What is the minimum width of materials that should be used to cope parapet walls in relation to the thickness of the wall?

  1. 1

  2. 1.5

  3. 2

  4. 2.5

The correct answer is: 2

The minimum width of materials used to cope parapet walls should be at least twice the thickness of the wall. This requirement ensures that the coping provides adequate protection against water infiltration and weathering, which can compromise the integrity of the parapet and the building structure overall. A wider coping also helps to manage drainage, directing water away from the wall and preventing pooling that could lead to damage over time. Using a width equivalent to two times the thickness promotes durability and stability, making it a standard practice in construction.
