We live in a 50 year old house and the two windows in the bedroom get condensation on the glass inside the room overnight. It is too the point where you can take a paper towel and it is soaking wet from just one payne of glass. They are not old windows either. We even took the moulding off the side of the window too see if there was some issue with no insulation, however the sheet rock goes up to the side of the window itself. We have even looked at the raidiator in the room to see if there was a pine hole leak and have found nothing on that end either. We just recently put an additional 9 inches of insulation in the attic since we only had three inches up there, however still no change on these two windows. We are at a loss as to what is causing this. It is also causeing mold to grow on the window at the part where the glass touches the white part of the window. Please help.
