French doors traditionally were manufactured of hardwood but French glass doors have become more popular. Even where the original design is still followed double layers of glass are used for insulation and protection against elements. French glass doors are used more for decorative purposes as the privacy offered is minimal. They are more popular with the younger people who want to let in more natural light or complement an exterior landscape or add a stylish and decorative touch to the area.
These doors impart a chic European flavour to the home but they are expensive and not affordable for many. French glass doors definitely add a touch of class to your home and many may consider it to be a wise investment as they increase the value of the house.
