Are Your Double-Pane Windows Showing Signs of Discoloration?

Whether you have classic casement windows or picturesque picture windows, double-pane windows offer a great many benefits for any home. These types of windows are designed to reduce the amount of heat transmitted by the glass panes, which helps improve your insulation and keeps your home warm during the colder seasons and cool in the hotter ones. Double-pane windows accomplish this by using a small layer of inert gas sandwiched between, as its name suggests, two glass panels. Because they’re built differently from other types of windows, it’s important to be familiar with the common signs that could mean problems with its performance.

One telltale sign of a problem is discoloration. But what causes this issue, and can it be fixed?

Too Much Humidity Indoors

When your interiors have moisture-problems, your double-pane windows are the first to be affected. Too much moisture promotes the growth and spread of mold and mildew, which can show itself as streaks of black, brown, yellow or even white across the glass panes. These growths are often on the inside, which means you can’t feel them if you run your fingertips across the streaks.

Resolving Moisture Problems

Discoloration caused by moisture problems can be repaired. However, without addressing where the excess humidity is coming from, you may need to repair this issue frequently. In some cases, a full replacement may be necessary to ensure that your windows are sealed properly and airtight, which could be the root cause of the problem. Otherwise, consider using a dehumidifier to help control moisture levels in your home.

Related Issues

Excess moisture can also be coming from other sources, such as clogged or leaking gutters, high-moisture activities like cooking or bathing, or even water penetration on your roof. With new windows, replacing the style of your windows can also be helpful. Consider operable styles like casements, double-hung or sliding windows to promote air circulation indoors and keep your humidity levels in check.
