Window treatments help with a home’s energy efficiency by providing insulation, controlling solar heat gain, and by using natural light to reduce the use of electric light (called daylighting), which saves energy. Here’s a look at each—and how they help create your comfort zone.
Providing insulation—winter/cool climates
In winter, or if you live in a cool climate, window treatments help insulate at the window, preventing heat from escaping and keeping a room warmer.
Open your window treatments during the day so that free solar heat from direct sunlight will warm your home.
On cloudy winter days, close your window treatments to add an insulating layer to your house that will keep warm air in.
At night, close your window treatments to add that insulating layer.
Controlling solar heat gain—summer/warm climates
During the day, close your window treatments to prevent the sun’s harsh rays from heating up a room, keeping it cooler (so your A/C doesn’t have to work as hard).
At night, keep your window treatments closed to keep the cool air in.
Natural light illuminating a room can make it more inviting, and may even boost your mood at the same time. You can maximize natural light with window treatments that draw it into a room, reducing the need for electric light, which reduces energy use.
