Veneer tie and wall anchoring systems with in-cavity ceramic and ceramic-based thermal breaks

摘要

Thermally-isolating veneer ties and anchoring systems employing the same are disclosed. A ceramic based thermally-isolating coating is applied to the veneer tie, which is interconnected with a sheetmetal surface-mounted wall anchor. The thermally-isolating ceramic coating is selected from a distinct grouping of materials, that are applied using a specific variety of methods, in one or more layers and cured and cross-linked to provide high-strength adhesion. The ceramic coating maintains a thermal expansion similar to that of the underlying wire formative to prevent cracking. The thermally-coated veneer ties provide an in-cavity thermal break that severs the thermal threads running throughout the cavity wall structure, reducing the U- and K-values of the anchoring system by thermally-isolating the metal components.

主权项

1. A high-strength veneer tie for use with an anchoring system in a wall having an inner wythe and an outer wythe, the outer wythe formed from a plurality of successive courses with a bed joint, having a predetermined height, between each two adjacent courses, the inner wythe and the outer wythe in a spaced apart relationship the one with the other forming a cavity therebetween, the veneer tie comprising:
a wire formative insertion portion for disposition in the bed joint of the outer wythe; two wire formative cavity portions contiguous with the insertion portion; a wire formative attachment portion contiguous with each of the two cavity portions and opposite the insertion portion, the attachment portion being adapted for interengagement with a receptor of a wall anchor; and, a thermally-isolating ceramic coating disposed only on the attachment portion, the coating having low thermal conductivity and transmissivity, the coating being adapted to form a thermal break in the cavity; wherein upon installation within the anchoring system in the cavity wall, the veneer tie restricts thermal transfer between the veneer tie and the wall anchor and between the wall anchor and the veneer tie.
