My house attic is insulated, but I noticed that the attic over the carport is not insulated. The carport is open on two sides. It joins the main house and both attics are open. Does it matter if the carport attic is not insulated? – David
No, it’s not a problem at all. Since the air in the shared attic space is not heated or cooled and is vented to the outside anyway, it doesn’t matter if the area over the carport is insulated. In fact it is better that it’s not in order to lessen the possibility of moisture condensing in that part of your attic.
