Sliding glass doors are popular because they let lots of light enter rooms. But too much sunlight may be annoying. For light filtering, sliding glass door blinds are a great solution. You have many coverings for your sliding doors. Vertical blinds are the most simple and versatile option: They are made of fabrics, vinyl, wood and aluminum and customers can usually choose on which side the blind will stack (left, right, both). These sliding glass door blinds never interfere with door traffic.
Horizontal sliding glass door blinds may be uncomfortable if one blind covers both door panes because it won't let people pass if they are lowered: You would have to lift the entire sliding glass door blinds, which isn't good for privacy.
