Should blinds be up or down?
Beside this, should window blinds be up or down?
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.
Additionally, which way should blinds be placed at night?
Our Recommendation: Position your blinds in the down position in the evening to block as much light as possible and provide the most privacy. During the day, position your blind slats in the up position. This helps prevent UV damage. During the day, position your blind slats in the up position.
Sheer curtains offer little during the day and almost none at night. The moment the sun goes down and lights come on inside the house, sheer curtains can completely expose you to outsiders. They allow just enough light to pass through and are strong enough to offer some semblance of privacy.
