insulate over old knob-and-tube wiring?
I'm in a house built in the '20s, which still has a few circuits on the old 2-wire knob & tube wiring, some of which runs across the floor joists in the attic. I really need to add a foot or so of fibreglas insulation to the attic, but am not in a position presently to rewiire the old circuits.
Is there any danger to putting the fibreglas insulation batts over the top of the old wiring?
Thanks for any suggestions or info.
