Parapet Wall Construction

When it comes to parapet wall construction, a lot of things can go wrong. Before erecting parapet walls, it is critical to examine these considerations. Remember that, unlike other outside walls, parapet ( walls have three sides that are visible. Through structural gaps, balloon framing, or electrical and plumbing connections, they become mistakenly connected to the interior space. As a result, it's critical to keep the parapet wall and internal rooms separate. Given below, some useful tips on parapet roof detail.
  1. The parapet wall must be at least 2.5 feet tall above the roof surface. ( The standard parapet height is 3 feet.) In any event, the parapet wall should not exceed 4 feet.)
  2. The parapet wall must have a minimum thickness of 4 inches. (The standard parapet thickness is 9 inches.)
  3. To solve the dampness problem, the parapet wall should be plastered on both sides.
  4. The roof-to-parapet joint should be adequately sealed.
  5. Provide wall-penetration flashing beneath the mortar bed to keep moisture out.
  6. Provide venting to each wall cavity.
  7. Use round "soffit vents" to disperse rain water, especially if the venting holes are in exposed areas.
  8. If there are any venting holes that aren't in use, close them to keep bugs and insects out.
  1. Always build a full brick parapet wall with a minimum height of 3 feet. Do not proceed to the half-brick roof parapet wall (
  2. Always leave room for future overlapping in the column.
