What is the minimum thickness of parapet walls?

6 inches
8 inches
12 inches
125%

The correct answer is: 125%

The correct choice regarding the minimum thickness of parapet walls is 6 inches. Parapet walls are extensions of walls that are located at the roofline and serve various functions, including providing safety from falls and acting as a barrier against wind and water. Building codes and safety regulations often stipulate a minimum thickness to ensure structural stability and durability. To ensure adequate strength and support, the 6-inch thickness is specified as a minimum standard in many building codes. Thicker parapets may be required depending on specific design or structural considerations, such as height and load. Therefore, the stipulated minimum thickness is crucial for maintaining safety and compliance with building regulations, providing necessary support and reducing the risk of failure under various conditions.
