Cellular shades, also called honeycomb shades, are pleated fabric window coverings with air-trapping cells that insulate windows while controlling light and privacy.
Cellular shades get their name from the honeycomb-like hexagonal structure built into the fabric. Those hollow cells trap air between the window and the room, which is what makes this style stand out from flat roller or Roman shades. Manufacturers such as Hunter Douglas, Kirsch, and Lutron all build their own versions of this design, and the terms “cellular” and “honeycomb” are used interchangeably across the industry.
If you’re comparing window coverings, this guide covers how cellular shades work, the main configurations available, and what to watch for on child safety. When you’re ready to see specific models side by side, our roundup of the best custom cellular shades walks through today’s top picks.
How Cellular Shades Insulate A Window
The fabric cells are the whole story. Each shade is built from accordion-style pleats that form open tubes when the shade is extended. Single-cell shades have one layer of these tubes; double-cell shades stack two layers for a thicker air gap and a higher insulation value.
That trapped air slows heat transfer in both directions. In summer, less outdoor heat radiates through the glass into the room. In winter, the air pocket keeps room warmth from escaping toward the cold pane. The insulation effect is modest compared to storm windows, but it is real and measurable.
Main Configurations: Cordless, Motorized, And Top-Down
Cellular shades are not one single product. Major lines such as Hunter Douglas’s Duette® Honeycomb Shades and Sonnette® Cellular Roller Shades come in several operating styles, and Kirsch offers its own cellular line with similar choices.
- Cordless shades lift and lower by pushing up on the bottom rail or pulling a small tab. With no hanging cords, they are the most common recommendation for homes with children or pets.
- Motorized shades run on a rechargeable battery or hardwired power and operate from a remote, a wall switch, or an app. Hunter Douglas calls its automation system PowerView®. These suit hard-to-reach windows such as ones above a staircase or behind furniture.
- Tie-down and loop options: some cellular shades use a standard cord (roughly 1.2 mm in diameter) or a continuous cord loop (about 4 mm in diameter). Continuous loops are generally used for larger window openings over 60 inches wide, especially with heavier blackout fabric.
- Top-down/bottom-up shades lower from the top as well as rise from the bottom. You can drop the top of the shade a few inches to let daylight in while the lower half stays closed for privacy.
Cellular vs. Honeycomb: What’s The Difference?
There is no difference. Cellular and honeycomb are two names for the same window covering, and manufacturers use both terms in their product descriptions. Lutron simply calls its versions cellular shades. If you see one product labeled “honeycomb” and another labeled “cellular,” you are looking at the same basic construction, not two competing technologies.
Child Safety And Cord Rules
Window cords are a documented strangulation hazard, and the industry has been pushing cordless and motorized designs for years. Retailers still sell continuous-cord and top-down/bottom-up variants that comply with the child-safe rules, but the older free-hanging cord design is gone from new stock.
If you have older corded shades already installed, secure the cords with a cleat, a tension device, or a breakaway connector, and keep every loop out of a child’s reach. For a nursery or a family room, cordless or motorized is the safer choice and removes the concern entirely. Never assume a shade is cordless because it looks clean from a distance — check the operating mechanism before you buy.
| Configuration | How It Operates | Best For |
|---|---|---|
| Cordless | Push bottom rail or tab to move | Homes with kids or pets |
| Motorized | Remote, switch, or app control | Hard-to-reach windows |
| Top-down/bottom-up | Opens from top or bottom | Daylight plus privacy |
| Continuous cord loop | Loop cord, typically 4 mm | Wide windows over 60 inches |
Cellular shades also filter light by fabric density. Light-filtering fabrics soften daylight while keeping the view partially visible; blackout fabrics block light almost entirely for bedrooms or media rooms. Both fabric types are available in cordless and motorized configurations, so the safety choice does not force you to give up light control.
One more thing worth knowing: all-color claims aside, white and light neutral fabrics reflect more heat than dark colors, so the fabric choice affects energy performance as much as the cell structure does.
FAQs
Do cellular shades actually save energy?
Cellular shades reduce heat transfer through the window by trapping air in the fabric cells, so they take some load off your heating and cooling. The effect is real but modest. Single-cell shades give a light insulation boost, while double-cell versions add more, and pairing them with a tight window seal improves results.
Are cordless cellular shades worth the higher price?
Cordless shades cost more than basic corded ones, but they remove the strangulation hazard entirely and work well in any room. For homes with young children or pets, the added cost buys real safety. Motorized versions cost most of all but earn their keep on tall or hard-to-reach windows.
Can you add a motor to an existing cellular shade?
Retrofitting a motor to an existing corded shade is generally not practical, since the lift mechanism differs. Most manufacturers sell motorized shades as a complete unit. If automation matters to you, order the motorized version from the start rather than hoping to convert a manual shade later.
