To enjoy more comfortable indoor temperatures and lower utility costs, be sure to invest in windows with energy-efficient glass. All glass packages might look the same at first, but each option offers varying levels of performance, so be sure to pick what best matches your needs.
Glass makes up most of your window structure, which also makes it the most important component in terms of energy efficiency. Its clarity and its insulation properties can significantly affect performance against the elements.
To be sure your window replacement project boosts your energy savings, it needs to have the following:
- Low-E Glass Coating – Unlike traditional windows, modern window replacement units come with low-emissivity (low-e) coating to filter out and help minimize the impact of UV rays and infrared light. This advanced coating allows necessary heat into the home, while keeping out excess energy to prevent overheating your space. And to keep the home bright and cheery, low-e glass allows visible light in.
- Double-Glazing – It’s been proven that windows with double or multiple layers of glass are more energy efficient than single-pane units. These windows have a space in between the panes to help reduce thermal loss and minimize the risk of overexposure to the sun’s heat.
- Gas Blends – For superior window insulation, energy-efficient units make use of gas blends in between the glazing. Some of the most common gases used are argon and krypton. These are the most ideal filling substitute for carbon dioxide and freon, which can cause seal failure and discoloration in windows.
- Weatherstripping – This vital component keeps the window insulated and protected against the elements. Poor weatherstripping can result in drafts coming in and energy leaking out. There are many types of weatherstripping materials to help improve your window’s performance, such as vinyl tension seals, foam-reinforced felt, bulb seals, and more. When used correctly, weatherstripping can help minimize air infiltration and be a significant factor in your overall energy efficiency.
For your windows to be effective, they must be installed correctly. Watch out for the last part of this three-part blog series in which we discuss the important characteristics homeowners should look for in a window installer.
