What is the minimum vertical size (in inches) of the attachment flange of a weep screed placed on a foundation wall before attaching exterior lath?

• A. 2-1/2 inches
• B. 3-1/2 inches
• C. 4-1/2 inches
• D. 5-1/2 inches

Answer: (B)

The minimum vertical size of the attachment flange of a weep screed placed on a foundation wall is crucial for proper drainage and to prevent moisture-related issues in construction. A measurement of 3-1/2 inches ensures that the weep screed is effectively positioned to allow water to drain away from the wall, which helps protect the underlying framework and insulation from potential damage caused by moisture accumulation. This dimension reflects industry standards for building practices that prioritize durability and the longevity of structures. It also aligns with requirements set by organizations such as the International Building Code (IBC) and guidelines from the American Society for Testing and Materials (ASTM), which outline the best practices in moisture management for residential and commercial construction. Other measurements, while they may seem like reasonable alternatives, do not meet the established building codes and could potentially lead to issues such as insufficient drainage or increased risk of water intrusion, making them unsuitable for this application.
