Blown in insulation roughing tips

That doesn't sound like wiring. That sounds more like a booby-trap.

Yeah, it pretty much was. You had to watch where you put your hands as you were climbing into the attic. :roll:

I always used the hot BB method where I heated a ball bearing at the top of the wall and dropped it down where it melted its way down to the bottom. This works well until you heat the BB too much and it sets the wall on fire. You had better have some water available when this happens and extra BB s because when you pour water on one melting its way down it will stop where the water hits it. If you think I am kidding just wait until you have to wire one of these nightmares.

Dont leave us hanging,
What size bearing?
How did you heat it.
how far will it travel?

So if the insulation heats when it dries and can damage insulation of conductors or even make smurf tube warp..why not use metal flex and metal boxes then your nightmare is only slight challange..Yet at modern day prices I am amazed that people can even afford to remodel..

Would it not make sense to just wire the house in metal flex? then add the wires after they blow in the insulation..

I have wired these nightmares and I think you must be kidding. Hot bearings dropped into the wall cavity?? That is FUNNY!! I can only imagine the ensuing chaos, possibly hidden/existing wires being shorted, and that wonderfull burning smell...

Then actually pour water into the wall cavity to stop it???
Ummm... OK.

Or another possible result:

Homeowner makes call to plumber saying they smell sewer gas...

Plumber finally opens wall up after pressure testing to find a romex cable running right thru a PVC vent line.

oooomigosh...
