Video: What You Need to Know about Window Condensation

Condensation happens when warmer, moist air comes into contact with cooler surfaces, like window glass on a winter night. Although it usually occurs during the coldest months, condensation can also happen in summer. This is why a cold beverage “sweats” on a hot day.

Any window company knows that condensation isn’t exactly good news because it can lead to water damage and mold growth. So, how can you keep it to a minimum? Renewal by Andersen® of Kansas City offers this explanation:

What Causes It?

Surprisingly, everyday living generates a lot of indoor moisture. Cooking three meals a day sends four or five pints of water into the air, and taking a shower adds another half. Regardless of its cause, though, the moisture source doesn’t have to be where the condensation happens. Vapor pressure forces moisture through different building materials, including plaster, wood, brick and cement.

Does It Indicate Bad Windows?

Condensation only becomes a window issue when it happens between the glass panels. When double-pane units excessively fog up inside, it may signal seal failure, which can affect the window’s insulating value.

However, its formation on the outer surfaces of the glass can actually indicate that your replacement windows are energy-efficient. It means that your units are airtight, locking in indoor air effectively.

How to Reduce Humidity

The best way to reduce the indoor moisture level is proper ventilation. Optimizing the airflow in the attic helps your home breathe out excessive moisture naturally. Venting gas appliances to the outside and covering the ground of the crawl space with a good vapor barrier also work.

Furthermore, our sliding, double-hung, bay, bow and casement windows can boost the natural ventilation of your rooms. We use argon gas filling (as an option) to help keep the glass of our custom-built units warm enough to resist condensation.
