Insulation generally has a paper backing that is stapled to the floor supports.

Maybe the OP could tear out the insulation and use the foam kind meant for walls. I don't know if you can get an R-value as high, but at least you wouldn't have to worry about loose fill ever breaking away.

It is probably safe but I would put on a mask just as a precaution. You don't have to worry about asbestos because they stop using that in the late 70s.

It's not backwards- the paper facing is a vapor barrier, which gets installed toward the warm side, or in this case the upper floor. The insulation gets put in from below, and is usually held in with metal wires that are cut slightly longer than the joist cavities so they're "sprung" into place between the joists to create tension.

I wouldn't worry too much about leaving the fiberglass exposed, unless you've got some huge fans down there that would create enough air movement to cause some of the loose fibers to become airborne. Even then, it's likely a non-issue.

It's a large basement and all the insulation that is in the ceiling is not covered with any material, paper or plastic. It's white, thick, fluffy insualation and we want to know if it's safe that it's uncovered since we use the basement so much and we don't plan on finishing our basement. Also, is it typical that a builder would leave the insulation uncovered in this manner? We would love your opinions and if you think we need to get it covered up.

Thanks for your thoughts.
Suggest you call a local lab that can check it for asbestos. If you don't know who to call, a local licensed general contractor should know. Last time I had this done it cost about seventy five dollars. Another, less effective way would be to determine when asbestos was outlawed in your area and compare it to the time the insulation was installed in your home. Since it could have been installed after the home was built, this would obviously be less effective. It's worth the safety of the home's occupants to clear it through a qualified lab. Good Luck

What did you decide to do?

By the way, Its installed correctly if the paper is facing the conditioned space.

The paper faces the living space iirc.
It would be easy enough to cover it with plastic, stapled to the rafters. Healthier too.

The home was built in 2004, Asbestos was outlawed in 1978!

The situation the OP describes is totally normal. The builder either has to insulate the ceiling or the exterior walls of the basement. Nothing to worry about. If you spend a lot of time down there, finish the basement.
