Specialty Windows for Splendid Homes – Part 3: Glass Options for Specialty Windows

Specialty windows may be most striking because of their shape and size but window glass is also a big consideration if you want to make the most out of the window style because it takes up a big portion of the window. To take full advantage of form and function, make sure you look for specialty windows with:

Double-Pane Construction

Single-pane windows used to be the standard but that all changed as demand for energy efficiency grew. As being energy-efficient meant improving insulation in the home, boosting insulative properties in window glass became a focus, resulting in double-pane windows.

As its name implies, double-pane windows have two panes of glass. Having two layers of glass allows a window to stunt the transfer of heat, keeping indoor heat in and outdoor heat out, but this function is improved with the use of gas fills. Argon or xenon are better insulators than regular air so heat transfer is better kept at bay when gas fills are in place.

Low-Emissivity Coating

Low-emissivity, or low-E, coating works by filtering out heat from sunlight without impeding levels of natural light let in. This means a specialty window fitted with low-E glass prevents too much heat from being absorbed into the home and making it difficult to normalize indoor temperature while supporting daylighting efforts. This not only ensures your comfort inside your home but also helps you cut back on energy use by keeping your HVAC system from working doubly hard and reducing your dependence on artificial light during the day. UV light is also blocked out by low-E glass so it also helps protect your furniture from fading.

Low-E coating may be applied on any of the four surfaces of a specialty window: the exterior side, the two sides facing each other within the insulated space, and the interior or room side. Typically, however, it is applied on one of the two sides within the insulated space for best results.

Specialty windows have a lot to offer but to make the most out of getting one, you have to be mindful of the design, color, and glass option it will have. It’s always a good thing to know about windows yourself but you can always turn to a professional should you require assistance. To learn more about specialty windows, don’t hesitate to talk to your local window expert today.


"I was very impressed with Renewal by Andersen. They showed up in time and we received several follow up phone calls as the installation was being done as well as the sales representative stopping by to check in on the installation. The delivery/ installer was very professional. I would highly recommend Renewal By Andersen."
