Double Vs. Single Cell Blinds

Single and double cell blinds look the same on the surface. Each type has even rows of surface pleats that allow the blinds to fold back on themselves in compact bundles that are less obtrusive than traditional mini-blinds. The biggest difference between single and double cell blinds lies in how they're constructed.


Single cell blinds consist of two cloth sections that are folded like a paper fan. The two sections are stacked on top of each other to create single rows of channels, or cells, between the folds. Double cell blinds usually have three layers of fan-folded fabric that are stacked on top of each other in a staggered pattern that resembles the channels of a honeycomb. The channels created to form single and double cell blinds act as insulators because they trap the hot and cold air that penetrates a window. Double cell blinds are considered better insulators because they have more cells to block out air.


Cellular blinds typically consist of polyester fabric that allows light into a room while the blinds are closed, but some have a backing that blocks light just like blackout shades do. Others have cordless controls to prevent children and pets from becoming entangled in low-hanging cords. Those types of features will usually increase the costs of cellular blinds. Prices for single and double cell blinds vary widely, based on the size and type of window being covered. Expect to pay more for double cell blinds, because manufacturers generally use more fabric to make them.

Privacy and Cleaning

Some styles of single and double cell blinds can be opened by lowering them from the top or raising them from the bottom. Lowering the blinds from the top allows additional light into a room without compromising privacy, since the eye-level portion of the window remains covered. You can easily remove dust from cellular blinds by using a feather duster or a brush attachment on your vacuum cleaner.


Other window coverings may be better insulators than cellular blinds. The "Apartment Therapy" website notes that cellular blinds and curtains can be pricey, but layered curtains made of heavy fabrics might do a better job of blocking out drafts. However, curtains don't let as much light into a room as cellular blinds do. That may not be a problem if you have several windows in a room that would prevent curtains from darkening the space more than you want.
