The strong Velcro allows for easy detachment for cleaning, and the setup is designed to deliver a secure fit for 24″x48″ semi-circular arches. It’s a practical option for renters or spaces that require quick, tool-free updates.

The shade is designed for up to a 36″ radius semi-circle and prioritizes quick customization for standard arch windows.

AOSKY Cordless Roller Shade Blackout (23″ W x 72″ H)

AOSKY offers a cordless, child-safe roller shade with 100% blackout capabilities and a thermal backing to reduce energy loss through arches. The fabric is 100% polyester, and the built-in spring mechanism provides smooth operation with lift-and-stop control. For arch shapes, a width of 23″ and height of 72″ makes it suitable for various transom-adjacent windows, though installation alignment should consider the curved top portion for best results.
Changshade Arch Window Shades Blackout (36″ Radius)

Changshade’s larger-radius option provides a durable, blackout-capable shade designed for 36″ arches. The fabric remains easy to maintain, and the laminated backing supports privacy and energy efficiency. Like other Changshade offerings, it features tool-free installation and trimmed-fit customization to accommodate irregular arch shapes, making it a strong choice for larger transom-like arches.
Buying Guide: Key Purchase Considerations
- Fit and radius: Confirm the arch radius (6″–36″) and window depth to ensure the shade can be trimmed or mounted securely without gaps that let light leak around the edges.
- Light control: Choose blackout for complete darkness or light-filtering for a softer glow. Consider whether room temperature and noise reduction are priorities.
- Installation method: No-drill and adhesive Velcro solutions are ideal for renters or non-permanent setups. Tool-free options are generally easier but may offer less long-term stability than brackets.
- Material and durability: Look for reinforced backing (aluminum or foil) and durable fabrics. Non-woven or polyester fabrics are common; ensure cleaning and maintenance compatibility with your lifestyle.
- Color and finish: Light colors reflect heat and light, while darker shades can enhance perceived privacy. If installed in a bright room, a reflective backing may improve energy efficiency.
- Safety and edges: Cordless designs reduce hazards for households with children or pets. Verify that the mechanism meets local safety standards.
- Ease of trimming: Some shades are designed to be cut at home for a precise fit; verify available measurements and trimming guidelines before purchasing.
- Maintenance: Removable facings or detachment-friendly fabrics simplify cleaning, especially for hard-to-reach arch shapes.
Overall, choosing the right shade for transom or arch windows involves balancing fit, light control, and installation practicality. The options above provide a spectrum from full blackout to filtered light, with varying installation methods to suit renters, homeowners, and DIY enthusiasts. Consider the arch radius, desired level of privacy, and how often you plan to adjust light levels when making your selection.
