The need to veil the view has also reached interior rooms. In order to achieve a more open sense of space and light, glass is also recommended for partitions, whether in clear or matt form. Plenty of glass brings elation and brightness into internal spaces. People are used to the light that forms and draws spaces and directs motion. Views opening from windows play an important part in orienting in the room. With the aid of a mute wall and transparent glass surfaces one can create spatial landscapes with different scopes, and direct the mover. Reflecting glass surfaces have also given glass a contrary role– it prevents forward motion. Bulletproof glass enables the glazing of “fortresses” and embassies, but evokes controversial feelings with its openness and inaccessibility at the same time. Matt or painted glass may also function as a mute wall surface, indicating clearly that this is a wall.
