Why Discoloration Occurs in Double-Pane Windows

Double-pane windows are considered an upgrade to traditional single-pane units because of their thermal performance. They help minimize heat or cold transfer from the outside, allowing for a cooler home in the summer and warmer one in winter – minus the high energy costs. But double-pane windows are also prone to discoloration, which is a typical warning sign of an underlying issue.

Why Discoloration Occurs in Double-Pane Windows

The Primary Reason Is Moisture Damage

Discoloration in double-pane windows occurs due to moisture damage resulting from high levels of indoor moisture. Take a closer look at your units, and you’ll probably discover black or dark-colored streaks along their surface. If you choose to touch these streaks, you’ll find them dry even if they’re caused by humidity. It’s also possible that you’ll see white, orange, green or brown mildew and mold on your double-pane windows. This, too, is a direct result of excess indoor moisture.

Dealing With Discolored Windows

Before having your double-pane windows dealt with, you’ll want to resolve your home’s humidity problem. Not only will this make the discoloration worse, it can lead to rot and poor indoor air quality, along with its associated health risks. You can make this possible through better ventilation, using an efficient dehumidifier or having your home’s plumbing system checked. Once the issue is fixed, you can then focus on your discolored windows.

While it’s possible to just replace the discolored glass and leave the window frames intact, the safer and more cost-effective is a replacement.
