Leaves fold in pairs from the frame. Where an odd number fold to one side, the leaf furthest from the frame on that side is a master door: it opens on its own, like an ordinary door.

Choosing a layout
Viewed from outside, the leaves fold to the left, to the right, or split between the two sides, and the whole set opens in or out. The leaves fold in pairs from the side of the frame. A stack with an odd number of leaves ends in a master door: the leaf furthest from the frame, which opens on its own, so it's the one you use day to day. The designer draws each layout from above, like these.
No master door. With 2 or 4 leaves all folding one way, or 2 folding each way, 2 doors must open at once. The designer warns you when you pick one of these layouts.
Before you order
Measure the opening
Measure the opening brick to brick, and from the solid base up to the lintel, in three places. Take the smallest figure and deduct 10mm each way. That's the overall size we make, cill included. The bifold measuring guide takes you through it step by step.
