What kind?

Friable Asbestos? Yes.

Non-friable Asbestos? Not so much, but still not great.

Vermiculite? It may or may not contain asbestos.

Fiberglass? Mice love it, and it can make dust, and it only really insulates if it's completely encapsulated by wall, stopping air movement.

Foam? It's combustible, and current thinking is that it should be covered by a 15 minute smoke barrier. (If there's a fire, you have 15 minutes to get out before it produces toxic smoke.) There are expensive paints that can do this, or you can cover it with sheetrock.

How dangerous is vermiculite plus asbestos insulation?

Vermiculite insulation containing asbestos is about as dangerous as any other type of insulation that contains asbestos. If it becomes airborne and people breath in the fibers, their risk of contracting an asbestos related disease increases. The amount of increased risk depends on how much asbestos is in the insulation, how much becomes airborne, how long the people are exposed to the airborne fibers, and whether they smoke tobacco products.


When do you consider a basement unfinished?

To simplify this as much as possible, an unfinished basement is a basement that is lacking the elements that would typically be seen in a finished room. These would include items like flooring, ceilings, insulation, and finished walls. Typical unfinished basements are as such quite bare, usually with the cement of the foundation making up the walls and the flooring, with the inner workings of the ceilings exposed.
