Blackout Cellular Shades

Blackout cellular shades are designed to significantly reduce the amount of light entering your room. The blackout fabric itself provides 100% light blocking, making it an excellent choice for bedrooms, nurseries, and other spaces where a darker, more comfortable environment is preferred.

Unlike light filtering cellular shades, blackout fabrics do not allow natural light to pass through the shade. Instead, they provide stronger light control, making them particularly useful for sleeping, daytime rest, and rooms where outside light can be distracting.

While the fabric itself provides 100% light blocking, this does not mean that every installed window will be completely free of light. Small amounts of light may enter around the edges of the shade depending on the window construction, measurements, and mounting method. Proper measuring and installation can help minimize these light gaps.

Blackout and Day-to-Night Privacy

In addition to controlling natural light, blackout cellular shades provide excellent privacy at the window.

The blackout fabric is opaque, so you cannot see through it from outside during the day or at night. This makes blackout cellular window shades a great choice for bedrooms, street-facing windows, and other spaces where both privacy and stronger light control are important.

When fully lowered, the shades help reduce outside light while blocking views into the room, creating a more comfortable environment for everyday privacy, rest, and sleep.

Honeycomb Construction and Insulation

Blackout honeycomb shades use a cellular construction with air pockets inside the shade that create an additional insulating layer between the window and your room.

This cellular structure can help reduce some heat transfer through the window, combining stronger light control with an additional layer of insulation.

Actual performance can vary depending on the window, shade size, installation method, and surrounding conditions, but the honeycomb construction remains one of the defining features of cellular shades compared with simple flat window coverings.

Blackout vs. Light Filtering Cellular Shades

The main difference between blackout and light filtering cellular shades is how they manage natural light.

Blackout fabrics block light from passing through the shade, making them ideal for bedrooms, sleeping areas, and other rooms where a darker environment is preferred.

Light-filtering fabrics diffuse incoming daylight rather than blocking it, reducing harsh direct sunlight while helping the room remain bright.

If your priority is sleep, a darker room, or stronger privacy, blackout is the better choice. If you want to continue enjoying more natural daylight during the day, light filtering cellular shades may be more suitable.

Custom Sizes and Flexible Operating Options

All of our blackout cellular shades support custom sizing and can be configured according to the width and height of your window. Custom blackout cellular shades make it easier to fit windows that require precise dimensions.

Cordless blackout cellular shades eliminate traditional exposed pull cords or continuous-loop chains, keeping the window area clean while reducing exposed operating cords. For added convenience, motorized blackout cellular shades are also available.

Top down bottom up blackout cellular shades provide more flexible control at the window, allowing the shade to open from the top or adjust upward from the bottom so you can balance privacy, light control, and the amount of exposed window.

Select products are also available as no drill blackout cellular shades with no-tools installation, providing a convenient option for windows where you prefer to install shades without traditional drilling.

By combining custom sizing with your preferred color, installation method, and operating option, you can configure blackout cellular shades for different windows and rooms.
