By closing the blinds, you keep direct sunlight out of your home and reduce unwanted solar heat gain. Closing window blinds help save energy in the winter since, during cold nights, heat is lost through windows. Closing the blinds will add some insulation to the windows, reducing heat loss.
Are blinds or curtains more energy efficient?
Curtains offer better insulation and soundproofing.
In warm weather, however, blinds beat curtains in energy efficiency. Because blinds leak more heat from a room, they also decrease indoor heat gain more efficiently in the summer, by around 45 percent, which can lower your AC bills.
How are blinds energy efficient?
Blinds will reduce heat gain in summer by reflecting the heat back out the window, particularly if the external surface is white or close to white. In winter, if the blind is well-fitted (roman blinds are a great choice for this job), the space between the blind and window traps still air to prevent heat loss.
Do blinds help with heat loss?
Window blinds—vertical (Venetian blinds) or horizontal slat-type (louvered-type)—are effective at reducing summer heat gain and reducing glare, while providing good daylight indoors.

Should you close blinds at night?
To let in a small amount of natural light, it’s best to turn your blinds down and close them. This allows some light to filter in creating a slightly diffused lighting condition. Blinds turned down also direct more light into the center of the room rather than the ceiling, creating a softly lit environment.
Does closing blinds keep house warmer in winter?
Tip. Closing your window blinds on hot summer days blocks the sunlight to keep your home cooler and reduce your energy use. Closing them on cold winter nights cuts down on heat loss, so your home stays warmer with less strain on your furnace.
Do blinds keep the cold out?
The thickness of the louvers also acts as a barrier to air transmission from the cold window to the inside of the house. The closer a blind or shade is to the window, the better it will perform as an insulator, so an inside mount blind or shade will provide the most protection from cold drafts.
What are the best blinds for keeping heat in?

Which way should your blinds face?
The direction — up or down — to close blind slats is a matter of personal preference, but if you want more privacy, tilt them up, with the rounded side facing out. With window blinds tilted up, passers-by can’t see in: The convex side faces the window, creating less space through which to view.
Does keeping blinds closed keep house cooler?
Closed blinds serve to deflect the sun (and so, heat) before it gets into the room, which reduces unwanted solar gain and helps to keep your home cooler in turn.
Should you open blinds before raising them?
The slats should be open when raising or lowering the blind. When opening a window behind your blind, always pull the blind up first – do not push your hands through the slats as this will damage the blind.
Why do flight attendants ask to open the window shades?
“From a safety standpoint, open shades help improve situational awareness,” says a rep from the Flight Safety Foundation. “For example, during an emergency evacuation, flight attendants or passengers need to be able to see outside to determine whether it’s safe to open and use an emergency exit.
Can you see through blinds from outside at night?
No, people outside would not be able to see anything of inside, not even movement close to the window, nor the shapes and outlines of things. They would, however, be able to see a diffuse glow of light if you have a reasonably bright light not too far from the window.
Closed in the inside up direction, blinds may not have as soft an appearance, but there is greater control of daylight entering the room. Sunlight and some radiant energy will be deflected upward and away from the room.
Which way should blinds face upstairs?
If the window is on the ground floor, the blind should be closed slats up. Otherwise, people can see in from the floors above. If, however, you are on an upper floor and the slats are up, anyone can see in from the ground floor. For that reason blinds on an upper floor should close slats down.
How do you make blinds block more light?
Why do my blinds let so much light in?
