Why condensation forms Between a failed

Double-glazing Unit

When condensation between double pane windows forms it means the seal on

the insulated glass unit has failed. In this situation, why replace the unit when you

can fix it?

How Insulated Glass Works

With double pane windows, the insulating airspace in between the glass

panels reduces heat loss. Most modern windows have two panes of glass an inner

seal to protect against moisture and corrosion, and an outer seal to protect the

strength of the window. The seals hold a spacer in place

Why Do Seals Break?

For the most part insulated glass windows work extremely well. They can

withstand and handle all types of weather, including cold temperatures, heat, and

humidity, as well as repetitive open and close motions. With the double seal,

when one seal begins to break, the other can hold the line for a while. However,

as the window ages its components begin to break down, and the standard

lifespan of double pane windows ranges from 10 to 20 years.

Other than old age, there are two additional factors that affect seal breakage:

Water retention in the frame or improper drainage around the window.

 

Direct exposure to sunlight the more sun your window gets, the more heat

will build up causing the panes to expand, contract and eventually weaken.

Once the seal is broken, moisture begins to form between the panes, giving your

Windows a milky, foggy look.
