Design House Window

Modern windows are usually glazed or covered in some other transparent or translucent material. Windows are held in place by frames.[2] Many glazed windows may be opened, to allow ventilation, or closed, to exclude inclement weather.[3] Windows often have a latch or similar mechanism to lock the window shut.

The Romans were the first known to use glass for windows, a technology likely first produced in Roman Egypt, in Alexandria ca. 100 AD. Paper windows were economical and widely used in ancient China, Korea and Japan. In England, glass became common in the windows of ordinary homes only in the early 17th century whereas windows made up of panes of flattened animal horn were used as early as the 14th century. In the 19th century American west, greased paper windows came to be used by itinerant groups. Modern-style floor-to-ceiling windows became possible only after the industrial plate glass making processes were perfected.
