Open the whole wall, then put it back.
01 — Overview
Engineered detail, not marketing copy.
Folding doors fail at the hinges and the bottom track. Ours hang from a reinforced top rail with stainless rollers, so the weight travels up into the structure instead of sitting in a floor channel full of sand. Panels stack tightly to one side, and the 75 series carries panels up to 3.2 m high for double-height living rooms.

04 — Design details
The detail is the difference.
Weight goes up, not down
Top-hung panels ride a reinforced head rail. The floor stays clear, which also means the door does not seize after a season of grit.
Stacked, not scattered
Panels fold flat against each other, taking about 90 mm of wall per leaf when open.
A threshold you can walk over
Low-profile and flush track options keep the indoor and outdoor floor levels close.
Lockable when closed
Multi-point locking on the leading panel, with concealed handles on the interior face.
