

C: The assembly must be labeled with a fire rating to ensure that it has been properly tested and meets safety standards.

D: The assembly must be continuous from wall to wall in order to prevent fire from spreading through gaps or openings.

B: While it may seem like a thicker floor-ceiling assembly would provide better fire protection, the specific thickness requirement is determined by building codes and standards and may vary depending on the type of construction. Therefore, a minimum thickness of 50 mm is not a universal requirement for all fire-rated floor-ceiling assemblies in residential buildings.
