Is it safe for knob & tube to be touching insulation facing?
Is it safe for insulation to be placed underneath existing knob and tube if only the insulation paper facing is touching the wires? Or is it be better to remove the insulation and leave a portion of the wall uninsulated? In WA, USA if that matters.
For the sake of argument assume replacing the K&T is not possible.

Answer:
No, knob and tube wiring should not touch anything other than air, knobs and tubes. If you have enough access to add faced insulation, then you have enough access to replace the wiring.
