Bi-Fold Doors	Bi-fold Doors By far the most popular option for spanning large openings are bi-fold doors. With a variety of opening styles and options one of the main advantage of this type of door is that as well as being able to operate a standard single or double door you are also able to open up the whole area, creating a clear opening. These doors are ideal for lounges, conservatories or even kitchen areas as they really do help to bring the garden inside your home.
