who knows about spray foam?

[cajunforeman]

I did a ton of research on foam when I was building my house. I couldn't justify the cost vs return by putting in foam. Your a/c will cost more and of course to spray it will cost more. It was going to take at least 20 years to get my money back even including the savings i estimated on my electricity bill being reduced. I also worried about the moisture concerns mentioned above. We don't exactly live in a dry area. I went with blown fiberglass. I figured it was the best bang for your buck. Hope this helps

it is a tough choice and one im still on the fence about.

for my 900 sq ft house it would cost an average of $1000-$1200 for spray foam in just the walls vs I could buy the regular bat r-13 insulation for only $280 plus tax and install it myself. I just keep hearing people saying how great foam is and that you shouldn't consider using anything else but isn't it always like that with the latest greatest new stuff? plus its like 4 times the price of regular insulation and as you say, how long will it take to pay for itself?

i know i will need spray foam in the breaker panel cavity where there is no room for anything other then spray foam with all the wires and small gaps in there, since only the foam can fill and form itself around all of that, but the rest i am still pondering and until your post, i had no gauge on how much foam would save to offset the costs of doing it. i thought the return on investment was more in the range of only 8-10 years.
