Notable Features of Energy-Efficient Windows

Energy efficiency should be a priority when planning a new window installation. Old, inefficient windows can account for a huge percentage of your home’s heat loss and heat gain during winter and summer. When looking for energy-efficient windows, check for the following features:

Multiple Panes

Energy-efficient windows have at least two panes separated with a gas-filled space to boost insulation and thermal performance. Some ENERGY-STAR®-certified window products even have more than two glass panes for better energy efficiency and increased impact resistance.

Window Glass

Local door and window installation contractors recommend energy-efficient windows with low-emissivity (low-E) glass. Special coatings on the glass interior and exterior help keep heat inside during winter and outside during summer by reflecting infrared light. They also reflect ultraviolet light, protecting your furniture and other interior fixtures from fading.

Gas Fills

The space between the window glass panes is filled with an inert gas such as argon or krypton to increase the window’s insulating capacity. These odorless and colorless gases are used by manufacturers because they help slow the transfer of heat, which is a vital requirement for energy-efficient windows.

Warm Edge Spacers

These components separate the glass panes of energy-efficient windows at a precise distance, sealing off the air cavity between each one. To better reduce heat transfer through the windows, non-metallic and metal/non-metal hybrid spacers are used to insulate the edges of window panes.
