Arch Window Shade Radius 36 Inch Half Circle
Maritown’s arch shade expands from a rectangular 36-inch panel to a full half-moon shade with a 36-inch radius. The design uses double-sided adhesive to attach directly to the arched accessory and the window, eliminating the need for tools. The thick non-woven fabric filters 40-60% of light, reducing heat transfer and UV exposure while preserving privacy.
Arch Window Shade Radius 18 Inch Half Circle
This 18-inch version mirrors the 36-inch model’s adhesive-based installation, offering a practical solution for smaller arches or circular windows. The shade unfolds to an 18-inch radius half circle and uses thick non-woven fabric to filter light, improve privacy, and shield interiors from heat and UV rays. Easy, tool-free installation makes it suitable for renters and short-term setups.
Arch Small Window Shade Curtains 24×12
Jlong’s arch shade offers a versatile, easy-to-install solution for a variety of spaces, including circular and arched windows. The non-woven fabric filters strong light, reduces glare, and provides privacy without heavy installation. It’s designed for broad room applications—from bedrooms to kitchens—and emphasizes dust resistance and durability in daily use.
Arch Window Shade Radius 12 Inch
The 12-inch version provides a compact arch shade for small windows or decorative niches. Installation remains simple with adhesive-backed components, and the premium non-woven fabric delivers light filtering while preserving privacy. This option is a practical choice for tight arches or partial window coverings.
Graywind Smart Arched Blinds (Blackout Light Grey)

The system supports grouping up to 15 blinds and offers multiple schedules for flexible automation.
Graywind Smart Arched Blinds (Blue)
This arched blind variant emphasizes color variety while maintaining same core features: 100% blackout, cordless operation, and energy efficiency with a rechargeable Alexa motor. The blue option blends with modern decor and provides the same Zigbee-enabled voice and app control. It is designed for easy delayed or grouped automation alongside other smart blinds.
Graywind Smart Angled Blinds (Right Trapezoid)
Designed for right trapezoid windows, this Graywind shade offers 100% blackout, cordless operation, and a rechargeable motor with Zigbee connectivity. It supports routines, schedules, and position memory, enabling precise control of angled window light and privacy. The trapezoid shape expands the range of odd-shaped window coverage beyond arches.
Buying Guide: Key Purchase Considerations For Odd-Shaped Windows
- Window shape compatibility: Arch, half-moon, trapezoid, and other unusual shapes require either pre-shaped units or customizable, adhesive-based solutions. Consider whether you need a fixed shape or a flexible panel that adapts to the opening.
- Installation method: Adhesive-backed shades are quick and renter-friendly, while mechanical, motorized systems offer automation and long-term convenience. Determine if you prefer tool-free mounting or a more permanent fit.
- Light control and privacy: For half-circle and arched windows, assess the light-filtering capability (e.g., 40-60% filtering) versus full blackout. Cells or multiple fabric layers can improve insulation and privacy.
- Smart features: If automation matters, choose products with motorization, voice control (Alexa, Google), and Zigbee or hub-free setups. Check compatibility with your existing smart home ecosystem.
- Durability and materials: Non-woven fabrics are common for arch shades; they balance light filtration and privacy. Look for durable textiles that resist fading and daily wear.
- Size options and customization: Some brackets offer radius-based sizes (e.g., 12″, 18″, 36″), while others provide flexible dimensions. Ensure the product fits your exact arch or half-circle measurement.
- Maintenance: Consider ease of cleaning and whether the fabric is dustproof or machine-wwashable. Higher-quality materials may resist stains better and last longer.
- Safety: Cordless designs reduce risks for households with children and pets. If using motorized shades, verify safe operation and battery life expectations.
- Aesthetic for interior design: Colors and textures should complement decor. Neutral tones or soft greys tend to blend with most schemes, while bold options can serve as accent features.
- Warranty and support: Check manufacturer warranties and responsive customer service, especially for smart shades or custom-fit products.
