What is a window? It seems an obvious question. By general definition a window is an opening fitted with glass that allows light into a room. Such designs go back to ancient times, when wealthy Romans started installing paned openings in their homes. The first clear glass panes were introduced in the late 3rd century CE, when the glassmakers came up with a method that involved blowing a cylindrical bubble of glass and then slice it lengthwise. But windows don’t necessary require glass to earn their status – even today, Japanese homes often use paper in stead of glass and so they go back to our very beginnings, when humans began building their homes. Mankind had moved on and today there are many types of windows:
