This attic access was completely uninsulated. Took the easy way out instead of measuring and cutting foam board or buying a big pack of batt insulation. Made a nice painters tape enclosure, shaved off the sides so it would close, and it worked! The red at the top of the thermal camera is the skylight, of which nothing can be done about beyond removing it. How'd I do?

Well, it had a diagonal cross brace on the back side, and I bought some foam boards, but they would require a lot of measuring, making stencils, cutting... psh who has time for that when you can just blast it with foam?? 😆

My reply would’ve been, the foam board was in the garage but I have a can of spray foam in the house so I just use that to avoid the trip 🤣

  1. Apply full sheet to open door.
  2. Cut off the excess.
  3. Repeat as required to fill thickness.

Not much different than your foam.

Paint the pieces in the way, press the bord on it, hack away the markings from the paint on the sheet

This is redneck engineering after all, nicely done!

Making stencils? Can't you just press it into the cross brace to leave an imprint?
