A window is a clear hole in a wall or door that enables light to taste and, if it is not closed or sealed, air and sound. Windows are typically glazed or coated with other clear or semitransparent material. The windows are held in situ by frames that stop them from collapsing. They will typically be open, permitting ventilation, or closed in the event of inclement weather. The word window comes from the old norse word vindauga, that means wind and auga - the eye, or eye wind. In Norwegian and Icelandic form, this name has survived to the present day in an exceedingly very similar form. Many Germanic languages have adopted the Latin word opening to explain a window with glass - Windows Doors London In English, the word fenester was used until the top of the mid-eighteenth century and in window joinery it is still wont to describe window solutions within the facade. The windows in their primitive type were simply an easy hole in the wall. Later, the windows began to be coated with various materials, that principally served as decorative things. They were, maybe, animal fur, cloth or wood.
