Exterior window coverings, readily available from major home improvement retailers, are installed on the wall or frame surrounding the window opening, rather than inside the recess. This installation method offers advantages in situations where there is insufficient window depth or when an unobstructed view is desired when the blind is fully raised. For example, these window treatments can cover an entire window, including its trim, providing a unified aesthetic.
Employing this installation technique can create the illusion of larger windows and prevent light leakage around the edges when the blinds are closed. Historically, this method was often used in older homes where window frames were not uniformly sized or where interior space was limited. Furthermore, it provides an opportunity to coordinate the window covering with the surrounding wall color or decor, enhancing the overall room design.
