How To Toe And Heel Our Bi-folding Doors

Bi-folding doors are heavy, and although the dead weight is supported on the hinge side when it is opened, there is nothing on the lock side to support the weight. Without employing the procedure of toeing and heeling, the door will, sooner or later, 'drop' on the opposite side. To stop a door dropping, the glass itself has to be braced diagonally corner to corner by the insertion of plastic packers placed in the gap between the glass and frame, behind the glazing beads - around 150mm from the corner edge.

It is imperative that a bi-folding door is correctly toe and heeled first time. The sealed unit needs to be packed in such a way that the packers can literally support and hold the glass sealed unit in place, even without the use of the glazing beads and gaskets. This is done to ensure correct and sustained operation of your doors. The first sign of a door that has not been correctly installed is that the locking mechanism is not working as easily as it once did, or not at all.

The concepts shown in this video can be applied to toeing and heeling not only all the panels on any configuration of bi-folding door
but can also be applied to any door or window. Download our bifold installation manuals for more info »
