Best Cellular Shades for Energy Efficiency (2026): Honeycomb Picks
Cellular shades trap air in honeycomb cells, cutting heat gain through windows by up to 40%. The premium energy-efficient window treatment for California west-facing rooms.
Cellular shades, also called honeycomb shades, are the most energy-efficient soft window treatment. The honeycomb structure traps a layer of insulating air between the room and the glass. For California west-facing rooms baking in afternoon sun, they cut heat gain dramatically.

Our Picks
Single Cell vs Double Cell
Single cell: one row of honeycomb cells. R-value 2.0-2.5. Adequate for most rooms.
Double cell: two rows of cells, double the air trap. R-value 3.0-4.0. Best for west-facing rooms or anywhere energy efficiency matters most.
Triple cell exists but the marginal gain over double cell isn't worth the cost.
Top-Down Bottom-Up Feature
The killer cellular-shade feature: top-down/bottom-up operation. Lower the top of the shade for privacy from people walking by, while letting in light from above. Or raise the bottom for full view. Bedrooms and bathrooms benefit most. Privacy + light without compromise.
Cordless and Motorized Options
Cordless cellular shades are now the standard (kid-safe, no dangling cords). Pull-down works smoothly with the right tension setting.
Motorized cellular shades pair with smart-home systems. Lutron Serena is the premium brand; Levolor and Bali both make competent battery-powered motorized options.
