collasped windows and outside condensation
We have 18 yr old Anderson high performance windows. In March 2010 Anderson sent a tech out to repair the collapsed glass on all but 3 windows. The fix was the same that I have read online. My problem is that the last couple of weeks (July) we have had condensation on the outside on those windows that were fixed. Not everyday. Maybe 3x in 2 weeks. Today all windows were so bad you could not see out any of the windows. The condensation was so bad that it began running down the glass. I have been on the phone with the service rep then onto the sr. tech rep and up to an executive. I am told this is normal and the windows have not failed. This is the first time in 18 summers that this has happen. I understand(to a degree)about the relative humidity and dew point. Now I have read about what happens if 100% of Argon gas is used. Help! The executive from Anderson asked for three days to research the situation. Thanks in advance.
