I'm with Wire - it's definitely not a clean... I just installed a new power plug myself behind my TV... though not an outside wall, not that that should be that big of a deal...
Yeah, unless these walls are filled to the edge with spray foam, feeding a few power cables down isn't going to be an issue. With fiberglass you'd just push through the insulation in those specific paths and it still wouldn't be that big of a loss.
Yeah, It's a new building so I hope there is spray foam. But even then it might not be that difficult. Might just need a wire probe.
No one around here does spray foam by default.
It should be. But yeah I don't think it's the default where @wirestyle22 is either.
I wonder what the price difference is? I'm guessing it used to be huge, but perhaps today, not so much??
Now if you were renovating and doing this yourself you can pick up spray foam kits that cost ~$770 which while still pricey, would save money compared to fiberglass.
That's it? We need to replace the insulation in our attic. Might have to do it ourselves if the DIY spray foam is that cheap now.
Yeah, that's per kit, each kit covers ~200 sqf at 1". It wouldn't be unexpected to need 2 or 3 kits to cover a single crawlspace attic.
1" - HAHA, so it's $770 for 57 square feet in reality.
I've also watched it being done (online) - it's an art, like spray painting cars... it takes a good amount of practice to not over spray the amount needed and end up with a ton of waste... in the attic, if it overflows, not that big of deal, but in walls, you don't want to waste a bunch that you're cutting off and discarding.
I purchased a 200ft kit, for like $350 I think, to do my rim joists in my crawl space. It's super easy. I believe once you're spending ~$1000 on materials (depending on local rates) it ends up being cheaper to hire somebody to do for you.
For closed cell foam you can only apply so thick in one pass before it's cured, so to get the R rating you would need for an attic in a colder climate zone, it would be insane to use a closed cell kit. Not only is it stupid expensive to do yourself, but waiting for curing between layers and crawling around in the attic multiple times in a poor mans hazmat suit? No thanks. Typically if you're doing foam in an attic they do a single layer of closed cell, then open cell on top.
When I did my attic I pumped in ~20" (R60) of loose fill fiberglass insulation for like $200... most home improvement stores lend you the machine for free if you buy enough bags, 10 bags in my case. I only used 6 bags and returned the rest with no questions asked. I will definitely go this route again on my next house.
