bobp:

How specific are they? Blown-in, fiber glass batts, foam board, etc.?

I can see where rigid foam board would present a problem, in that one would have to cut into it. Blown-in would be a matter of pushing the stuff aside. Batts would have to be cut as well.

I guess he electricians will have to have a working relationship with the insulation people. That is, after you finish dealing with the sheet rock installers and the painters, etc.

SHOULD a junction box be covered with insulation, anyhow? Is heat a factor?
