Cellular shades, summer insulation, and how to choose the right setup
Hi everyone, SmartWings team here.
As the weather gets hotter, we’ve been seeing more questions about cellular shades, especially around insulation, blackout performance, and whether motorized shades can actually help with summer comfort.
We put together a practical guide for anyone who is considering cellular shades but is not sure which type to choose.
Why cellular shades help with insulation
Cellular shades are also called honeycomb shades because the fabric is built with air pockets inside the cells.
Those air pockets create an extra layer between the window glass and the room. In summer, this helps slow down heat coming in through the window. In winter, it helps reduce heat loss through the glass.
They are not a replacement for proper home insulation or AC, but they can make a noticeable comfort difference in rooms with strong afternoon sun, large windows, or temperature swings throughout the day.
They can also help absorb some outside noise, which is one reason people often choose them for bedrooms, nurseries, home offices, and street-facing rooms.
Light filtering vs blackout
This is usually the first choice to make.
Light filtering cellular shades
These soften incoming sunlight and help reduce glare while keeping the room bright. They are a good fit for living rooms, kitchens, dining rooms, and home offices where you still want natural light during the day.
They also help with daytime privacy, although privacy can change at night when indoor lights are on.
Blackout cellular shades
These are designed to block most incoming light and create a much darker room. They are usually the better choice for bedrooms, nurseries, media rooms, shift workers, or anyone sensitive to light while sleeping.
One important note: blackout fabric does not mean zero light in every installation. A small amount of light can still come in around the edges depending on the window frame, measurement, and mounting method.
Single cell vs double cell
The cell structure affects insulation, sound absorption, and the overall look of the shade.
Single cell shades are a good everyday option for general comfort, light control, and privacy.
Double cell shades add another layer of air pockets, so they can provide better insulation and noise reduction. They are usually worth considering if the window gets direct sun, faces a busy street, or is in a room where comfort matters more.
Hazel, Nowa, and Helios: what is the difference?
Here is the simple version.
Hazel Series
Hazel uses a compact 1.50-inch / 38mm honeycomb structure and an external battery wand. This makes it a practical option for shallower window frames or for users who want easier access when charging.
Best fit: standard windows, shallower frames, simple everyday use, easier battery access.
Nowa Series
Nowa uses a wider 1.77-inch / 45mm honeycomb structure. It has a more structured look and is designed for stronger insulation and sound absorption. The battery is built into the headrail, so the whole shade looks cleaner without an external battery wand.
Best fit: bedrooms, living rooms, home offices, and rooms where both comfort and appearance matter.
Helios Series
Helios is the more design-focused option. It also uses a 1.77-inch / 45mm honeycomb structure, but the main difference is the fabric finish. The woven texture gives it a more premium interior look, so it works well in spaces where the shade needs to feel more like part of the decor.
Best fit: living rooms, kitchens, bathrooms, family rooms, and design-focused spaces.
What about unusual windows?
Cellular shades are not limited to standard rectangular windows.
For special window shapes, there are also options for skylights, trapezoid windows, and arched windows. These are useful for rooms where regular blinds or roller shades do not fit cleanly.
For skylights, the main benefit is managing overhead sunlight and heat. For trapezoid or arched windows, the goal is usually to keep the architectural shape visible while still adding light control, privacy, and insulation.
Smart control and summer automations
Motorized cellular shades are useful because they can react to your daily routine instead of waiting for you to adjust them manually.
A few common summer automations:
- Close the shades during the strongest afternoon sun
- Open them in the morning for natural light
- Close them at sunset for privacy
- Pair them with a room routine, like movie time or bedtime
- Control multiple shades together by room
Depending on the motor option you choose, SmartWings shades can work with platforms such as Apple Home, Google Home, Amazon Alexa, Samsung SmartThings, Home Assistant, Hubitat, or other smart home setups.
For battery-powered models, charging can be handled with a cable, and a solar panel can also help reduce how often you need to recharge if the window gets enough sunlight.
Cellular shades vs roller shades
Cellular shades are not automatically the right choice for every room.
If your main goal is a slim look, simple light control, or a more minimal window treatment, roller shades may still make sense.
If your main goals are insulation, softer light, blackout performance, and some noise reduction, cellular shades are usually the stronger option.
A simple way to decide:
- Choose cellular shades for insulation, bedrooms, comfort, and noise reduction
- Choose roller shades for a cleaner flat look, simpler light control, or lower visual weight
- Choose blackout cellular shades when sleep quality or screen glare is the main issue
- Choose light filtering cellular shades when you want daylight without harsh sun
Quick room-by-room suggestions
- Bedroom: blackout cellular shades, usually Nowa or Helios if you want a cleaner built-in battery look.
- Nursery: blackout cellular shades, with careful measurement to reduce edge light.
- Living room: light filtering cellular shades if you want soft daylight, blackout if the room gets harsh direct sun.
- Home office: light filtering cellular shades for glare control, or blackout if you use monitors near a sunny window.
- Street-facing windows: cellular shades can help with privacy and some outside noise.
- Skylights or angled windows: use a specialty cellular shade rather than trying to force a standard shade into the space.
Measurement matters
With cellular shades, measurement affects more than just fit. It can also affect light gaps, insulation performance, and how clean the final installation looks.
If you are trying to make a bedroom as dark as possible, pay attention to frame depth, inside mount vs outside mount, and possible side light gaps.
If your window is shallow, Hazel may be easier to fit. If you want a cleaner look with the battery hidden inside, Nowa or Helios may be the better direction.
If you are not sure which setup fits your window, feel free to leave the room type, window size, mount preference, and smart home platform in the comments. We can help you narrow it down.
