Condensation on Anderson windows
There are several older Anderson windows in my house; 5 of them that tend to form condensation on the inside in cold weather. I've even had ice on them when it's very cold.
An Anderson rep was here to repair one of the windows that showed a pattern indicating the seal was compromised. He checked the windows that condensate but told me nothing was wrong with them. (They are still under warranty.)
None of the newer Anderson windows show this condensation problem.
Can anyone advise me what might be going on and if it can be resolved?
