Thermal wall anchor
A wall anchor for use in a cavity wall includes an elongate body having a driven end portion and a driving end portion. The driven end portion is adapted to be threadedly mounted on the inner wythe of the cavity wall. The elongate body includes a barrel portion adjacent the driven end portion. A first end of the barrel portion is adapted to abut the inner wythe of the cavity wall when installed. A thermal coating is disposed on the first end of the barrel portion. The thermal coating is configured and arranged to reduce thermal transfer in the cavity wall between the elongate body and the inner wythe when installed.
1. A wall anchor for use in a cavity wall to connect to a veneer tie to join an inner wythe and an outer wythe of the cavity wall, the wall anchor comprising:
an elongate body having a driven end portion and a driving end portion, the driven end portion being adapted to be threadedly mounted on the inner wythe of the cavity wall, the elongate body including a barrel portion adjacent the driven end portion, a first end of the barrel portion being adapted to abut the inner wythe of the cavity wall when installed; and
a thermal coating disposed on the driven end portion and the first end of the barrel portion, the thermal coating being configured and arranged to reduce thermal transfer in the cavity wall between the elongate body and the inner wythe when installed.
2. The wall anchor of claim 1 , wherein the first end of the barrel portion comprises an end surface of the barrel portion, the thermal coating being disposed on the end surface such that the thermal coating is positioned between the end surface and the inner wythe of the cavity when installed.
3. The wall anchor of claim 1 , wherein the driven end portion comprises a threaded portion, the thermal coating being disposed on the threaded portion.
4. The wall anchor of claim 1 , wherein the thermal coating is disposed on the entire elongate body.
5. The wall anchor of claim 1 , wherein the driving end portion includes a drive head having an interior surface defining a receptor for receiving a portion of a veneer tie, the thermal coating being disposed on the interior surface of the receptor such that the thermal coating extends into the receptor to coat the interior surface defining the receptor.
6. The wall anchor of claim 1 , wherein the barrel portion is a first barrel portion, the elongate body further comprising a second barrel portion adjacent the first barrel portion and having a diameter larger than a diameter of the first barrel portion, the thermal coating being disposed on both the first and second barrel portions.
7. The wall anchor of claim 1 , wherein the driving end portion comprises a drive head and the driven end portion comprises a threaded portion.
8. The wall anchor of claim 7 , further comprising an external seal disposed on the elongate body at a junction of the drive head and the barrel portion, the external seal being configured to seal a channel formed by insertion of the wall anchor into a wall, precluding water and vapor penetration therethrough.
9. The wall anchor of claim 7 , further comprising an internal seal disposed on the elongate body at a junction of the threaded portion and the barrel portion, the internal seal being configured to seal a channel formed by insertion of the wall anchor into a wall, precluding water and vapor penetration therethrough.
10. The wall anchor of claim 1 , wherein the thermal coating is selected from the group consisting of thermoplastics, thermosets, natural fibers, rubber, resins, asphalts, ethylene propylene diene monomers, acrylics, nylons, epoxies, silicones, polyesters, polyvinyl chlorides, polyethylenes, chlorosulfonated polyethylenes, lanthanum, cerium, praseodymium, neodymium, promethium, samarium, europium, gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium, lutetium, indium, scandium, yttrium, zirconium, hafnium, titanium, silica, zirconia, magnesium zirconate, yttria-stabilized zirconia, and derivatives and admixtures thereof.
11. The wall anchor of claim 1 , wherein the thermal coating has a thickness of at least 3 microns.
12. A wall anchor for use in a cavity wall to connect to a veneer tie to join an inner wythe and an outer wythe of the cavity wall, the wall anchor comprising:
an elongate body having a driven end portion and a driving end portion, the driven end portion being adapted to be threadedly mounted on the inner wythe of the cavity wall, the elongate body including a barrel portion adjacent the driven end portion, a first end of the barrel portion being adapted to abut the inner wythe of the cavity wall when installed; and
a thermal coating disposed on the first end of the barrel portion, the thermal coating being configured and arranged to reduce thermal transfer in the cavity wall between the elongate body and the inner wythe when installed.
13. The wall anchor of claim 12 , wherein the first end of the barrel portion comprises an end surface, the thermal coating being disposed on the end surface such that the thermal coating is positioned between the end surface and the inner wythe of the cavity when installed.
14. The wall anchor of claim 12 , wherein the driven end portion comprises a threaded portion, the threaded portion being free from thermal coating.
15. The wall anchor of claim 12 , wherein the thermal coating is disposed on the entire elongate body.
16. The wall anchor of claim 12 , wherein the driving end portion includes a drive head having an interior surface defining a receptor for receiving a portion of a veneer tie, the thermal coating being disposed on the interior surface of the receptor such that the thermal coating extends into the receptor to coat the interior surface defining the receptor.
17. The wall anchor of claim 12 , wherein the barrel portion is a first barrel portion, the elongate body further comprising a second barrel portion adjacent the first barrel portion and having a diameter larger than a diameter of the first barrel portion, the thermal coating being disposed on both the first and second barrel portions.
18. The wall anchor of claim 12 , wherein the driving end portion comprises a drive head and the driven end portion comprises a threaded portion, the wall anchor further comprising:
an external seal disposed on the elongate body at a junction of the drive head and the barrel portion, the external seal being configured to seal a channel formed by insertion of the wall anchor into a wall, precluding water and vapor penetration therethrough; and
an internal seal disposed on the elongate body at a junction of the threaded portion and the barrel portion, the internal seal being configured to seal a channel formed by insertion of the wall anchor into a wall, precluding water and vapor penetration therethrough.
19. The wall anchor of claim 12 , wherein the thermal coating is selected from the group consisting of thermoplastics, thermosets, natural fibers, rubber, resins, asphalts, ethylene propylene diene monomers, acrylics, nylons, epoxies, silicones, polyesters, polyvinyl chlorides, polyethylenes, chlorosulfonated polyethylenes, lanthanum, cerium, praseodymium, neodymium, promethium, samarium, europium, gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium, lutetium, indium, scandium, yttrium, zirconium, hafnium, titanium, silica, zirconia, magnesium zirconate, yttria-stabilized zirconia, and derivatives and admixtures thereof.
