Why Do Honeycomb Shades Come In Different Cell Sizes?

Each Honeycomb Shade is made up of a series of pleats that look remarkably like - you guessed it - honeycombs. But why? What do these cells do? And why do Honeycomb Shades come in a wide variety of cell sizes?


If you’ve ever seen Honeycomb Shades, it’s pretty obvious how these window treatments got their name. Each shade is made up of a series of pleats that look remarkably like – you guessed it – honeycombs. But why? What do these cells do? And why do Honeycomb Shades come in a wide variety of cell sizes?

Now Available! 2″ Grand Cell

Just when you thought you knew everything there was to know about Honeycomb Shades, we go and change the game. Our new 2” Grand Cell Honeycomb Shades, with fewer horizontal lines running through them, are ideal for extra tall and extra wide windows. They also are suitable for vertical applications, making them an excellent alternative to Vertical Blinds or Curtains for sliding glass doors.

Honeycomb Cell Size Matters

Those who have visited our blog before know we love to tout the energy efficient qualities of our Honeycomb Shades. It’s just one of the many reasons why these window treatments remain a customer favorite. And the secret to that energy efficiency is – you guessed it again – the honeycombs!

Each honeycomb, or cell, creates an insulating pocket of inert air. Now why is this so important? Well, if you remember back to high school science class, you may remember that inert air is a poor conductor of heat. So, the more cells there are, and the bigger the cells, the more energy efficient the shade.

Honeycomb Shades can help reduce heat transfer through a window by as much as 55 to 65 percent, which is a BIG deal. This is because when it comes to energy efficiency and heat loss, windows are some of the most vulnerable areas of our home. In fact, the U.S. Department of Energy (DOE) claims that windows account for 25-40% of a home’s annual heating and cooling costs. This is because heat always travels from warm areas to cool areas along the path of least resistance – in this case that means your windows.

“Windows lose more heat per square foot of area in winter and gain more heat in summer than any other surface in the home,” according to the Penn State College of Earth and Mineral Sciences.

The best way for homeowners, like you, to reduce this heat transfer is by investing in the right window treatments, which will help increase the R-Value (insulating power) of your windows. The average window has an R-Value of just 1.16, according to the University of Alaska Fairbanks. For comparison, the average exterior wall has an R-Value of 13.1. So, it’s no wonder your windows are so vulnerable. The good news: Honeycomb Shades can increase a window’s R-Value anywhere from 3.45 and 5.00. While this may not sound like much, it can actually make a big difference.

Honeycomb Shades from Next Day Blinds

Our Honeycomb Shades help regulate your home’s temperature and prevent unwanted energy loss. These window treatments are available in a large variety of colors, textures, and, best of all, cell sizes.

Cell Sizes

Small cell sizes, like our 3/8″ Single Cell, are perfect for small or narrow windows. The narrows cells may look too busy if placed in larger windows. These smaller cells are also ideal for windows with narrow sills.

Medium cell sizes, like our 1/2″ Double Cell, are a versatile choice, great choice for all window sizes without looking chaotic. The medium cells look great in small and large windows alike.

Large cell sizes, like our 3/4″ Single Cell and our new 2″ Grand Cell, are ideal for large or deep windows. The larger cell size helps provide visual balance and symmetry.

Double Cell vs. Single Cell

Double Cell Honeycomb Shades are the ideal choice for maximizing energy efficiency. The double cell design features two insulating pockets per pleat, offering more insulation than the single cell shade.

Single Cell Honeycomb Shades are the more cost-conscious choice compared to double cell. And while they provide less insulation than double cells, they are still an excellent energy efficient option.
