I know this is off topic and if there is a better forum to do this in, please let me know. I was wondering if reflective insulation works or is this some sort of gimmic. I live in Maryland as for climate. I am getting an addition put on and i was going to put this against the stud work and then insulate with fiberglass batts too. I have read the philosophy behind it and it makes sense, but that doesn't always correlate to reality.
