Click for flash video on professional french door installation with Bob Vila

French doors appear to have originated in France at the latter end of the Renaissance period of art and architecture, with a growth of popularity arising in France and Germany, circa 19th century and continuing through todays ever growing interest in these interior or exterior glass door applications. French Doors were first used as large windows that reached down to the floor,and opened onto small balconies. They were used to allow more natural light to flow from room to room in your home before the days of electricity. As time went on the doors and the balconies both got larger. Originally designed to allow natural light to flow from the outer, more sunlit rooms, into the adjoining interior rooms, these doors still not only have purpose, but also have become focal points of beauty in our offices and homes.
