Let's Settle It: Are Single Cell or Double Cell Blinds Better?

I remember standing in my first 'fixer-upper' kitchen at 11 PM, trying to ignore the draft whistling through the original 1920s casing while I stared at a pile of fabric swatches. I wanted that clean, architectural look, but I also didn't want my coffee to freeze before I could drink it the next morning. The question that kept me up was simple: are single cell or double cell blinds better?

It is easy to get paralyzed by the technical specs when you are looking at a cross-section of a honeycomb shade. They all look like accordion paper until you actually hang them and realize one looks like a crisp designer choice and the other looks like a heavy-duty industrial insulator. There is a sweet spot for both, but choosing wrong usually means either a window that still feels like an icebox or a shade that sticks out three inches past your trim.

• Choose single cell for a modern, large-pleat look (usually 3/4 inch or 9/16 inch) and shallow window frames.
• Choose double cell for maximum R-value insulation in bedrooms or sunrooms.
• Double cells have smaller, busier pleats that can look a bit 'fussy' in large windows.
• Single cells are generally more affordable and easier to install in tight spaces.

The Great Honeycomb Debate (And Why It Actually Matters)

When clients ask me what is the difference between single and double cell shades, I tell them to look at the side profile. A single cell is one row of hexagonal 'cells' that trap air. A double cell is essentially two layers of honeycombs stacked or nested together. It creates a secondary airlock.

The anatomy matters because of your window depth. If you have those beautiful, shallow windows found in older bungalows, a double cell shade might not even fit inside the mount. You will end up with a bulky bracket sticking out, which is a total design crime in my book. It is about balancing the thermal physics with the actual physical space you have to work with.

When the Single Cell Wins (Crisp Lines and Shallow Windows)

I find that single cell versus double cell cellular shades often comes down to the 'vibe' of the room. Single cell shades usually come with larger pleat sizes—think 3/4 inch or even larger. These wider folds look more like a custom Roman shade and less like a piece of office equipment. They feel architectural and high-end.

If you are outfitting a whole floor with cellular shades, the single cell is my go-to for the living areas. They are lighter, which means the cordless mechanisms tend to last longer because they aren't fighting against the weight of extra fabric layers. Plus, if your window casing is less than 2 inches deep, a single cell is often your only choice for a clean, flush inside mount.

The Heavy Lifter: Why I Specify Double Cell for Drafts

Functionally, if you are asking which is better single or double cell shades for a bedroom that faces north in a Minnesota winter, the answer is double cell every single time. The R-value—which measures thermal resistance—is significantly higher. It creates a literal wall of dead air that keeps the heat in and the 'scary-cold' out.

I’ll admit it: for a long time, I thought double cell cellular shades were too bulky for my tastes. I hated the way the smaller pleats looked cluttered. But after living with a set in a drafty guest room, I changed my tune. You just have to be intentional about the color; a soft white or cream helps hide the 'busy' lines of the double honeycomb. If you are worried about the aesthetic, it really comes down to which pleat size looks custom in your specific window—smaller windows actually handle the double-cell scale quite well.

A Quick Word on Triple Cell (Yes, They Exist)

You might see triple cell options popping up in some catalogs. Honestly? In most homes, they are overkill. Comparing double cell vs triple cell shades is like comparing a heavy winter coat to a polar expedition suit. Unless you are living in extreme sub-zero climates or have a room that is essentially all glass with zero insulation, triple cells are too heavy, too thick, and frankly, they look a bit like a padded cell. Stick to double cell for your heavy-duty needs.

Brand Breakdown: Spotting the Differences in Store

When you look at levolor single vs double cell options, pay attention to the fabric stiffness. Some brands use a softer, more fabric-like material for their single cells, while the double cells might feel more 'papery' to maintain that complex structure. The light-filtering properties also change; a double cell will naturally block more light because there are more layers of material for the sun to fight through.

Always ask for a sample. Hold it up to your actual window at 4 PM. You might find that a double or single cell shades choice is made for you once you see how the light hits the pleats. A single cell lets in a beautiful, diffused glow, whereas a double cell can sometimes feel a bit 'flatter' when backlit.

The Final Verdict on Your Windows

So, which is better single or double cell shades? If you want a modern look with wide pleats and your windows are relatively modern and energy-efficient, go with the single cell. If you are tired of wearing a sweater to bed because your windows are drafty, the double cell is worth every penny of the upgrade. For those tricky spots like motorized skylight cellular shades, I almost always lean toward the highest insulation possible since heat rises and escapes right through that ceiling glass.

My Honest Mistake

I once ordered double-cell shades for a sunroom with very narrow 1.5-inch casings. I didn't check the mounting requirements. When they arrived, they stuck out so far from the wall that I couldn't even install the decorative trim I had planned. I had to eat the cost and re-order single cells. Measure your depth twice, then measure it again. Your ego (and your wallet) will thank you.

FAQ

Is double cell worth the extra money?

Yes, if you live in a climate with extreme temperatures. The energy savings on your AC and heating bills usually offset the higher price tag within a few seasons.

Do double cell shades block more light?

Slightly. While they aren't 'blackout' unless specified, the extra layer of fabric and the nested air pockets naturally diffuse more sunlight than a single layer.

Which is easier to clean?

Single cell. You can easily run a vacuum brush attachment down the larger pleats. Double cells have more nooks and crannies where dust and the occasional brave spider like to hide.
