Hey Mike, I have a question? I am relatively new to radiant barrier so here it goes. I live in Las Vegas, NV and recently upgraded my attic insulation from an R-4 to an R-51 (my house is approx 32 years old) so would it be beneficial to install radiant barrier on the roof sheeting under the shingles and tar paper ? It would seem that if it goes on the roof then the heat would be prevented (to some degree from getting into the attic to begin with thereby making my insulation just that more effective. any input is appreciated
