What is the minimum thickness requirement for the weather covering of adhered masonry veneer?

The minimum thickness requirement for the weather covering of adhered masonry veneer is crucial for ensuring durability and performance in varying weather conditions. Typically, a thickness of 0.25 inches is specified to provide adequate protection against moisture intrusion, which can lead to significant structural damage if not properly managed.

A thickness of 0.25 inches ensures that the weather covering can effectively resist water penetration while maintaining flexibility and adhesion necessary for the material's longevity. This thickness is typically aligned with industry standards and building codes, emphasizing the importance of adhering to specified dimensions for safety and compliance.

The other choices reflect thicknesses that may not meet the minimum performance criteria established in code, potentially compromising the integrity of the veneer and the building structure over time.
