IÃ¢â‚¬â„¢m renovating my bathroom in N.J. The tub is situated against an exterior cinderblock and brick wall. There are vertical ferring strips nailed to the block. My plan was to insert Ã‚¾Ã¢â‚¬ thick white polystyrene insulation between the ferring strips, then tact 6 mil poly vapor barrier, then cement board, then ceramic tile. A contractor who priced the job told me that the new consensus of opinion is to eliminate the vapor barrier because it “trapsÃ¢â‚¬ moisture. Does anyone here agree with this guy? Thanks in advance for any comments.
