Custom Fixed Arch Cellular Shades – 25mm Fan-Shaped Honeycomb Blinds
Complete your arched window with a custom-sized honeycomb shade that follows a distinctive fan-shaped design. Nonwoven cellular fabric and an aluminum alloy rail provide a neat, fixed covering for semicircular windows.
Key Details at a Glance
Fixed coverage: This shade stays in position after installation. It does not raise, lower, or open and close like a standard operable cellular shade.
Installation Requirements
Confirm the window shape, mounting space, and fixing arrangement before ordering. Accurate width and height measurements are only part of checking the fit.
Check the Arch Shape
Measure the straight base and the center height. For a true semicircle, the height equals half the width. If your arch is flatter, taller, or irregular, send a front-facing photo and measurements for review.
Check Available Recess Depth
Measure the usable depth where the shade will be fitted. Confirm that the rail, fabric, and fixing hardware will fit within the available space. Ask us to confirm the minimum depth for your installation.
Confirm the Mounting Surface
Provide a clear photo of the surface intended to support the straight rail. Confirm the mounting method and required fixings for your window before placing the order.
Allow for Obstructions
Check for handles, hinges, trim, and inward-opening window parts. The fixed shade must fit without interfering with these components.
Cell size is not installation depth. The 0.98 in (25 mm) specification describes the honeycomb cell size; it is not a minimum recess-depth measurement. Confirm mounting clearance separately.
Custom Sizing & Product Specifications
Each shade is made to confirmed dimensions within the listed width range. Provide the actual window measurements and confirm the final order size, arch profile, and any size deductions before production.

How to Measure Your Arch Window
- Measure width (W). Measure straight across the base of the arched opening from one side to the other.
- Measure center height (H). Measure vertically from the midpoint of the base to the highest point of the arch. Do not measure along the curved edge.
- Measure the available depth. Record the usable recess depth and note any obstructions near the planned mounting position.
- Check the profile. For a true semicircle, H = W ÷ 2. If your opening has different proportions, send us a photo and both measurements before ordering.
- Confirm the order dimensions. Tell us whether your measurements are the window opening size or the required finished shade size. Confirm any deductions before entering the final order size.
Covering a Full Circular Window
A full circle requires two semicircular shades. One half covers the upper section and the other half covers the lower section. The two units meet across the center of the circular opening.
Semicircular Window
Required quantity: 1 shade
Provide the base width and center height of the semicircular opening.
Full Circular Window
Required quantity: 2 shades
Provide the full diameter and confirm the dimensions and mounting layout for both halves.
Geometry reference for a true circle with diameter D:
These are opening geometry measurements. Final shade dimensions must account for the confirmed mounting arrangement and clearances. The finished configuration has a center join; it is not one continuous circular shade.
Fabric Choices & Rail Construction
Blackout Fabric
Nonwoven cellular fabric with an internal aluminum foil layer for light-blocking coverage.
Light-Filtering Fabric
Softens incoming daylight while retaining the distinctive fan-shaped honeycomb appearance.
Sheer Fabric
A more translucent option for gentle light diffusion and a lighter appearance.
Aluminum Alloy Rail
A sturdy aluminum profile with a smooth electrostatic spray finish supports the fabric. A PVC insert holds the fabric securely in the rail.
Blackout describes the fabric. Light may still enter around the perimeter or at the center join of a two-piece circular configuration. Confirm the available colors for your selected fabric before ordering.
Frequently Asked Questions
Can this arch shade be opened or lowered?
No. This is a fixed, non-operable shade designed to remain in its fitted position.
What width can I order?
The listed custom width range is 11.81–29.53 in (300–750 mm). Send the width, center height, and a photo of your window so we can confirm the arch shape and final size.
Can it cover a completely round window?
Yes. A full circular window requires two semicircular shades combined at the center. Confirm the sizing and mounting arrangement for both halves before ordering.
Does 25 mm mean the minimum installation depth?
No. It is the honeycomb cell size. The available recess depth and the space needed for the rail and mounting hardware must be checked separately.
Is a 38 mm cell size available?
The specification range also includes 1.50 in (38 mm) cells. This listing features 0.98 in (25 mm) cells; contact us to confirm the 38 mm configuration before ordering.
Before You Place Your Custom Order
