First-hand experiences with sprayed-foam insulation?
Am beginning to think that it's a great way of insulating floors over garages, crawlspaces, etc.
Wouldn't consider it for attics, blown-in cellulose seems to be extremely cost-effective as attic insulation.
Walls are a toss-up, to me at least. Though it does seem that spraying the stud cavities is superior (but expensive) when the cavity is open. If I wasn't going to open the wall, then blown-in cellulose would be my choice.
There are plenty of options, my focus is working with older construction that has little or no insulation.

You can get a cellulose that you can blow in the stud cavities and it will stay there for you .
As for as the foam . What I have used can burn or melt like fiberglass so it will let a fire through. The cellulose wont let a fire get through.
You never want to put any kind of insulation up in the floor joist over a crawlspace thats for sure .
