"This is not thermal bridging and it has nothing to do with the blower door.  This is the ceiling plane meeting the wall plane, and this is thin insulation combined with possibley a slight breeze blowing or convection causing cold air to ride up…"

"Matthew, this is not thermal bridging or else it would look like the wall studs and the window header. This is a result of running the blower door in a tight house where air coming in at the soffitt vents is pulled into the building through…"

"Master shows! John, Thanks for the review in Home Energy 101.  Sometimes, as auditors, we get so enamored with the technology, we forget the basics.  Comments like this, keep my feet firmly on the ground, and improved my audit…"
