Start with how the opening
should feel.
Windows and doors shape the view, the airflow, the floor plan and the way people move through a building. Compare the main opening types first. The hardware comes after.
Architecture first.
Mechanics underneath.
A homeowner may be thinking about a view, an entertaining area or better ventilation. An architect may be balancing opening width, sightlines, thresholds, accessibility and weather exposure. A fabricator eventually has to make all of that work.
CiiLOCK works in the layer underneath the finished window or door: movement, load, alignment, adjustment and control. Before those mechanics are chosen, it helps to be clear about what the opening needs to do for the building and the people using it.
Choose the motion
by what matters most.
There is no universally best opening type. The right one depends on what you value most: uninterrupted glass, a near-full-width opening, low operating effort, ventilation, sealing or a strong architectural gesture.
Different motions solve
different architectural problems.
The individual guides go into the trade-offs in more detail. This is the short version.
| Opening type | Strongest reason to use it | Often best for | Think about early | |
|---|---|---|---|---|
| Sliding | Large glass and no swing clearance. | Views, balconies, apartments, large glazed openings and indoor-outdoor living. | Thresholds, drainage, panel mass, screens, stacking and pocket access. | Explore → |
| Powered Sliding | Large panels with lower user effort. | Premium residences, accessible design and very large or highly sealed sliders. | Power, safety, controls, service access and predictable manual behaviour. | Explore → |
| Bifold | Near-full-width clear opening. | Entertaining spaces, hospitality, courtyards and rooms designed to transform. | Panel stack, head support, more joints and seals, and where the stack sits. | Explore → |
| Sashless | Minimal visible framing with top-and-bottom ventilation. | View-critical rooms, apartments, cafés and naturally ventilated spaces. | Balancing, fall protection, screens, weather rating, acoustics and cleaning. | Explore → |
| Hinged / Pivot | Direct access and strong sealing potential. | Entries, narrower openings, weather-exposed doors and statement pivot panels. | Swing clearance, wind, closer behaviour, load paths and structure. | Explore → |
Beautiful openings depend on
good mechanics.
CiiLOCK develops the mechanisms inside complete window and door systems — rollers, carriers, pivots, hinges, balances, handles, locks, closers, powered motion and the interfaces that keep everything aligned.
Fabricators and system manufacturers turn those mechanisms into the finished opening. For architects and homeowners, that means you can use CiiLOCK to understand the motion and then work with a local specialist to resolve the complete system.

From the idea to
a local specialist.
Homeowners and architects should not need to become hardware experts. Once you know the opening behaviour you want, a local fabricator or Motioneer can turn that intent into a complete window or door system.

The architecture
gets the credit.
The best hardware disappears into the experience. The door feels light. The stack lands where it should. The view stays clean. The window ventilates without visually becoming machinery.
