- Then goes on to discuss that steel has a much higher conductivity, which may be why it has not had much success in the thermally conscience residential market. On the other hand steel stud construction has been sucessful in the commercial industry, which has less stringent thermal performance requirements.<br /> | - Then goes on to discuss that steel has a much higher conductivity, which may be why it has not had much success in the thermally conscience residential market.

- Mentions that the framing factor can be taken as a measure of the thermal bridging in a walls.<br /> | - Mentions that the framing factor can be taken as a measure of the thermal bridging in a walls.<br /> | ||
- | - states that methods of improving the thermal performance include: reducing the the stud contact area (Raised corners and dimples in the flange), the use of furring strips between walls and exterior sheathing, and reducing the web area or replacing the web with a less conductive material. | ||
- Performed a comparison of using HEATING 7.3, which only looks at thermal bridging through studs. Surface temperatures were 70 °F interior and 20 °F exterior. <br /> | - Performed a comparison of using HEATING 7.3, which only looks at thermal bridging through studs.
