Does the bifold door need a bottom track?
Bi-fold doors can be engineered in different ways. However, they all need a top and bottom track to slide smoothly.
Origin’s doors are bottom-run, which, from our experience, makes them more reliable and offers certain advantages:
- As the weight of the doors is at the bottom, it makes it less likely for one of the doors to drop.
- Top-hung doors need significantly more support above them, as that’s where the weight is concentrated. A builder would have to ensure there was enough structural support before installing a top-hung set of doors.
