what is faced and unfaced insulation
1 - 1 of 4 Posts
One has a vapor retarder, one doesn't. All the plastic foam boards come either faced or unfaced. Also get denim batts, rock wool, etc. that are better than fiberglass, my least favorite;
Fiberglass batts are 15" and 23", made to stand alone, slightly compressed in the stud cavity, not requiring stapling the paper facing for an effective moisture retarder. All of the faced ones with plastic or paper should not be used below grade in most of the U.S., where are you located? And, welcome to the forum!
