Like spray?

ETA

There is some people who don't like it. Main rub is it doesn't allow the house to breath.

I would not put it in the walls of a house. I would, and will, definitely spray the barn with it it when I finish it. Do a slab or foundation of sorts if you can for a house, if you have to do it on supports, then definitely spray the bottom.

Yeah I’ve heard that too but there is another camp that says houses don’t need to breathe. Even with regular fiberglass insulation, houses these days are tight compared to 50 years ago.
I built my house in 2015 and went with spray in from concrete to roof tip. No issues and my heating/ cooling system has no problems. Even went half ton less on the outdoor unit. More and more people are going with the spray in.
I like it because when i go in the attic it is cool and I can see all my wires and plumbing without having to dig around in insulation.
