What Are Honeycomb Shades? (And Do They Belong in a Designer Home?)

I remember my first winter in a drafty 1920s brownstone. The windows were original, which meant they were beautiful, but they leaked heat like a sieve. My morning coffee would go cold in five minutes flat. I tried heavy velvet curtains, but they felt suffocating in a narrow living room. That was the year I finally caved and started researching what are honeycomb shades to see if they could actually save my utility bill without ruining my aesthetic.

• They are the most energy-efficient window treatment on the market.
• Honeycomb and cellular shades are the exact same thing.
• They come in single or double-cell layers for varying levels of insulation.
• To make them look high-end, you must layer them with drapery.

The Big Question: What Are Honeycomb Shades, Exactly?

From the front, these look like a standard pleated blind with clean, horizontal lines. But if you turn your head and look at the side profile, you'll see a series of hexagonal pockets that look exactly like a bee's honeycomb. This is where the name comes from.

When you ask what is a cellular shade, you are looking at the same structural engineering. Instead of a single flat piece of fabric, two or more layers are bonded together to create these air-trapping channels. When the shade is lowered, these pockets expand; when raised, they stack into a surprisingly tiny, low-profile footprint at the top of your window frame.

Wait, What Are Cellular Blinds Then? (Decoding the Jargon)

If you have been scouring the internet and feeling confused by search results for what are cellular blinds versus honeycomb shades, I have good news: you can stop overthinking it. They are the same product. The industry uses the terms interchangeably, though 'cellular' tends to be the technical term used by architects and 'honeycomb' is the friendlier retail name.

Whether you see a listing for what is cellular blinds or honeycomb treatments, you are looking at the same pleated fabric tech. You can start browsing the different textures and light-filtering levels in our Cellular Shades collection to see how the fabric quality varies between brands.

The Secret Superpower: How Those Little Pockets Trap Air

The magic isn't in the fabric itself, but in the air trapped inside those cells. Air is a poor conductor of heat. By creating a stagnant pocket of air between your room and the glass, you are essentially adding a layer of insulation to your window. In the summer, it keeps the 4 PM baking sun from turning your bedroom into a sauna; in the winter, it stops the glass from sucking the heat out of your house.

This drastically improves your home's R-value, which is just a fancy way of saying how well a material resists heat flow.

Single Cell vs. Double Cell: Which Do You Actually Need?

I usually steer my clients toward a 3/4-inch single cell for most standard windows. It’s the Goldilocks size—not too chunky, not too dainty. It fits perfectly in a standard 2-inch window casing without protruding past the trim. If you live in a climate with extreme temperatures (looking at you, Minnesota), double cells are the way to go. They stack two rows of pockets for maximum thermal resistance.

Just be careful with the pleat scale. A tiny 3/8-inch pleat can look a bit busy on a large picture window. On the flip side, a large pleat on a tiny bathroom window looks like a mistake. Match the scale of the 'honeycomb' to the scale of the glass.

Do They Belong in a High-End Room? (My Honest Styling Advice)

Here is my designer hot take: cellular shades are a functional necessity, not a decorative focal point. If you hang a white polyester honeycomb shade alone on a window, it looks like a doctor’s office. To make it work in a high-end room, you have to layer. I love using a blackout cellular shade mounted inside the frame, then hanging 96-inch linen drapes with 2.5x fullness on a matte black rod outside the frame.

They are also the absolute best solution for architectural headaches. For instance, the Canisteo Motorized Skylight Cellular Shades Flex is a lifesaver for those hard-to-reach ceiling windows. It tames the glare on your TV or art collection without requiring a 20-foot ladder every time the sun moves.

The Final Verdict: When to Splurge and When to Skip

I always splurge on honeycomb shades for nurseries and media rooms. The side-channel options provide the best light blockage of any treatment I’ve ever installed. I once installed a set in a south-facing nursery where the sun was relentless, and it finally allowed the baby (and the parents) to sleep past 6 AM.

However, I skip them in formal dining rooms where I want the organic texture of a woven wood or the soft folds of a Roman shade. Honeycombs are the workhorses of the window world—use them where you need performance, then dress them up with fabric to give the room soul.

FAQ

Are honeycomb shades hard to clean?

Not really. I just use the brush attachment on my vacuum once a month. If a bug gets stuck inside a cell (it happens), a quick blast from a hair dryer on the cool setting usually blows it right out the other side.

Do they provide privacy at night?

Yes. Even the light-filtering versions will obscure shapes and movement from the outside. If you want total 'shadow-proof' privacy, go with a blackout fabric option.

Can they be motorized?

Absolutely, and I highly recommend it. Cordless is safer and looks cleaner, but motorization is what makes these feel like a luxury upgrade rather than a basic hardware store fix.
