The problem with this theory is that it's never been proven. There's never
been a fire that was proven to be because of K&T wiring that was covered by
insulation. It sounds good on paper and gave the NEC boys something else to
screw people over about, but in all reality, it just doesn't happen.

K&T was designed for free air flow around conductors at all times.
insulation prevents that and can cause overheating and ultimately a
fire since connections are soldered in walls, get solder hot enough
and it will fail
