01
Near-full-width opening
Because the panels fold and stack, a bifold can clear much more of the structural opening than a conventional two-panel slider.
Bifold doors / design benefits + motion engineering
Open the wall.
Keep the flexibility.
Bifold doors are at their best when the goal is not merely a big view, but a big opening. Linked panels fold and stack to one side so a room, terrace, restaurant or living space can change character in seconds.
Architect + homeowner view
Why choose
bifold doors?
The opening type changes the way a room looks and behaves before any individual piece of hardware is chosen.
02
Indoor-outdoor connection
When open, the boundary can become broad and social rather than simply a doorway - useful for entertaining, hospitality and garden connections.
03
Compact panel stack
Multiple panels gather into a relatively compact stack instead of requiring the full width of each panel to slide behind another.
04
Flexible everyday use
Many configurations can include a traffic or access leaf, allowing quick daily entry without opening the entire panel set.
05
Top-hung architectural options
Top-hung bifolds carry panel weight at the head, which can reduce visible floor hardware and support cleaner threshold detailing where the complete system permits.
06
Configuration freedom
Depending on the system, panels can fold inward or outward and be arranged in different counts to suit room layout, furniture and the desired stack position.
Best when
Large entertaining openings, restaurants and hospitality, family living areas, flexible room divisions and projects where the open state should feel as close as possible to removing the wall.
Design around
Panel stack location, head support, adjustment range, threshold and drainage, the number of moving joints and seals, and the greater amount of framing visible when closed compared with very large sliders.
Engineering view
What changes
the motion.
Once the architectural intent is clear, these are the mechanical relationships that determine whether the opening still feels good years later.
01
Top-hung load paths
Carriers and overhead structure can remove floor obstructions while placing different demands on the head track.
02
Carriers & rollers
Rolling hardware must carry load while allowing a linked panel train to move consistently.
03
Hinges & pivots
Geometry determines how panels articulate, stack and maintain alignment.
04
Guides
Guidance hardware controls the free end of the system and manages unwanted lateral movement.
05
Adjustment
Installation tolerances and panel settlement need controlled methods of correction.
06
Durability
Multiple interfaces operate every cycle, making material choice and wear behaviour important.
From the idea
to the hardware.
TITAN is CiiLOCK's specialist architectural doorware platform for bifold and top-hung door systems. Its dedicated site carries system choices, hardware detail, drawings and integration information.

Good motion still needs
a good system maker.
CiiLOCK develops hardware and motion technology. Local fabricators turn that technology into complete windows and doors. If you are an architect or homeowner, we can help connect the project to a suitable local contact where our network allows.
