A new building owner inquires about insulation: The floor of the attic in my building is fully insulated. I would like to insulate the ceiling because I plan to store some items there that should have some protection from the heat. I do not plan to cool or heat the space. Can I just have someone tack up some rolled fiberglass insulation between the joists?
Mac answers: I would advise an experienced or licensed insulation contractor when doing this kind of work. You have to take into consideration issues of ventilation. If not done properly moisture can accumulate and result in mold. Also, even with insulation the attic will still be as hot as the hinges of Hell in July and August. You should find out just how much heat those items can handle.
