One of the most annoying things that homeowners have to deal with is discoloration in double-pane windows. What causes clear windows to get color-stained surfaces?
Dirt
In many cases, discoloration is cost by accumulated dirt. Sure, the glass is vertical, but give it enough time, and dust particles will still end up clinging to its surface. It’s a good thing that this is a minor issue because discoloration caused by dust can easily be washed off.
Moss or Algae
Discoloration caused by moss or algae can be tough to get rid of because the colony can really anchor itself on the glass surface. Mold and algae tend to grow on the surface if there’s enough moisture clinging to it. This usually happens on the inner side of the glass panels where moisture that managed to seep in can’t evaporate properly and provide a breeding ground for moss and algae.
Moisture Issues
Sometimes, water alone can cause discoloration in double-pane windows. For example, with metal-framed double-pane windows, water stuck between the glass can cause the metal to rust, creating red or brown streaks. The same thing can be said about wood-framed versions, where the rot can cause stains.
The Answer: Moisture-Free Windows
As you can see, most of the serious signs of discoloration can be linked to having moisture stuck inside the glass panes. You can prevent this by getting replacement double-pane windows that have a more durable seal for keeping moisture out of them. Getting new windows also runs the benefit of improving your home’s overall energy efficiency, which is always a good thing.
