If the glass temperature in below freezing, then frost will form on your windows.

These grooves are formed in a process similar to canyon formation.

Vinyl window frames have a higher coefficient of expansion resulting in greater long-term stress on the double-pane assembly, and a higher failure rate. Ideally, we want humidity levels to be at around 50%. Plants release moisture into the air as they grow, … This prevents heat escaping, and will reduce your energy bills, but in doing so it will create a considerable difference in heat from one side of the glass to the other.
