For superior energy efficiency and to conserve heat, energy efficient windows are made from materials which have a higher insulating value. Features include multiple panes of glass which are frequently provided a reflective coating.
Another label to look for is the National Fenestration Rating Council. This tag provides information about “entire window” energy variables. As the name suggests, a window’s entire energy value is expressed in Many values, including:
- U-factor, which measures heat reduction. Windows with a decrease U-factor are ideally suited to cold climates.
- Air leakage variable determines the probability of drafts occuring. The greater the number, the more probable the window will be drafy.
- The greater a window Condensation Resistance, the less likely you should see water condensing within multiple window glazes.
- Visible Light Transmittance is comparable to sunglasses; the greater the number, the visible light that passes through the window.
The energy efficiency of a window can be influenced by an invisible protective coating called an e-coating. Argon or krypton gas sealed between every layer further enhances the efficacy of numerous glazed windows. Many configurations of these variables determine the Energy Star score and so the most energy efficient window for your dwelling.
Also bear in mind that a window’s energy efficiency can also be determined by, among other things, the neighborhood climate, the orientation of your house, size and location of the windows, the way you use to heat and cool your house and the level of shading around the home.
Have you ever wondered why rooms with thick drapes tend to stay warmer in winter? If you are interested in lowering your family’s carbon footprint or just wish to help your people save a little money, then understanding how to jumpstart your windows is truly important!
