What Makes a Window Energy Efficient?

Are you thinking about getting new windows in Braunfels, TX? If so, you have to do a bit of research to make sure you find the product that is right for you. There are a myriad of styles and ratings available to you. One thing you have to consider as you shop for windows is the energy efficiency. You need to look at the label, the frame and the glass in order to get a clear picture of the energy efficiency of a particular window.


The National Fenestration Rating Council (NFRC) conducts tests on windows and has established industry standards. Any manufacturer that participates in the program has to properly label their windows. These labels make it easier for consumers to understand the thermal performance of a particular product. You need to learn about the jargon used on the label in order to understand what it says. Almost any window replacement in Braunfels should come with this label.


Certain frame materials are more efficient than others. For example, metal frames make for poor insulators while wood, vinyl and fiberglass do better. Currently, vinyl and fiberglass frames are the best choice for energy efficient windows.


Double- and triple-pane windows use airspace between panes to create insulation. Add a Low-E coating to that glass and your window will be much more energy efficient. You need to look for glass that will be able to protect from sun and wind.

The Whole Is Greater

When it comes down to it, you need to find a window that has a lot of these positive features. A triple-pane, aluminum frame window is still going to have insulation issues because the frame is too conductive. You need to find a product that works with itself to keep your home energy efficient. As you search for new windows in Braunfels, TX, you should work with a window installation expert. He or she will be able to help you pick out the product that best fits your needs.
