Increasing electricity costs and the practical benefits of eco-friendly living have made energy-efficient windows more of a necessity these days. That is why homeowners are more inclined to use high-performance and energy-efficient building materials, especially when it comes to windows.
Here are the answers from Renewal by Andersen® of New Jersey to some frequently asked questions about energy-efficient windows.
A: Insulated glass units (IGUs) have two panes of glass separated by an inert gas. IGUs are also called double-glazing or double-pane glass windows. Most modern structures use insulated glass on their windows and doors.
A: Low-E glass has a transparent coating that decreases the transmission of UV rays from the outside, while allowing enough light to pass through. If you’re in the market for replacement windows, make sure they have a low-E coating — it’s worth the extra cost.
A: R-value is typically used when determining the insulation value of walls and ceilings. Meanwhile, U-value is used to indicate the insulation rating of windows and other fenestration products. A higher R-value means the walls and ceilings are better insulated, while a lower U-value means that a window can do a better job of keeping heat and cold out.
A: The ability to seal an inert gas between the panes of glass has been made possible by advancements in window technology. Argon gas is a better insulator than air, so it is commonly used by manufacturers to improve the thermal efficiency of windows.
