A stud system for supporting spray insulation to an exterior surface of a
concrete structure is disclosed. The stud includes a wall abutting
surface, and a laterally extending web for promoting adherence of foam
insulation when applied to either side of the stud. The stud is attached
to the structure by anchoring to one or more form ties protruding from
the structure, or by driving fasteners into the structure. The stud also
includes a second surface which can be used for attachment of exterior
finishes such as vinyl siding or stucco.
