Thermal bridging visualized
There is also cold air washdown caused by this thermal bypass problem in the image below from the attic that I have since fixed using rigid foam which was spray foamed in place to stop the air and then covered with loose fill cellulose. The fiberglass insulation not being encapsulated is also an issue. I'm going to build out the framing to expand the cavity to about 10.5" thick and use insulweb and dense pack cellulose to get that space air tight and get to almost R40.
