I am in the process of insulating my attic and was wondering which type of sprayed foam insulation is better to use. The home is in metro Atlanta, GA. The winters can and do get pretty cold (below freezing); the summers are very hot (currently 96 degrees F).
I've read various articles from websites that seem to have a bias of one or the other. Closed cell seems to be the most popular, yet more expensive product.
However, I would like to hear from some fellow Polkies about which way to go.
I am going to have the underside of the roof sprayed. The shingles are seal tab shingles on the roof.
Any advice would be greatly appreciated.
P.S.: If any Polkies provide these services, let me know.
