it is like when you put a glass of cold water outside in a humid day
in the summer. how can I fix that? i thought putting humidifier would
help but i also thought humidifier should only be used in summer time
not winter.
please advised and thanks for all of you.
Mine do that sometimes. It happens when the temperature of the glass
gets down to the dew point of the air in the house.
In winter, a heat exchanger might be more practical than a dehumidifier.
Fogging is more likely when the glass is colder. I'm more likely to get
it if I close blinds and curtains, and in unheated rooms.
Hmmm
If seal is in good order it wouldn't do it. If humidity is too high
inside it can do do it on inside facing glass. Think your window seal is
compromised. Maintaining proper humidity level inside is important
for health, energy saving, commfort.
Oh, I see. I took "inside them" to mean the surface facing the interior
of the house. A flower box would be outside a window and a candle inside.
