Window coverings that are installed on the wall or frame surrounding the window opening, rather than inside the recess, are readily available at a major home improvement retailer. This mounting style offers complete window coverage, potentially blocking more light and providing increased privacy. For instance, if a window recess is shallow or obstructed, this installation method presents a viable solution.
The benefit of this approach lies in its adaptability. It can make smaller windows appear larger and can conceal imperfections around the window frame. Historically, this mounting method has been favored for its ease of installation and suitability for various window types and sizes. It allows for greater flexibility in choosing blind sizes, as precise measurements of the window recess are less critical.
