I have existing (probably R13) fiberglass batts in my attic and would like to add to it. Problem is a lot of it has been disturbed over the years. The other problem is my air handler is up there and there are ducts running all over the floor. Is additional R19-or-so unfaced fiberglass the way to go? Or, is blown-in cellulose on top of the fiberglass best?
Thanks.
