Cracks in an airtight drywall approach
Hello – I installed drywall in my cabin last summer without any poly vapor barrier, following the fundamentals of the airtight drywall approach. Over the winter, fine cracks appeared at some of the drywall seams. This appears to be a common issue with unheated cabins experiencing large swings in temperature & moisture. Now that my air barrier has been compromised I’m not sure what I can do. Repairing the cracks seems futile unless I can provide a heat source during the coldest months.
Thanks for your help,
