Covering exposed insulation paper face

0

Other than gypsum, what else can be put over exposed insulation? Code wont allow for exposed paper. If not tyvek than what specific product can be used? The company that installed my insulation, which failed final inspection won't return calls. I was told nonwoven flame retardant sheet. Anyone have specific product that meets that?

Flame-retardant polyethylene (6 mil, I think) is commonly used. You'd sort of end up with a double vapor barrier, but since they're tight together it's probably not a problem. It's readily available at building materials suppliers.

Regarding your "ridiculous codes" comment, walls of highly-flammable paper are a genuine safety concern. It ignites much more readily than the paper on the face of drywall, for example, and spreads flame very quickly. Surely you prefer that the occupants have a fighting chance at survival, and those downward-trending lines don't happen by accident.
