We Recommend:
Pick 1 1/4 inch cells for larger arch windows. Use 9/16 inch cells for smaller arches. Cell size affects how they look.
Non- Perfect Arch Styles work great if your arch is not a perfect half circle. Ask about options if your arch is unique.
Considerations:
Arch windows are custom-fitted. Measure carefully or contact our team for guidance on sizing.
Smart shades need the Bali App to pair with your phone. Gateway device required for smart home integration.
Cell size selection affects both appearance and energy performance.
Optional Upgrades:
Non- Perfect Arch Styles: Custom solutions for arch windows that are not perfect half circles. Ideal for unique architectural shapes and irregular window geometries.
Child Safety:
Bali Blackout Cellular Arch Shades are designed to exceed WCMA (Window Covering Manufacturers Association) safety standards. Cordless operation means no entanglement risks. Perfect for homes with children and pets.
