I am wanting to know the best Insulation to use for keeping the heat out during the summer, and the cold out during the winter. I am looking to be living in places like NV, OR, AZ, ect. Places where it is very hot during the summer, and below freezing during the winter. Someone told me to use R-10. Is that the best? The walls had Styrofoam between the wood and the siding, should I put something in between the wood and the aluminum siding? |
