What is Thermal Bridging?
If you drive by your typical subdivision on a cold morning you can see where every stud is in the house because there is no frost there. That is Thermal bridging; when the heat escapes out of your house or cold is allowed to enter. A book by JOSEPH LSTIBUREK titled Builders Guide to Cold Climates is a great reference for thermal bridging, conditioned crawl spaces, r-value and much more resourceful information.
