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 driving end portion includes a drive head including an interior surface defining a receptor for receiving a portion of a veneer tie. A thermal coating is disposed on the interior surface defining the receptor. The thermal coating is configured and arranged to reduce thermal transfer in the cavity wall between the elongate body and a veneer tie when attached to the elongate body.
