Summer and Winter Window Condensation: A Comparison

Condensation is caused by warm and moist air coming into contact with any cold surface. In the context of windows, this happens whenever outside temperatures are low, resulting in the formation of water droplets on the window glass surface.

Summer And Winter Window Condensation A Comparison

This phenomenon is one of the many concerns homeowners face, regardless of hot or cold weather. But what’s the difference between condensation during the summer and winter?

Things to Know About Condensation

Whenever there’s a great difference between the temperatures inside and outside your home, expect condensation to form on your windows. It happens in both hot and cold weather, but it differs on which part of the window glass those water droplets appear.

Summer window condensation occurs on the exterior of windows. Fortunately, this doesn’t put your home or your health at risk because the problem is mostly visual. When outside temperatures drop in the fall and winter, condensation still appears, but on the window interior this time. This often results in moisture damage and other issues.

How to Solve the Problem

The problem of window condensation can be solved by taking a look at your home’s indoor humidity. It must be kept to a minimum for the most part, especially during winter. While investing in dehumidifiers and exhaust fans help lower humidity levels, replacing your current windows with ones that have energy-efficient features would be of greater help.

If you have single-pane windows, consider switching to double-pane ones. These are composed of insulated glass units to prevent condensation as well as an argon or krypton gas fill between the glass panes. This gas reduces convection between the panels can be reduced.
