My friend needs me to help him install fiber cement siding on his cabin in the woods. The porcupines are eating the exterior wood. He built this back in the 80s when he was young and techniques were a little different than today. He put t-111 siding over the studs with batt insulation paper faced toward the interior. HOWEVER, he stapled plastic over the studs before he installed cedar planks on the interior.
So now we are not sure if we should make a rain screen wall on the exterior when we install the fiber cement due to the possible issue of moisture being trapped between siding and tar paper if we go that route. I have read many articles in Building Science and have used those principles as often as i could but am very unsure about this one? This cabin has a wood burning stove inside and is used as a get away cabin in northern PA so there are months that no windows get opened.
Any advise will be greatly appreciated so we do not mess this place up!
