I have read about stucco as the exterior for straw bale houses in a humid climate can raise the moisture level within the straw to a level that might cause rot. So, the question is that assuming you do your best in all aspects of a straw bale house with good roofing and avoid leakage by having extended overhangs, a proper foundation, etc. Now if it's humid and the stucco absorbs moisture, it apparently will wick down to the straw where it will not be able to escape. Moisture levels are supposed to be about 15 to 20% at the most. Higher than that for any period of time, the straw rots and the walls can fail. Am I correct with this deduction? Does anyone live in a strawbale house in a moist or humid climate? In the upper midwest, The summers, spring, fall can be very humid with days of wet with rain that obviously can touch the stucco exterior of a house.
