Insulation Options for Cabin with No Attic/Vented Space?
I’ve built a camp in south Mississippi, raised 8′ off the ground on piers. I had the help of an old Army buddy who did most of the heavy lifting and who does pole barns for a living; he graciously turned his typical barn design into a ‘cabin’ for me.
I’ve read and read and still don’t have a good idea on how best to insulate. The metal roof is already in place obviously, on top of tar paper and sheathing, so whatever I do has to be done from the inside at this point.
I would prefer not to create an ‘attic’ because that would make the interior ceiling feel pretty low and I’m a bit claustrophobic, but I am not sure how safely I can otherwise best insulate the ceiling space and avoid moisture problems?
Currently the outside temp is 95 degrees and the interior space of the house is 105 degrees. Though I only intend to cool the place when we are there on weekends, it would be nice to insulate and seal well enough to at least run a dehumidifier when we are not there.
What approach should I take? I was thinking R-13 rollout insulation between the 2×6 rafters, and then possibly foam board directly over the rafters and sealing those boards with tape.
Does that sound reasonable?
