Energy efficiency plays a crucial role in keeping your energy bills as low as possible and your home comfortable. An often-overlooked component of energy efficiency in homes and buildings is the type of glass used in windows.
Windows can significantly impact heating and cooling costs, and with the variety of energy-efficient options available, it’s important to understand which types save the most on these bills. So, what kind of glass saves you the most on heating and cooling bills?
Energy Saving Glass Tip #1: Low-Emissivity (Low-E) Glass
Low-emissivity glass has a microscopically thin coating that reflects heat back into the room during winter and blocks unwanted heat during summer.
The coating allows natural light to pass through while filtering ultraviolet and infrared rays, which helps reduce the need for artificial lighting and protects furniture from fading.
The effectiveness of Low-E glass in reducing heating and cooling bills can be substantial—it can improve insulation values by up to 50%, significantly decreasing energy use in both summer and winter.
Energy Saving Glass Tip #2: Double and Triple Glazing
Another effective energy-efficient option is double or triple-glazed windows. These windows consist of two or three glass panes separated by an air or gas-filled space, which acts as an insulating barrier. Argon or krypton gas, commonly used in the space between the panes, offers superior insulation compared to regular air due to its higher density, which can be especially useful in colder climates.
Double glazing can cut heat loss by up to 50% compared to single-pane windows, while triple glazing provides even greater energy savings. Although triple-glazed windows may have a higher upfront cost, they can offer long-term savings through significantly lower heating and cooling costs.
Energy Saving Glass Tip #3: Spectrally Selective Window Films
Spectrally selective glass is coated with special materials that can reflect undesirable solar heat while allowing natural light to enter. This type of glass can help in reducing cooling costs during the hotter months by minimizing the amount of heat that enters a building. It’s particularly beneficial in areas with minimal shading or in homes with large south-facing windows.
Energy Saving Glass Tip #4: Choosing the Right Glass and Proper Installation
The choice of glass depends on several factors, including climate, window orientation, and budget. For example, Low-E glass is an excellent all-around choice for varied climates. Double or triple glazing can be highly effective in regions with extreme temperatures, while spectrally selective tinted glass is ideal for sun-facing windows in warmer climates.
While selecting the right type of energy-efficient glass is crucial, proper installation is equally important for energy savings. Poorly installed windows can lead to air leaks, negating the benefits of high-performance glass investments. Professional installation ensures that windows are airtight and properly sealed, maximizing energy savings.
