Spray foam hybrid flash and batt help! wet wall cavity
We have new construction and have dry wall up and painted. Have spray foam 2" on exterior wall and flash and batt in wall cavity. Had a cold snap and with humidity in house the vapor went through wall on north and east side of house, hit the spray foam and condensed. We have heat on 62 and have 2 contractor size dehumidifiers running. The humidity level now is 50 , basement is 55. Has been a whole week. How long to dry. It is maine, and rainy out for next 3 days so feel that high humidity outside may help to drive vapor back inside. How long will this take or will we need to remove drywall? Had a professional company do the insulation and it seemed to be 2 " every where. Feeling pretty upset.
