Radiant barrier foil

[opiesche]

A few months ago, I finally took the step to install some radiant barrier in my attic. Here in NorCal, summers go well above 95 degrees outside for a period of 2 months or so, with the sun beating down all day long, and the house gets incredibly hot - especially the second floor, of course (there's no AC). After stapling radiant barrier to the inside of the trusses only on the south facing side of the roof, max interior temperature on hot days is down as much as 8 degrees. The roll cost 100 bucks. If I had central AC, the barrier would probably have paid for itself in the first summer. As it stands, temperatures are much more comfortable with it. Anyone having heat problems, I can highly recommend this stuff!
