Purchasing the right type of window can help a homeowner save on energy bills. However, there isn’t just one type of Energy Efficient Windows in Louisville KY. Understanding the different options can make it easier to choose just the right one to maximize savings on the utility bills.
Frame Type
For the most energy efficiency, look for a frame with a high U-factor. Metal frames, such as those made of aluminum, are among the worst options for insulating because they conduct heat very well, but they don’t require much maintenance. Adding an insulating plastic strip, called a thermal break, between the frame and the sash can help improve this. Better options include fiberglass, wood, vinyl or composite frames. Wood frames tend to need regular maintenance and are susceptible to rotting, so those looking for an easier option and those who live in very wet areas might want to opt for fiberglass or insulated vinyl frames. Composite frames are also a good alternative, as they are more stable and resist decay and rotting better than wood frames.
Insulated or Gas Filled Windows
Certain types of glass are more energy efficient than others. Look for types of windows that are labeled as having low-E glass. These include windows that have multiple panes of glass that are sealed with a space in between to offer better insulating properties. Some even have a gas fill, such as krypton or argon, which further improves the insulation compared to simply sealing air between the panes of glass. While triple-paned glass won’t necessarily increase benefits for all homes, it might be worth it in places where the climate is particularly harsh.
Tinted Glass
To make the window even more energy efficient, consider a tint. There are various types of tints that can help, depending on where a person lives. For example, heat-absorbing tints can be helpful for people who live in hot areas with a lot of sunlight. Reflective coatings help limit the light coming in the window, which minimizes fading of the belongings inside, but also helps somewhat reduce the amount of heat passing through the glass. A potentially better option for some homes is a spectrally selective coating, which helps keep heat from being transferred while still allowing light to come inside.
