Do not bury the question

Adding insulation over unknown old wiring can make future access more difficult and may conflict with weatherization requirements when the wiring is active.

Rhode Island weatherization guidance is specific

The Rhode Island Weatherization Field Guide says testing for active knob-and-tube must be done by a licensed Rhode Island electrician and does not allow attic insulation over active knob-and-tube under the state WAP guidance.

Coordinate the sequence

Electrical evaluation and any needed decommissioning or replacement should be planned before insulation work closes off access.
