Wonderful post Martin. Close to my space, Hilton Head Island, SC, you will find radiant barriers currently being bought for $one.50 sq. ft. put in. This makes no sense when you can have open cell foam mounted for about the same value and obtain the ducts in the envelope and supply a thermal and air barrier simultaneously.

Radiant barriers consist of a remarkably reflective material, normally aluminum foil, which is applied to a person or both sides of numerous substrate elements like kraft paper, plastic movies, cardboard, oriented strand board, and air infiltration barrier materials.
