I have a house built in 1941 - small ranch with full attic and basement.
Insulation in attic is old with newspaper dated 1950 and probably old wool insulation on top. This insulation is between the floor Joists (?) and does not come up to the top of them. It is very dusty and just removing a small sends clouds of black dust into the room. I am very concerned about getting this dust into the rest of my house and would prefer to leave it putting a layer of insulation over it or using that pink styrofoam insulation and just resting that on top/across of the floor joists. The middle of the attic has a floor which I am not about to remove and old insulation under that as well but I'd at least like to add insulation to the open areas.
Is there any horrible reason why I cannot just ad insulation ontop of the old as long as we stay below the floor level or top of joists?
