Which side of the barrier faces down and into the attic?	Guest User 4/3/2007	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/9393/find/
The aluminum side needs to face an airspace. it actually doesn't make any difference which direction. Beware though that with conventional shingles a radiant barrier can "bake" the shingles.

Would radiant barrier be a waste of money if I am putting on a white metal roof? Again it needs to be facing towards the inside where air is?	Guest User 2/9/2009	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/9395/find/
Donna, We have used a lot of radiant barrier on shingle roofs. The people we have installed it for claim they see a energy cost reduction, but I am very skeptical. It is not anything we try to sell, the home owners usually have seen it advertised or a demo of it somewhere. We have never installed it under a metal roof. Personally, I want to lower my energy costs as much as possible. We are about to install a 24 gauge standing seam on my house--I will not be using a radiant barrier under my roof. The foil side goes down. [email protected]	Guest User 2/10/2009	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/9396/find/
