Veneer ties must be spaced apart horizontally no more than how many inches?

Veneer ties are a critical component in the construction of masonry walls, particularly in securing the outer veneer layer to the structural backing. Proper spacing of these ties is essential to ensure the stability and integrity of the wall system, especially under various loads and environmental conditions.

The correct spacing for veneer ties is specified at a maximum of 32 inches apart horizontally. This distance ensures that the ties provide adequate support and attachment, preventing issues such as bowing or cracking of the veneer. It also ensures that the wall achieves its structural and thermal performance requirements.

The other options suggest distances that exceed what is allowed, which could lead to insufficient structural support. Proper adherence to these spacing guidelines is vital for maintaining the performance and safety of masonry construction.
