LP gas or any heating system , electric, Ng, oil, does not add humidity
on it own , if it does its emitting Co and you would be sick.
Humidifiers add humidity, cooking, showering, etc. Windows condense
because it is the coldest area of the house, poor designs have little
insulation value. Dual pane does not mean high insulation, CDF is
condensing factor, a rating Pella scores poorly on compared to Anderson.
You have not determined humidity is high and its not just poor glass or
a humidifier or tight house. If windows are sealed shut as you seem to
indicate than how do you open the casements. Start with a calibrated
analog humidisat, one you set-calibrate yourself, or a good digital and
see where you are. If you have a humidifier , turn it down till
Thanks for the replies, you have pointed me in some new directions to
look into for the cause of the humidity. I do agree that the windows
are not of the best design, but I do not have a humidifier nor do I
have a dehumidifier either. I really don't want to remove the windows
that are in place as that would be a real task. I pointed to the
condensation as one of the major problems. The other problem these
windows have is that they just do not insulate well at all and was
looking at something to use as a storm window type setup in the end.
Using the existing window as the storm window and a better insulating
window inside. I looked at replacement windows in vinyl as the windows
to place inside the current windows but am not sure that this would
work. I could remove the sheet rock in the window holes and place the
new window in the hole as close to the inside as possible and then use
trim to finish the window out. Of course using the necessary sealants
to insure an air tight fit.
