What type of ties are impacted by the delamination of core materials in sheathing?

The correct choice regarding the type of ties impacted by the delamination of core materials in sheathing is metal ties for brick veneer. This phenomenon of delamination typically occurs when the structural integrity of sheathing materials is compromised, often due to moisture or poor adhesion.

In the context of brick veneer construction, metal ties play a critical role by connecting the brick to the underlying structural system, usually the studs or sheathing. If the core materials of the sheathing delaminate, it can loosen the metal ties, affecting their ability to properly anchor the veneer. This can lead to structural issues, such as potential detachment of the brick veneer or failure to withstand lateral loads.

Other types of ties, such as aluminum or wood ties, may serve different functions or applications and are not specifically designed to connect brick veneer. Brick ties would be more specifically categorized as a part of the broader category of metal ties for brick veneer connections, but in terms of the impact of delamination on sheathing materials, it is the metal ties that are most directly affected, as they rely on the strength and rigidity of the sheathing for proper performance.
