When the Pressure is On: Why Your Double-Pane Window Has Collapsed

When the Pressure is On: Why Your Double-Pane Window Has Collapsed

Between combatting constant humidity, annual hurricanes, and the sweltering sun, durable windows that offer enhanced insulation are all but a necessity for Florida residents. Thus, many have recently turned to the beautiful and cost-saving option that is double-paned windows.

Of course, even the best of options has their flaws.

And if you’ve invested in a double-pane window, there is one common complication you’ll want to keep an eye out for: Window collapse.

Defining the Double-Pane Window

Double-pane windows — also known as “double-glazed” windows, according to the National Fenestration Rating Commission (NFRC) —  are designed to better insulate a building from the inside-out.

And the way this is achieved? With gas.

Specifically, the two panes of a double-pane window are set slightly apart and then sealed to remain airtight, allowing space for a layer of gas to be injected in between. The combination of glass with gas is designed to both prevent indoor heat from escaping, as well as block excessive sun-related heat from entering.

Additionally, aside from offering optimized insulation and energy-efficiency, double-pane windows are highly-regarded for being both affordable and aesthetically-pleasing, making them an altogether popular choice for homeowners today.

Negative Pressure and What You Need to Know

Typically, companies will inject argon and/or krypton between the panes of glass to achieve the dual interior and exterior insulation, as the U.S. Department of Energy explains that both gases “are inert, non-toxic, clear, and odorless.”

However, the problematic potential for a window collapse occurs when the gas either leaks or begins to dissipate over time. As the gas escapes from between the panes, a vacuum is left in its place, otherwise referred to as negative pressure. This negative pressure can begin to bend and warp the glass, if not cause the panes to outright collapse.

And if you’re wondering how to tell whether or not your window(s) may be at risk of or have already collapsed, one telltale sign of negative pressure between the panes is that of condensation. 

Calling in the Cavalry

If you’ve noticed condensation between the panes of your commercial or residential windows — or if you know for a fact your windows are collapsing — the culprit of negative pressure is ultimately that of improper sealing or poor installation.
