While tearing down ceramic tile and rotted drywall in a bathroom shower repair I noticed that the pink fiberglass insulation had some slight black mold growing on it, so I am opting to replace those columns.
My house was built in the late 1970s and I noted that all of my exterior walls including this bath one had a aprx 2-3 mil thick piece of clear plastic over top of the insulation. This bathroom insulation appears not to be "faced" in that it is pink on both sides (no paper on one side).
I have 2x4 outside wall construction so I purchased R-13 PinkPro or ProPink insulation. Because this is the "good stuff" and is "faced", do I need to put a 2-3 mil thick sheet of clear plastic over top of it?
It is my assumption that because this is "faced" that if I staple the faced part interior so I can see it that is all I should require.
If it matters I will be putting cement board over top of the insulation when I redo the shower stall.
