Knob and Tube wiring

[vintagejoe]

Any reason Knob and Tube wiring can't be covered with blown in insulation?

Not that I know of and I gutted many a houses that had knob and tube with blown cellulose. Really, a lot of those old homes that have been blown have knob and tube.

Thermal insulation problems This a COPY & PASTE

Faced with drafty houses and high heating bills, homeowners often add thermal insulation to their attics and walls. Insulation on top of knob and tube wiring is a major fire hazard.

Remember the first good point of knob and tube wiring? The wire suspended in open air allows heat to dissipate. Loose and rolled insulation counteracts the original open air installation of knob and tube wiring.

In 1987, the National Electric Code prohibited the placement of insulation in contact with this type wiring.

Fix the wiring now, while you can still can get to it.

It will save you a lot of labor over run in the future. $$$$$

I don't do electrical work, but I spend a lot of time in peoples attics in my work.

If it has blown in isolation, It's three times the labor rate.
