A window basically will need shutters that cover the window. Window shutters consist of a frame with vertical and horizontal stiles and a material within, made of glass or fabric or solid panels or a combination of these. Window shutters provide protection against weather and control light within the room.
From within you may cover a window with blinds, curtains or drapes, each having its own distinct functional and aesthetic advantage. The process of selecting and installing the window covers is called window treatment. As much thought is given to aesthetics, interior design theme as much is given to its function and security.
A combination of walls of a room, within it the windows, will decide how a room looks like.
