Condensaton and icing on new E-Star windows
Hello, I have a new house (under 1 year old) that is E-Star compliant with double-glazed thermopane casement windows. Now that the weather has turned colder I am seeing condensation and icing along the bottom of the interior (room) side of most of my windows. The humidity in the house is pretty low. Is this indicative of defective windows, and how can I make a more accurate determination?
Thanks in advance,
Ed

Ed,
You don't have defective windows; you are simply seeing a demonstration of physics in action.
To get rid of the condensation, add an exterior storm window or lower your indoor humidity level.

Ed: "The humidity in the house is pretty low." Define "pretty low", pls. Are the windows outies in real thick walls? Do you have curtains or shades drawn a lot of the time?
