Thermally-isolating wall anchors and reinforcement devices and anchoring systems employing the same are disclosed for use in masonry cavity walls. A thermally-isolating coating is applied to the wall anchor, which is interconnected with a wire formative veneer tie. The thermally-isolating 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 thermally-coated wall anchors 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.

1. A wall anchor for use in a cavity wall having an outer wythe and an inner wythe in a spaced apart relationship and forming a cavity therebetween, the wall anchor comprising: one or more leg portions configured to extend into the cavity and formed from wire formative;a veneer tie receptor portion
1. A wall anchor for use in a cavity wall having an outer wythe and an inner wythe in a spaced apart relationship and forming a cavity therebetween, the wall anchor comprising: one or more leg portions configured to extend into the cavity and formed from wire formative;a veneer tie receptor portion contiguous with the one or more leg portions, the veneer tie receptor portion formed from wire formative and configured to engage a veneer tie mounted in the outer wythe; anda thermally-isolating coating disposed on the veneer tie receptor portion and retained with the veneer tie receptor portion prior to installation of the wall anchor in the cavity wall, the coating being selected to have low thermal conductivity and transmissivity, the coating forming a thermal break in the cavity;wherein upon installation in the cavity wall, the wall anchor restricts thermal transfer between the veneer tie and the wall anchor and between the wall anchor and the veneer tie. 2. The wall anchor of claim 1, wherein the veneer tie receptor portion and the one or more leg portions are made from mill galvanized, hot galvanized, or stainless steel. 3. The wall anchor of claim 2, wherein the one or more leg portions is free from thermal coating. 4. The wall anchor of claim 2, wherein the thermally-isolating coating is disposed on only the veneer tie receptor portion. 5. The wall anchor of claim 2, wherein the thermally-isolating coating is disposed on the one or more leg portions. 6. The wall anchor of claim 2, wherein the veneer tie receptor portion comprises an eyelet defined by an interior surface of the receptor portion, the thermally-isolating coating being disposed on the interior surface defining the eyelet. 7. The wall anchor of claim 6, wherein at least parts of the interior surface of the receptor portion are in opposed relation with each other. 8. The wall anchor of claim 6, wherein the wall anchor comprises two leg portions extending into the cavity and the veneer tie receptor portion eyelet interconnects the two leg portions. 9. The wall anchor of claim 1, wherein the one or more leg portions is free from thermal coating. 10. The wall anchor of claim 1, wherein the thermally-isolating coating is disposed on only the veneer tie receptor portion. 11. The wall anchor of claim 1, wherein the thermally-isolating coating is disposed on the one or more leg portions. 12. The wall anchor of claim 1, wherein said one or more leg portions comprises two leg portions extending into the cavity and a rear leg extending between the two leg portions. 13. The wall anchor of claim 12, wherein the thermally-isolating coating is further applied to the leg portions and the rear leg. 14. The wall anchor of claim 1, wherein the veneer tie receptor portion comprises an eyelet defined by an interior surface of the receptor portion, the thermally-isolating coating being disposed on the interior surface defining the eyelet. 15. The wall anchor of claim 14, wherein the wall anchor comprises two leg portions extending into the cavity and the veneer tie receptor portion eyelet interconnects the two leg portions. 16. The wall anchor of claim 1, wherein the thermally-isolating coating is one or more layers of a compound selected from the group consisting of thermoplastics, thermosets, natural fibers, rubbers, resins, asphalts, ethylene propylene diene monomers, and admixtures thereof. 17. The wall anchor of claim 16, wherein the selected compound is an isotropic polymer selected from the group consisting of acrylics, nylons, epoxies, silicones, polyesters, polyvinyl chlorides, and chlorosulfonated polyethylenes. 18. The wall anchor of claim 16, wherein the thermally-isolating coating includes a prime coat; and wherein outer layers of the thermally-isolating coating are cross-linked to the prime coat to provide high-strength adhesion to the wall anchor cavity portion. 19. The wall anchor of claim 16, wherein the thermally-isolating coating reduces the K-value of the wall anchor to a level not to exceed 1.0 W/m2K. 20. The wall anchor of claim 16, wherein the thermally-isolating coating reduces the U-value of the wall anchor to a level not to exceed 0.35 W/m2K.
