I will post pictures of the install when I get around to it in about a week or so. Will be laying it over the blown in cellulose on the floor and stapling from bottom of rafter up to the ridge. Of course, all of this AFTER I go vacuum out all the cellulose the geniuses blew into the eaves.

FYI...Radiant barrier reflective insulation systems from Innovative Insulation Inc.

I'd like to hear other opinions and I will also be tracking my heating costs versus last year and recalculate usage based on current rates and usage amount. This will be interesting.

And if the RB was able to reduce attic temps, which in turn would keep the decking and shingles cooler, wouldn't I be at least "even" in terms of shingle life if not ahead by a bit?
