in THE MAIN WALL
With snow on the ground today I thought I would take a look at my radiant with the IR camera. My office wall is ICF 2' deep up 4 feet. The block is an honest 2 & 2-1/2" of foam, 6" concrete. Supplying about 100°F to the slab.

    That's very interesting ... I should get a simple IR device.

    Have had properties shot -- My guess is the big delta is the reason. Do you know the R of that foam?

    Have used closed cell on my projects for years and 2.5" at normal temps (70) is amazing when I have had audits done.
