We are building a new house and we are trying to find some good spray foam insulation for about 4000 square foot. We are new to this and not really sure what to look for, meaning what is good and worth paying for or what is crappy and not worth spending are money on.
If yall could send me some advice and/or some good websites to go to that would be great.
Thanks.

Polyicenysyanurate,(spray foam) is the best form of insulation for stick built homes. However, it is about 3 to 4 times the price of fiberglass,(it’ll take about 15 yrs to make your money back on your heating and cooling.)
Wall spray cellulose is best for the money, it’s only about 20 to 30% over the price of fiberglass, but only takes 3 to 4 yrs to get your money back. Also it’s environmentally sound, as it’s 99% recycled material, and the harshest chemical in cellulose is boric acid (which makes a great insect repellent)
Go to greenfiber.com for more info.

Point of interest:
Termites eat styrofoam.
I found this out @ school (2nd year apprenticeship for carpentry).
Where I live the cold kills them so it isn’t an issue but it is something to be considered. That’s why certain parts of the country do not use Insulated Concrete Forms or Structural Insulated Panels.
If you find that you aren’t able to use the foams in your area then I would recommend either the green insulation (made from rockwool) or the white insulation from Johns Manville both of which are Formaldehyde-free (formaldehyde being a known carcinogen).
The green insulation has the higher R-values (as well it provides better sound reduction, fire resistance)
As for the spray foams my wife and I chose Spray Jones to do our basement mainly because the Bio-alternative spray foam was Soy based and I’m allergic to soy.
