Which of the following is not a requirement for a fire-rated glazing assembly in a residential building?

  1. Labeled with a fire rating

  2. Non-combustible framing

  3. Minimum thickness of 6 mm

  4. Continuous from floor to underside of roof sheathing

The correct answer is: Minimum thickness of 6 mm

Fire-rated glazing assemblies in residential buildings must meet certain requirements to ensure their effectiveness in preventing the spread of fire. Option C, a minimum thickness of 6 mm, is not one of these requirements. The other options, labeled with a fire rating, non-combustible framing, and being continuous from floor to underside of roof sheathing, are important factors in determining the effectiveness of a fire-rated glazing assembly.
