French doors are interior doors of light construction, usually installed in pairs, with divided glass panes extending for most of their length. They are prized for their visual grace and their ability to transmit light between spaces even when in closed position. Many are choosing French doors because they add a lot of style to a living or dining room with the open-air look.
French doors can open up a room to the outside. French doors are distinguishable because both sides open as opposed to only one. A door is a generally floor-length opening in a wall. Doors are nearly universal in structures of all kinds (especially houses and other buildings), allowing passage between inside and outside, or among internal rooms.
A French door is a door that has multiple lights, the full length of the door. Traditional French doors are assembled from individual small pieces of glass and mullions. French doors made of double-pane glass (on exterior doors for insulation reasons) may have the decorative grill embedded between the panes. The decorative grill may also be superimposed on top of single pane of glass in the door. French doors can also have decorative patterns cut into the glass for an elegant touch.
French doors incorporate an outdoor deck or patio into your living space. If you have a beautiful patio, you certainly want immediate access to this area.
