KOUFALL Basement Window Curtains

KOUFALL offers a blackout valance designed to reduce sunlight while enhancing a transom’s appearance. The package includes one valance measuring 52 W by 18 L inches, crafted from soft blackout fabric. Its double header features a 2 cm top ruffle and a 7.5 cm (3 inch) header that facilitates smooth sliding. While primarily a valance, this option provides a lightweight, decorative solution for small transom openings, helping manage glare above doors or high windows without heavy installation requirements.
Features include blackout properties to minimize sun intrusion and a dual-header design to support easy operation. The product is well-suited for renters or spaces where a subtle, non-permanent treatment is preferred. Users should verify the actual mounting fit and consider pairing with compatible hardware for secure inside-mount installation on transom heights.
Achim Morningstar Cordless Light Filtering Mini Blinds

These cordless mini blinds are designed for light control with a 1″ slat size and light-filtering fabric. They minimize cords for safer homes and offer versatile sizing that can fit many small transom-style openings. The blinds are built to resist warping, fading, and sagging, contributing to durable performance in varied interior spaces. They provide inside, outside, or ceiling installation options thanks to hidden mounting brackets, making them adaptable to compact transom configurations above doors or short windows.
Key considerations include fit accuracy—these blinds run slightly narrower than stated—and the ease of installation with included hardware. The cordless design enhances safety for households with children and pets. While they are primarily light-filtering, pairing with a blackout liner (if desired) could improve privacy for semi-private transom spaces.
Achim Morningstar 30″ Wide Mini Blind

This 1″ slat cordless mini blind by Achim focuses on safety and simple installation. Like other Morningstar products, it features a cordless mechanism, making it suitable for higher, small openings found in transoms. The blinds are easy to handle and designed to resist wear over time, with hidden mounting options that support inside, outside, or ceiling mounting. For transom windows, this size set can be matched with precise window width measurements to avoid oversized gaps and ensure proper shade coverage.
LazBlinds No Drill No Tools Blackout Roller Shades

These cordless blackout roller shades from LazBlinds are designed for inside-mount installations with no drilling required. The 20″ W x 48″ H size is typical for some transom spaces where width is constrained and height is short. The design allows easy trimming to fit and provides complete blackout when needed. Key features include no tools installation, a compact profile, and safe, cord-free operation, which is valuable for high or awkwardly placed windows above doors or cabinetry.
LazBlinds 100% Blackout Roller Shades

Designed for total darkness and privacy, LazBlinds 100% Blackout Roller Shades use a polyester fabric with blackout backing. The no-tools-no-drill installation is ideal for renters or spaces where damage-free mounting matters, such as upper window inserts or transom areas. The shade’s cordless operation makes it safe around children and pets. While adjustable in width, the product requires careful sizing to minimize gaps for partial light control at transom heights.
Calyx Interiors Cordless White 1” Mini Blinds

Calyx Interiors offers a 1″ cordless mini blind with a focus on child-safe operation and adaptable mounting for indoor windows. With sizing guidance indicating precise width and height requirements, these blinds are suitable for smaller transom openings where a clean, uncluttered appearance is desired. The cordless mechanism reduces hazards and simplifies operation, particularly in high-placed windows that are difficult to reach.
Graywind Smart Arched Blinds

Graywind’s arched blinds are designed for nonstandard arched transom openings. The smart, cordless system uses a rechargeable Alexa-enabled motor that connects with Zigbee devices and supports routines, schedules, and voice control. This solution is ideal for decorative arched transoms that still require light control and privacy. The blinds can be motorized for single or group control of up to 15 units, offering flexibility in multi-window setups above doors or curved interiors.
Buying Guide: Key Purchase Considerations For Transom Windows
- Mounting Type: Inside mounts preserve the trim and provide a neat finish, but require precise width measurements. Outside mounts can cover sill or trim but may reduce glass area. For transoms, inside-mount options with shallow depths are often best.
- Light Control vs. Privacy: If you need complete blackout above doors, choose blackout fabrics or roller shades. For softer light, light-filtering options are adequate and safer for daily use.
- Cordless Operation: Cordless or motorized systems reduce hazards for homes with children or pets and simplify high-position adjustments.
- Size And Fit: Transom windows vary in depth and width. Verify exact measurements, including the height above the door, and consider products that offer trimming or adjustable width.
- Durability And Maintenance: Materials like vinyl or polyester-backed fabrics resist warping and fading. Easy-clean options help with high-traffic entryways.
- Smart Integration: For arch or unique shapes, motorized or smart shades with compatible apps or assistants (Alexa, Zigbee) provide remote or scheduled control for convenience.
- Installation Time: No-drill or simple clip-on options are ideal for renters or quick replacements. Ensure hardware compatibility with frame depth and surface material.
- Aesthetic Fit: Transoms often sit above doors or mid-wall heights; select a color and style that complements existing decor and trim work for a cohesive look.
