What barrier should I use under wall shingles to increase insulation in a single wall cabin?
I have a 100 year old redwood cabin in Northern California in the coastal area.
It is single wall construction consisting of 1x12 redwood boards and framing visible on the inside, and with cedar plank covered by redwood shingle on the outside.
I am replacing the shingle and will be repairing damaged cedar plank as necessary.
I do not want to turn the cabin into double wall construction with interior insulation as it will wreck the character.
In addition to building paper, what can I use between the ceder plank and shingles to increase the energy efficiency of the cabin?
Please take into account that this old redwood should not be wrapped in a plastic bag as it needs to breath in this foggy climate.
