Exterior metal veneer must be attached with fastenings or ties spaced no more than what distance?

0.005 inches
0.014 inches
0.0149 inches
0.02 inches

The correct answer is: 0.0149 inches

The requirement for the spacing of fastenings or ties for exterior metal veneer is crucial to ensure structural integrity and proper support of the veneer. The correct answer indicates that fastenings or ties must be spaced no more than 0.0149 inches apart. This spacing is designed to provide adequate support and help prevent issues such as separation, warping, or failure of the veneer system. The precise measurement of 0.0149 inches likely comes from industry standards or building codes that dictate performance and safety criteria for exterior applications. Ensuring that the fastenings are spaced this close together allows for the distribution of weight and stresses evenly across the surface, thereby enhancing durability and maintaining aesthetic appeal. Understanding this requirement is essential for anyone involved in construction or renovation projects that include exterior metal veneers, as proper installation directly affects the longevity and effectiveness of the building envelope.
