Blinds can be concealed in the wall or ceiling, facing either the window or the room interior. Spaces requiring blackout blinds often use Blindspace side and bottom boxes. Bottom-up blinds can discreetly cover windows and gables, with or without side boxes. Installing blinds close to the window reduces gaps, improving privacy and minimizing light and warm air. Blindspace side boxes eliminate gaps for complete blackout. Account for protruding handles when configuring blind gaps near windows.
