Hi Shah: The newer radiant barrier foils are amazing products. See them at www.btubusters.com and www.bestinsulation.com I also found a great site for discount prices on tools. I got a Porter Cable circular saw for $119 and a computer for less than $500. If anyone is interested, click on www.hotwater.bigsmart.com Good luck with the foil, it's great stuff, I'm having my whole roof fitted with it. B.
