In the winter when the sun is out, open the blinds to bring sunlight into the room, or set them so the rounded side faces the room to move warmer ceiling air closer to where it is needed.
Which way should blinds be turned?
If the window is on the ground floor, the blind should be closed slats up. Otherwise, people can see in from the floors above. For that reason blinds on an upper floor should close slats down. If you live in the middle, your best bet is curtains.
Should blinds be open or closed in winter?
By closing the blinds, you keep direct sunlight out of your home and reduce unwanted solar heat gain. Closing window blinds can also save energy in the winter. During cold nights, heat is lost through windows. Closing the blinds adds some insulation to the windows, reducing heat loss.
Can you see through vertical blinds at night?
As much as you can see outside through window covering in the daytime will reverse at night when lights are on and it is dark outside. However, if someone is against the window, a rough shadow may show. One product to be aware of is a mylar roller shade which reflects sunlight. Some have metal reflective backs.
Do blinds keep cold air out?
To effectively warm a room in your home during the winter months, consider investing in interior blinds. Blinds will absorb the sunlight, and they will offer insulation where it is desired. To do so, interior blinds can be closed all of the way. Outdoor window treatments can easily be lowered into place.
