7. 7 FOUO UNCLASSIFIED Conclusion Steel studs pull heat away from the interior gypsum wall. The heat conducts along the stud and through to the exterior wall of the building. Steel studs pull heat away from the interior gypsum wall. The heat conducts along the stud and through to the exterior wall of the building. EcoStuds are considerably less conductive and minimize the heat that is transferred (lost) to the exterior environment. This results in less energy requirements to maintain a comfortable air temperature within the building.
