Some real life data

It isn't hot today, but it is clear. So I took a few readings of the outside and inside of the west wall, it is late afternoon, 4pm. It does look as though the radiant barrier (which I might double to add a bit of R-value) is going to do a nice job keeping the heat out.

Another improvement, will also be a coating of Henery's Envirowhite roof coating, which will added to the R-19 that will be on the ceiling, with luck this summer will be comfortable.
