Conclusion

• Steel studs pull heat away from the exterior
  concrete wall. The heat conducts along the stud
  and through to the interior wall of the building.
• Eco-Z studs are considerably less conductive and
  minimize the heat that is transferred from the
  exterior environment into the building. This
  results in less energy requirements to maintain a
  comfortable air temperature within the building.
