Radiant barrier on the attic floor, on top of the insulation?
I received the question below from a friend of mine living in the Central valley of California. Living and working in the Pacific Northwest I don’t have any real world experience with radiant barriers. Any thoughts…?
What is your opinion regarding radiant barriers in residential attics? We have a quote from a contractor for 80 cents/sq ft. – which is approximately $2,500 for our house. His system involves laying rolls of the radiant barrier directly on top of the attic insulation. We have a whole house fan, so would a radiant barrier provide significant additional savings? Your thoughts?
