A wall anchor for use in a cavity wall configured to connect to a veneer tie that joins an inner wythe, and an outer wythe of the cavity wall is disclosed. The wall anchor includes an elongated shaft having a first longitudinal axis, a fastening end section, a receiving end section, and a middle section. The wall anchor system further includes a panel including an interior positioned between at least two end surfaces, and a first insulating member spanning at least a portion of the interior of the panel. The receiving end section of the wall anchor system includes apertures defining an aperture wall for accepting sections of the veneer tie. The wall anchor system further includes a plurality of insulating members covering the aperture wall configured to reduce the transfer of thermal energy by the veneer tie between the inner wythe and the outer wythe.
