great stuff

[comfortmaster1]

You know. That "great stuff" that comes in a can at Home Depot. It foams up and takes what ever shapes.

Question: How come they don't use that for insulation? Like pump it into and behind drywall or even attics? I would rather mess with that than fiberglass.

They do, its just more expensive, because wiring "has" to be done in conduit, boxes need to be sealed, and the product is just more expensive...

Money talks. Seen something similar on commercial aps. for sound proofing.

I've seen them use it in high end new construction. Imagine trying to run a new circuit down an exterior wall a few years down the road.

Hence, the need to run wiring in conduit...

Well of course. But I mean a new "after thought" circuit. You could use Romex and still insulate it with this stuff. But later on if you wanted to add a circuit? Wouldn't it be a pita to do??

Why would you have to use conduit? Personally I would prefer it but I've seen Romex used with this stuff.

Thanks for the response.

How much more expensive? Where can I get some? I don't want to buy a bunch of cans.

This is what it is. Do a Google search or check the local box stores for kits. "polyurethane foam insulation"
