Today in -15 C degrees I noticed that several windows have condensation on the inside in the lower corners, despite the low humidity inside 40%.
The windows are aluminum and wood with triple glazing with a warm edge. I am surprised that only 4 of the 20 windows are affected. Personally, I have also found that if you almost stick your finger in the corner, you can see cold air through the seal.
Is this a defect or is it inevitable and acceptable given the outdoor temperatures?
