Heat Reflecting Sheets

Does anyone have an opinion on these foil sheets that are attached to the underside of the rafters to reflect the infred heat in attics.  Looking at youtube stuff you see several approaches.  The most sensible one being the foil not touching anything more than necessary.  This would lead you to believe that foil on osb for roof deck or for foil sided insulation to be much less effective.

People seem to finally understand the importance of energy effeciency.
