As people become more environmentally conscious, they’ve been looking for ways to make their homes more energy efficient. One thing people overlook is their windows. Their entire house can be more energy efficient by switching to energy-efficient windows. But what exactly are energy-efficient windows? Continue reading to find out.

What are They?

Energy efficient windows, also known as energy-saving windows, help prevent your heated or cooled air from escaping your home. That’s because the more air that leaks out of your home, the more you use your heating and cooling systems, and the more energy you use. Energy efficiency windows have increased insulation, which in turn, reduces your home’s energy usage, and makes your home more comfortable.

What Makes a Window Energy Efficient?

There are a few things that make a window energy efficient.


Low-E glass


Low-E, or low emissivity, glass has a transparent coating that minimizes the amount of heat passing through the glass while still allowing light through. This nearly invisible coating reduces the U-value of the glass, which measures how well a window prevents non solar heat loss or gain.


Double Glazed Windows


Double-glazed windows reduce all forms of heat transfer. Since they are considered high-performance windows, they use the same method to create certified energy-efficient windows. When combined with Low-E glass on at least one pane and argon gas in between, double-glazed windows provide the best thermal insulation.


Window Frames


All energy-efficient windows are accompanied by energy-efficient frames. For a window frame to be considered energy efficient, it must have a low u-value. Some of the best frames for energy efficiency are wood, uPVC, and composite aluminum. They provide advanced thermal performance.


Good Weather Seals


Hot and cool air can escape and enter through gaps and cracks around the window. To prevent this from happening, energy-efficient windows use good weather seals. As a result, your windows are less likely to leak air, and it doesn’t require as much energy to keep your home at a comfortable temperature.
