Foil Faced vs Paper Vapor Barrier
Is there any real difference in design performance?
I wonder about the vapor barrier effectiveness of paper backed
insulation ? It does seem that foil faced insulation is not readily
available (at HD).
During a recent bathroom gutting and remodelling project, the
contractor removed all foil faced R19 ceiling insulation and the
insulation that was in the exteriaor wall. He replaced with
paper-backed R19 insulation in areas .
