Foam Insulation Cost

Anyone have it in their home? Can you tell a difference in house temp, energy costs, etc. How much would installation be on an existing 2,100 sq ft. house. Anyone with any experience with something like this please comment.

Sorry, read too quick.
So only the attic?

would only be able to do the Attic on an existing and even then only the ceiling, not the rafters unless you are going to change the roof. Somebody correct me if I am wrong, but this is how it was 5 years ago when I built.

I think stout has a pretty good bit of experience with that type of insulation...just keep this on the first page and he will eventually check in...

Me and a buddy blew cellulose insulation into his house in about 2 hrs and less than $300 bucks...contractor wanted $2k

Glad to see this topic, actually. This past weekend my folks had a radiant barrier sprayed in their attic and got additional foam insulation sprayed in as well...with a promise from the AC repair company that their electricity bill would be reduced by 25% on average.
Did they get hosed, or is this "energy efficient" home concept really the new thing I just need to understand better?

I recently built a house and did the exterior walls and the attic, and it has been a huge difference from our former house that was just the normal batten insulation. I'm not sure how much difference doing the attic only would be, but I would think it could only help.

My house is an ice chest. 6" foam on roof, walls are Structural Insulated Panels (SIPs). Ventilation is system required to bring in fresh air.
Amazing how cool it stays inside during the summer. My previous house was like a damn oven when you got home from work.

I've heard good things about foam. I know a handful of people who have done it and they all seemed to be very happy with it. This was within 6 months of them getting it done, so I don't know the long term satisfaction. As someone mentioned, has to be aware of trapped humidity but I think if done the right way or the right type, not a major issue.
One of the guys who had foam done to and existing home had a study done on his home where they see where you are losing A/C-Heating through gaps through out the house and how much heat comes in from the windows and stuff like that. He said it was eye opening, I'd love to do that but I'm afraid of what I will find or already know.

If you have cellulose or blown in fiberglass already, I would just look into adding a few more inches to it as it settles over time and then I would add radiant barrier to the rafters and the backside of the decking.
Foam is really most beneficial when you can do the whole house in it and form an "envelope" IMO.
The radiant barrier will keep heat out of your attic so the A/C doesn't work as hard and you don't have a pocket of hot air sitting on top of your house. The added cellulose or fiber will just increase your R-value which is always a good thing.
If you have batting then still do all of the above. Add cellulose on top of the batting.
