This video introduces some of the benefits of furring in 2x6 walls with an additional layer of 1-1/2" foam board insulation. This method has multiple advantages: First, the foam board demonstrably reduces heat loss through thermal bridging. Furthermore, the wall gets more airtight as electrical boxes and wiring can be run on the warm side of the vapor retarder.

Finally, this method results in a marked improvement in the quality of the insulation install, as the insulators no longer have to cut and otherwise fit the fiberglass batts around obstacles like wiring and electrical boxes, which can negatively impact insulation performance.

For those interested in a deeper dive into installing furring, we produced an in-depth video at [ Ссылка ]. We welcome questions and discussion in the comments and you can also reach us at info@cchrc.org.
