When installing HOUSE wrap, how far should edges and ends be lapped?

• A. 1 inch on edges and 3 inches on ends
• B. 2 inches on edges and 6 inches on ends
• C. 3 inches on edges and 4 inches on ends
• D. 4 inches on edges and 8 inches on ends

Answer: (B)

The recommended lapping distance for house wrap is crucial for ensuring a weather-tight installation. Lapping helps to prevent water intrusion by directing moisture away from the structure. The choice stating 2 inches on edges and 6 inches on ends is effective because it provides a sufficient overlap to ensure that rainwater runs off the wrap rather than seeping underneath it. The 6-inch lap on the ends is particularly important as it ensures more robust water protection at the points where larger amounts of water may accumulate, such as at seams or transitions between different sections of wrap. The 2-inch overlap on the edges provides enough coverage to maintain the integrity of the wrap, while still being manageable for installation. Using these measurements helps to align with industry best practices for house wrap installation, which focus on maximizing moisture resistance without complicating the installation process. These specifications contribute to a more durable building envelope, enhancing the long-term performance of the structure against the elements.
