We went with 5.5" of open cell spray foam insulation on our roof and walls as well as in the basement area. Our interior walls are 2x4s but the main floor exterior walls and roof are 2x6 and the basement area is framed with 2x8s. They sealed around all the windows, doors and any openings for electrical and plumbing pass throughs. We are so glad that we decided to go with the spray foam.
