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

Labeled with a fire rating
Non-combustible framing
Minimum thickness of 6 mm
Continuous from floor to underside of roof sheathing

The correct answer is: Minimum thickness of 6 mm

In order for a fire-rated glazing assembly to meet building codes, it must be labeled with a fire rating, have non-combustible framing, and be continuous from floor to underside of roof sheathing. This means that it must have a specific fire-resistance rating and be able to withstand high temperatures for a certain period of time. However, the minimum thickness of 6 mm is not a specific requirement for fire-rated glazing assemblies. It may vary depending on the type of glazing material and the desired fire resistance rating. Therefore, option C is not a requirement for a fire-rated glazing assembly in a commercial building.
