US Patent 9879416 Composite thermal isolating masonry tie fastener

Cavity walls include fasteners that provide a thermal break. A cavity wall assembly includes a support structure, insulation, and an outer wythe. The insulation is mounted on the support structure. The outer wythe is spaced apart from the insulation, such that a cavity is formed between the insulation and the outer wythe. A tie is attached to the outer wythe. A fastener extends through a portion of the tie, through the insulation, and into the support structure to attach the tie to the support structure. The fastener provides a thermal break between the support structure and the tie. At least a portion of the thermal break is disposed within a width of the insulation.
