All of our windows, including our gliding windows, come with dual-pane glass as a standard option. This means there are two panes of glass with an air space in between. The air space is filled with an argon-gas blend. If you want to boost efficiency further, triple-pane glass, the most insulating glass of all, is also available as an option with E-Series Gliding Windows. Going for triple-pane glass can be a great choice in northern climates.
Our windows also come with a low-emissivity coating as a standard option. There are various types of Low-E coatings that can help a window perform better in different climates. However, Low-E4® glass has the coating combination that will work in most climates because it helps keep a home comfortable through the seasonal extremes of winter and summer.
So, when selecting the best glass option for your sliding window, consider whether a specific Low-E coating will make a difference in your climate. Otherwise, you can rest assured that the standard options have already been selected to optimize your window’s performance.
