Vertical blinds are at home in tall buildings, apartment buildings, older homes, and designer homes. These window blinds are best for windows that are wider than tall, but they also are a good fit for windows that are very tall. Vertical blinds also can add height to a window space.
Wide windows are difficult to dress with regular roller shades because when you get beyond a certain width, about 72 inches, you need to add a seam, support, or multiple shades to cover the width and avoid sagging. By using vertical blinds on those same wide windows, any sagging problem is eliminated, and the window will have added height from the window blinds extending above the window frame. Vertical blinds on windows are drawn to one side, and if mounted outside the frame, they allow full window visibility, and allow a complete view out the entire window. They are best for window walls, allowing the opening to be used.
Tall windows can be difficult to put regular window blinds in, because of the height and amount of slats that would be rolled up or down. Much better and easier to use are the vertical blinds. These blinds can add some width to the window frame if mounted outside, and the blind vanes would be drawn to one side. Vertical blinds provide the best privacy and light control on large or tall windows also.
In tall buildings, many architectural styles use huge windows, even walls that are glass. Vertical blinds are really the only proper solution when selecting window blinds, and with their straight lines add more features to what could be plain architecture. One problem may be the length of vanes, and there can be some side buckling on extra long vanes when lightweight materials are used, like vinyl. This can be overcome by using heavier materials, and fabric coverings. For extra long situations, fabric covered vertical blinds are best because they have more give and would not buckle.
Any time you have extra wide, or extra long vertical blinds, you are dealing with more size and more weight. Motorization is an answer to those potential problems. Mechanisms work easily and they operate smoothly. All motorization and pull systems and hanging parts are hidden behind a matching top head rail valance. With non-motorized vertical blinds, the operation of opening and closing and adjustments is done with a small wand hung to one side of the head rail.
Window blinds are wonderful for controlling light. By adjusting the angle of the vanes, you can allow full daylight into the room, close it off completely, or stop somewhere in between. You can bounce the lighting off nearby walls for a little multiplication of light in the room. For privacy, many of the adjustments provide plenty of privacy, and you do not have to have the blinds totally closed. Vertical blinds work better with side opening windows, and heavier blinds are less likely to blow around in the wind.
For darkening a room, the vertical blinds are good because they allow less light in between slats, or vanes, and it does not reflect off ceilings or floor coverings. This type of blind is good for room darkening, and will help insulate a room. If you have fabric covered blinds, they are the best at insulating, and wood blinds are also very dense and provide similar insulation effects when closed.
Vertical blinds are easy to clean, and do not collect dust like horizontal blinds would catch. Used in tall buildings, they take less time to keep dust free and clean. Overall, vertical blinds are at home in tall buildings, and anywhere window size or dimensions might be an issue.
