Vertical blinds are at home in office buildings, apartment buildings, older homes, and designer homes. But for tall or oversized windows, vertical blinds are the way to go. Tall and oversized windows are difficult to dress with most regular treatments because when you get beyond a certain width, say 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, all of these problems are eliminated. In many buildings, many architectural styles use huge windows, even walls that are glass. Vertical blinds are really the only proper solution when selecting window treatments, and with their straight lines add more features to what could be plain architecture. Vertical blinds are easy to clean, and do not collect dust like horizontal blinds. Used in tall and oversized windows, they take less time to keep dust free and clean. Overall, vertical blinds are at home anywhere window size or dimensions might be an issue.
