Never cover? Huge fire risk?

(originally posted by Phil Munro) is a report to the Illinois Department of
Commerce and Community Affairs on adding building insulation around existing
K&T wiring. No record of hazard was found in the large number of K&T
installations that had insulation added around them. Also addresses how some
jurisdictions have handled the code aspects.

Thanks for that. It's a good read, and could affect me since I'm in Washington.
