Abstract

A structural panel for a building structure includes first and second stud members each including a neck. Openings and venturi bridges are formed in the neck. At least one flange is attached to the neck. A foam panel extends between the studs. The openings in the neck limit the heat transferred from the stud to the edge of the foam panel. The venturi bridges in the neck also limit the transfer of heat from the neck to the edge of the foam panel.
