What’s the Difference Between Winter and Summer Condensation?

Window condensation that occurs in the summer is caused by different factors than window condensation in the winter. Today, Renewal by Andersen® discusses the difference between summer and winter condensation on replacement windows.

Whats the Difference Between Winter and Summer Condensation

Seasonal Condensation

In the summer, condensation appears on the outside of the windows, whereas during the winter, it forms on the inside. Summer condensation is purely cosmetic and poses no risk to your windows or home. The only real downside of summer condensation on replacement windows is that it interrupts the view. 

Winter condensation, however, can be destructive if left unaddressed. Since it forms inside the windows, it creates a breeding ground for mold. Moisture retention can also cause damage to wooden components of your home.

What Causes Window Condensation?

Condensation in winter occurs when the warm air circulating inside your home comes into contact with the cooler surface of the windows. This can be a result of poor insulation, a faulty thermostat or simply doing a lot of cooking or laundry.

You can minimize winter window condensation by investing in a high-quality window replacement. Our windows are made from Fibrex®, a composite material that retains its rigidity and stability in all climates.
