I’m doing the first part of the thermal certification and I am brand new to this. Being able to see the studs in these walls, they are all exterior facing walls, does that mean these walls are missing insulation?
I could not see the studs on the interior walls.
Taken middle of the day (1pm) and outside temp is 72. The inside temp ranged from 72 (upstairs) to 68 (basement).
The walls appear to be insulated based on your pics. The yellow spot Brian pointed out is where a piece of insulation is missing in the ceiling/attic. It’s normal to be able to see studs in most cases.
You should try to get a better temperature differential by running the AC inside before you scan.
Keep going through the coursework and things will make more sense.
Here is an example of missing insulation in an exterior wall and ceiling. Outdoor temp was about 38 ℉ and Indoor was at 75 ℉ Settings on camera were on auto img20210510_201711.bmp (225.6 KB) img20210510_201732.bmp (225.6 KB)
There’s a lot of good information you’re getting from the folks posting on this forum. Here’s an example of improperly installed insulation from an inspection Monday. There’s a about a 2.5°F difference between the improperly installed insulation and the nearby ceiling 2 feet away.
