Condensation usually appears on your windows in winter. However, the same thing happens during the summer months. Renewal by Andersen®, one of the top window contractors in the area, explains how and why it occurs during this time of year.
Humidity levels rise when we rely on your heating system for comfort during the winter. Warm indoor air then comes into contact with cooler surfaces around your home, including the window glass. The difference in temperature inside and outside your home causes the interior part of your windows to “sweat” or form water droplets.
Condensation on windows in the summer is also common for the same reason but in reverse. As the weather heats up outside, the indoor air becomes much cooler thanks to air conditioning. In this instance, the “sweating” happens on the outside of the windows. It is similar to what happens when you leave a glass of cold water at room temperature for a few minutes.
Window condensation isn’t always a cause for concern. In fact, it only means that your windows are in good condition and doing their intended function. Energy-efficient replacement windows have low emissivity (low-E) glass coatings that keep the exterior and interior sides at the same temperature as the outdoors and indoors, respectively.
The only time window condensation becomes a problem is if water droplets appear from between glass panes. It is an indication that the seals on the insulated glass unit have failed, reducing the windows’ efficiency. In this case, get in touch with a reliable contractor for window replacement.
