I'm trying to understand what the difference is between the high dollar stuff that these insulating companies sell and plain aluminum foil, other than the reflectivity might be higher. Right now I'm thinking about just trying an experiment with a few boxes of aluminum foil by stapling it to the rafters with the reflective side toward the roof. Please let me know the fallacies of this if there are any. Thanks in advance. B
