Product Information
True darkness, beautifully tailored.
Our 9/16" Classic Single Cell Blackout Cordless Shades combine an opaque blackout fabric with an insulating honeycomb cell, so the same shade that darkens a bedroom also keeps it warmer in winter and cooler in summer. The 9/16" medium cell gives a clean, tailored line on the window, neither too fine nor too bulky.
Made from 100% polyester spun lace non-woven fabric and finished with a color-coordinated vinyl headrail and bottom rail, they are built to look considered rather than purely functional.
Key Features and Benefits
- True Blackout Fabric: Opaque honeycomb fabric blocks incoming light through the shade for genuine darkness, day or night.
- 9/16" Medium Cell: A .5625" honeycomb structure that improves insulation, boosts energy efficiency, and creates a clean, tailored look.
- Free Cordless Lift: Smooth, safe, and modern operation with no dangling cords, ideal for homes with children and pets.
- Sleek Vinyl Rail System: Color-coordinated headrail and bottom rail designed for long-lasting strength and a polished, cohesive appearance.
- Noise Dampening: Air trapped in the cells absorbs sound, softening street and neighborhood noise.
- White Street-Side Backing: Every color reads the same neutral white from outside, keeping your home's exterior uniform.
- Hidden Brackets: A tight inside-mount fit with no visible hardware.
Six Quiet Neutrals
Available in Winter White, White Dove, Cotton, Gray Sheen, Fawn, and Warm Cocoa. The palette is deliberately restrained, because a blackout shade spends most of its life closed, and a calm neutral reads better across a wall of windows than a strong color would.
Pro Tip: Order free samples (up to 10, shipped free) and check them against your wall color rather than your trim, since a closed blackout shade behaves visually more like a wall panel than a window.
Built for the Rooms That Need Dark
Bedrooms, nurseries, media rooms, and any window facing a streetlight or a rising sun. If you work nights, this is the specification that makes daytime sleep possible.
A realistic note: the fabric itself blocks light completely, but as with every inside-mounted shade, a little light will edge in around the window frame. For the darkest possible room, choose an outside mount with a few inches of overlap on each side and above the opening. It costs nothing extra and makes a genuine difference.
Comparing Your Options
| Shade | Light Control | Best For |

| 9/16" Day/Night | Light filtering and blackout in one shade | One window that has to do both jobs |
| 9/16" Single Cell Light Filtering | Soft diffused glow | Living areas where brightness matters |

How to Measure & Install
Taking accurate measurements is straightforward. Let us walk you through the process!
To ensure a perfect fit, keep these essential pointers in mind:
- Always use a metal measuring tape for the best accuracy; fabric tapes can stretch and lead to errors.
- If your width measurement falls on a 1/16" or 1/32" mark, round down to the nearest 1/8".
- If your height measurement lands on a 1/16" or 1/32" increment, round up to the closest 1/8".
- Always consult the Product Specifications for the product you are measuring for. If you have questions, we will be happy to help!
Instructions for Inside Mounted Cellular Shades
Depth Requirements: For an inside mount, you'll need to make sure the window frame is deep enough to accommodate the cellular shade. Refer to the Product Specifications for minimum depths depending on your chosen valance option.
Measuring the width
- The width measurement is found by measuring the inside of the window frame in three locations: the top, middle, and bottom.
- Choose the smallest of these measurements.
- If you get a 1/16" or 1/32" increment, round down to the nearest 1/8".
- That's your width for your cellular shades.
Measuring the height
- The height measurement is found by measuring the inside of the window frame in three locations: the left, center, and right.
- Choose the largest of these measurements.
- If you get a 1/16" or 1/32" increment, round up to the nearest 1/8".
- That's your height for your cellular shades.
Instructions for Outside Mounted Cellular Shades
An outside mount sits outside of the window and the window frame. Because it is meant to cover the entire space of the window, you'll need to make some additions to the measurements to make sure you order the right size. Please follow the instructions below.
Measuring the width
- Measure the width of the area you want the shade to cover across the top.
- We suggest adding at least 4 inches to the width (2 inches per side) to minimize light gaps.
- That's your width for your cellular shades.
Measuring the height
- Measure the height from where you want the headrail to sit down to the window sill or desired length.
- We suggest adding at least 4 inches to the height (2 inches top, 2 inches bottom).
- That's your height for your cellular shades.
