When choosing options for your replacement windows in Northbrook, IL you might think the glass is just glass. But window technologies have changed. There are several features to consider when choosing the glazing options for your new windows. These options impact the look, comfort, efficiency, and functionality of your windows. Here is what you need to know about these technologies:
Number of Panes
How many panes of glass do you want between you and the elements outside? The standard for most insulating glass units (IGUs) is two. But you can also get three or four panes of glass. Each layer adds extra protection, but do you really need so many? Two panes of glass usually provide the best value. At the very most three panes of glass can offer better protection, but usually in colder climates. And for many homeowners, the added cost of the third pane of glass is not worth the slight increase in energy savings.
Multiple panes of glass have a small space, and sandwiched between them isn’t ordinary air. Most manufacturers pump a noble gas into the space and seal it in place. The most common gasses include argon, krypton, and xenon. These have a higher density than normal oxygen and slow down heat transfer for improved insulation. Argon is the most common, krypton is one step up and works better in small spaces, and xenon provides the best insulation and works for larger expanses of glass.
Colored Window Tints
Next up are tinted windows. Common colors include grey, bronze, blue, or green. These special coatings can absorb as much as 45% or solar heat gains. They also cut down on visible light transmittance, reducing glare inside the home.
In warm climates manufacturers use special coatings on the outside surface of windows to help bounce sunlight away from the windows. This keeps unwanted heat from the sun outside. Common colors for these tints include silver, gold, and bronze. But like colored window tints, with reflective coatings, you lose visible light in addition to heat transfer. Homes with reflective coatings often look darker inside.
Low-E coatings are the technology of choice for many homeowners. Manufacturers apply ultrathin layers of metallic oxide to certain surfaces of the glass. The location of the coating will dictate the type of performance. For example, a low-E coating applied to the inner surface of the outer pane will stop radiant heat from coming inside. But a coating applied to the inner surface of the inner pane will trap radiant heat inside instead of letting it escape. Best of all, these special coatings still allow high levels of natural light to pass through the glass.
