ICC Commercial Building Inspector Practice Test

What is the minimum thickness required for anchored masonry veneer used as a weather covering?

1. 2.5 inches

2. 2.625 inches

3. 3 inches

4. 3.5 inches

The correct answer is: 2.625 inches

The minimum thickness required for anchored masonry veneer used as a weather covering being 2.625 inches is aligned with building codes that ensure the structural integrity and effective performance of the masonry. This thickness is specified to provide adequate strength and durability in resisting environmental forces, taking into account factors like wind uplift and moisture penetration, which are crucial for weather resistance. Additionally, this specific measurement addresses thermal performance, as insufficient thickness might lead to heat loss or condensation issues within wall assemblies. The code requirements help ensure that the veneer complies with both structural and insulating properties, thus safeguarding the building against weather-related damage. Such specifications are vital for maintaining the longevity and performance of masonry veneers in various climates.
