Design Flexibility
Configurable Opening Layouts
Optimize space utilization with tailored stacking directions and integrated access doors.
Single-Direction Stacking
Three hinged panels slide and fold neatly to one side, offering a 90% unobstructed clear opening for standard patios and balconies.
Integrated Daily Access Door
Features a independent swing entry door for daily access, while allowing all four panels to fold away when full opening is desired.
Large-Span Dual Stacking
Engineered for wider building facades. Panels split and stack to both left and right sides to handle wide architectural expanses.
