Whether you had a professional window installation recently or a decade ago, your windows are likely fitted with some form of thermally sealed glazing. These insulated glass units (IGUs) are different from the average single-pane window. However, even if your windows are modern and innovative, window seals still break down over time. Before you can check if your window seals have failed, you need to understand first what they are.
How Windows Are Sealed
Although single-pane windows have been around for a long time, they don’t really use any modern sealing. Over time, the glass becomes loose within their frames when the glazing putty becomes loose. Most modern windows are sealed when two or three layers of glass are assembled and separated by either a partial vacuum or being filled with an inert gas such as krypton or argon. This makes them IGUs, which can also be coated with a heat-reflective material depending on your preferences. This can help keep your home cooler during the summer months, but it won’t be effective if your IGU’s window seals are no longer intact.
Checking a Broken or Failed Window Seal
The gas sealed within an IGU will leak at a rate around one percent per year. This doesn’t mean you’ll need to spend for a yearly window installation; it’s actually a natural occurrence because of the different pressures between the gas inside your window and the normal air outside. However, your window seals can still fail prematurely.
One visible sign that indicates your seals have failed is noticing that your window looks a bit distorted, as if it’s bowing toward the center. This means the gas that filled up your window has already leaked and is filled with air. If your windows look tinted or even foggy, then it’s another indication that your window seal is broken. If left unaddressed, your energy efficiency becomes affected and you’ll end up consuming more energy to keep your home comfortable than what’s needed.
