Discovered that the attic access hatch isn’t insulated, which honestly isn’t surprising given when it was built. No ladder system. I’m working on cutting up some foam boards to glue to the backside. Hopefully it will reduce how much is radiated through this barrier.
Thank you very much. Yes, I’m definitively interested, and saw they come in two variants. I’m on Android for years, but still pondering if a standalone IR cam would not be more universally useful. Probably rather going in that direction, and send it back if the quality and usability is not satisfactory.
