I recently bought a "fixer upper" lake cabin. It's a 1 1/2 story bungalow from the 1920s. My first large project is going to be gutting the 2nd floor, re-roof, re-insulating, then eventually finishing off the 2nd floor again.
Anyway, the roof is framed with 2x8 rafters. I know I need to circulate air from the soffit vents to the ridge (I'm adding continuous ridge vent in the re-roof), so I was planning on the styrofoam vents under the roof deck. That doesn't leave me much room for insulation - maybe a 6" batt. The house is located in northern WI, so it will see some cold weather. I won't be there much over winter, but I would like to keep the place at 50 degrees when I'm not there and not go broke in the process. Is there anything else I can do to improve the R-value of the attic?
Thanks for the help.
