NEND | Im building a new house now and just got a quote on urethane foam for my walls. Not sure what weight of foam but 3" will give me R-21. They told me that a vapor barrier would not be required on the wall when using foam. I live in NE North Dakota, very cold, and was wondering what your thought on that would be. I have 2x6 walls and will only putting 3" of foam and leaving a space between the foam and drywall cause a pocket for moisture to accumulate? Any info would be great, Thanks in advance. | |
