Fiberglass has not been shown to be a carcinogen and is unclassified for this health hazard, but is a dermal and respiratory irritant when disturbed (such as during installation). When used in insulation batts, and not disturbed, it should pose no hazard or irritation.
The vapor barrier or paper backing is properly installed against the first floor of your house. Adding a vapor barrier under the insulation is not a good idea, but you could add a barrier like Tyvek house wrap which allows water vapor to pass, but is an absolute barrier for any particulate and will give you a white smooth surface. If you put the white unprinted side facing the room, it will brighten things and not look too bad. Costs more than plastic sheeting, but is cheaper and easier than hanging drywall.
You need do nothing for health reasons, unless you have ping-pong balls bouncing off it, or some other persistent activity that disturbs the insulation. |
