When it gets really stupid in my head I enjoy new musicians and videos to make peace.

Re: Insulating over knob and tube

I have hung out here for years and have seen the new TOH become a spammer paradise ........ There are a few great posters here to offer suggestions, so be persistent........... I am just a resident retdardant electrician so do not mind my folly.

We behind the the lines just be people.

Here you go.

Safe to do or is this why I pay for insurance?
Also would like to add I have no ridge vents just a peak ventilation system on the roof(forgot what it is called) can I take insulation all the way to roof or not? (edge where roof starts its way up)

Hang in there notchjonsn !!!!
No it is NOT safe to insulate over K & T wiring. Said wiring is air cooled.:(

Re: Insulating over knob and tube

Guess I need an electrician to wire the house before I can attempt to keep the heat in. Any suggestions on someone in ohio area that will do it right. The way other things were done in this house before I took it over I guessing the whole thing will have to be done.

The best thing to do is get 3 or 4 estimates, check their references, the BBB, and Angie's list.

Re: Insulating over knob and tube

thanks for the advice and the laughter one more quick question for anyone who is willing to offer an opinion. Since I cannot add insulation between the main floor ceiling and upstairs floors due to knob and tube, I was wondering about adding/changing insulation against roof rafters. Looking outside while the snow is lightly coming down the outside edges of the roof is melting the snow and you can clearly see from the outside where the joists are there is insulation installed backwards(not by me) against the living portion if you are inside the attic and also along rafters both showing vapor barrier(I said it was a crappy bungalo in Ohio), should I remove rafter insulation or change it to R-19 or better? This should get some of you thinking
