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.
