With a 36″ radius, they fit arched windows whose radii range from 6 to 36 inches. The design supports trimming for irregular arches, ensuring a precise fit. Each package includes accessories that prevent tilting or falling, and sturdy double-sided tape eliminates the need for complex tools during installation. The cordless, no-drill construction is ideal for quick updates to living rooms, bedrooms, or home offices with half-moon windows.
Maritown Arch Window Shade White 36×18 — Easy No-Drill Install
Maritown’s half-circle cell shade comes in multiple sizes, including 36×18 inches, with several color options. The no-drill honeycomb fabric features a built-in silver coating for effective light and heat blocking, while the reverse side remains white for a clean look. An arched fixed bracket supports stability, and double-sided tape simplifies application—trimmed to fit irregular arches without tools. This option is well-suited for rooms needing practical light control with a lighter installation process.
Myshade Arch Window Shade Black 72×36 — Bold Privacy
This variant from MYshade mirrors the blackout honeycomb construction but uses a black fabric to deliver a dramatic privacy solution for living areas or bedrooms with arch windows. The product retains the same radius compatibility and easy, tool-free setup via included double-sided tape. It can be trimmed for a custom fit, and the design emphasizes consistent room darkening along the curved pane, helping to reduce glare and improve viewing comfort in media spaces.
Touri Arch Window Light Filtering Pleated Shade — 60-70% Block
Touri provides a light-filtering option designed for semi-circle arches, offering approximately 60%–70% light reduction. The shade is easy to cut and install with included tape; the design is optimized for a 36″ radius arch, making it compatible with many standard half-circle windows. This solution balances natural light with privacy and is a practical choice when you want to preserve outdoor ambiance while diminishing glare on screens and furnishings. Consider this option if you frequently work in natural daylight and want a softer finish than a blackout shade.
Maritown Arch Window Shade White 24×12 — Compact Half Moon
This smaller arched shade from Maritown delivers a compact option for smaller half-circle windows, with sizes like 24×12 inches and a full set of colors. It continues to leverage the no-drill, double-sided tape installation approach, and the two-sided color design improves versatility for different rooms. The product emphasizes ease of fit, with trimming to match non-standard radii, and provides the same core benefits of privacy and light control in a space-conscious package.
Buying Guide
- Window radius and size: Ensure the shade radius matches your arch window (commonly 24″ to 36″). Some products specify compatibility across radii 6″–24″ or 6″–36″.
- Light control vs. privacy: Choose blackout cellular shades for maximum privacy and light blockage; light-filtering pleated shades soften daylight while reducing glare.
- Installation method: No-drill options with double-sided tape offer quick setups. Check if trimming is possible for irregular arches to avoid gaps.
- Color and backside: Some two-sided honeycombs have a different color on each side; a white backside can provide a clean look when viewed from the outside.
- Durability and maintenance: Non-woven fabrics and aluminum backing enhance durability and heat blocking; easy-to-clean surfaces minimize maintenance.
- Access and operation: Cordless or cordless-tape installations reduce clutter and improve safety in homes with children or pets.
- Aesthetics: Consider the room’s decor—white shades for a seamless look, or darker shades for dramatic contrast and privacy.
- Cost vs. coverage: For larger arches, a 72″ width shade may offer a single-piece solution, while smaller arches can benefit from multiple, modular panels.
When selecting window treatments for half-circle windows, balance fit precision, ease of installation, and the level of light control you desire.
