What is ‘window’? According to the Miriam-Webster dictionary, a definition of window is: “an opening especially in the wall of a building for admission of light and air that is usually closed by casements or sashes containing transparent material (as glass) and capable of being opened and shut”. And I believe this definition is a global definition, in every language. However, the interpretation and solution could be different depending on the location and culture.

A practice that is still part of the Arabian traditional architecture up to this date.
