Tilt & Turn Window
Dual-action sash for secure ventilation and full inward opening.
Custom aluminum windows, sliding systems, bi-fold doors and pergolas — configured by millimeter, finish, glazing and real opening behavior.
Designed around proportion, movement and the way a space actually opens to light, air and landscape.
Frame, sash, glazing and hardware — engineered as one system.
Multi-point locking and concealed hinges.
Double glazing, warm-edge spacer, EPDM seals.
Configure yours below — size, finish, glazing.
The configurator is not a generic visualizer. Every system has its own frame logic, panel count, hardware behavior and dimensional range — from a tilt-and-turn sash to a folding wall or rotating pergola louvers.
Select any product to open it directly in the live configurator. Each system has independent dimensions, finishes, glazing and movement controls.
Dual-action sash for secure ventilation and full inward opening.
Large glazed panels with controlled vertical movement and minimal framing.
Multiple aluminum leaves folding compactly to clear the opening.
Large-format insulated glass panels moving smoothly on low-profile tracks.
Configurable panel count and stacking direction for wide openings.
Rigid aluminum structure with rotating motorized roof louvers.
Aluminum frame with retractable textile roof and integrated lighting.
Minimal-frame interior sliding glass partition, up to 5 m wide.
Frame depth, panel division, track position, sash clearance and hardware are treated as part of the architecture. The live model responds to dimensional changes instead of only changing a number on screen.
Choose a system, change physical dimensions, finish, glazing and panel logic, then scrub the movement control to inspect the opening behavior with material reflections, hardware, tracks and depth cues.

Use the configurator to define the system, then send the selected dimensions and finish to THE WEST for engineering review and quotation.
