Condensate moisture around window frames
I am in the process of foaming and taping the spaces between my interior window frames and boxes. I have noticed that after sealing the gap with tape (after foam has cured) that I begin to have slight moisture on the tape surface only on the bottom section of the window frame. I didn’t notice it after I foamed and before I taped; only after taping. I have also noticed it under my exterior door, on the interior side, despite proper sealing of the door frame on the sill (It’s certainly not water from the exterior making its way in). Important to note that my new house is very tight, and the weather has gotten cold and damp (30F and snowing). My air exchange unit is not working yet and the Sheetrock is being mudded with a bit of heat from electric heaters. Probably a high humidity problem (No humidity numbers to report)? If it’s not, how do I eliminate the condensation that will eventually be covered up by window trim and on the bottom of the exterior door? I plan on holding off on finishing the window boxes with wood trim for the winter to see how it goes and will start running a dehumidifier ASAP (until my air exhange unit is up and running). Thanks for your time.
