"we actually block 97% of energy transfer in and out of the structure",
at the points where radiant heat is the transfer medium.

I think maybe I could keep my ceilings a few degrees cooler in the summer,
if I had a layer of shiny foil over the top of all my attic fiberglass..
Of course, it could shorten the life of my roof shingles by a few months..
