The most energy-efficient window treatment you can buy. Cellular shades trap air in honeycomb pockets to insulate your home year-round — cutting energy bills by up to 25%
Direct Answer
Cellular shades (also called honeycomb shades) feature a distinctive honeycomb cross-section that traps air between your window and room, creating an insulating barrier. This design can reduce heat loss by up to 40% in winter and block solar heat gain in summer, making them the single most energy-efficient window treatment available.
Expanded Detail
The cellular design works by creating one or more air pockets between layers of fabric. These pockets act like insulation, similar to how double-pane windows work. In winter, they prevent warm interior air from escaping through the glass. In summer, they block radiant heat from entering. The U.S. Department of Energy has confirmed that cellular shades can reduce heat loss through windows by up to 40%, which translates to energy bill savings of up to 25% depending on your climate, window exposure, and existing insulation. Available in single-cell and double-cell configurations, with options ranging from sheer to complete blackout.
Direct Answer:
Yes. Cellular shades can reduce energy bills by up to 25% by creating an insulating air barrier between your window and room.
Expanded Detail:
The honeycomb cells trap air, which is one of the best insulators available. (Fun fact! They were originally intended for insulation.) The U.S. Department of Energy has confirmed that cellular shades reduce window heat loss by up to 40%. Double-cell configurations provide even greater insulation than single-cell. The exact savings depend on your climate zone, window orientation, and existing insulation, but most homeowners see measurable reductions in heating and cooling costs within the first season.
Direct Answer:
Double cell shades have two layers of honeycomb cells for up to 40% more insulation than single cell. Single cell shades offer a sleeker, more compact profile.
Expanded Detail:
Single cell shades have one layer of air pockets and provide good insulation (R-2 to R-3). Double cell shades nest a smaller cell inside a larger one, creating two insulating air layers (R-3 to R-5). If you live in an extreme climate — very cold winters or very hot summers — double cell is worth the upgrade. For moderate climates, single cell provides excellent performance with a slimmer stack and slightly lower cost.
Direct Answer:
Yes. Cellular shades are available in blackout opacity, which blocks 99%+ of light for complete room darkening.
Expanded Detail:
Room Darkening cellular shades use opaque fabric and a light-trapping cell design that eliminates virtually all light penetration. They are the most popular choice for bedrooms, nurseries, home theaters, and shift workers who sleep during the day. For maximum light blocking, pair room darkening cellular shades with a valance or side channels to eliminate light leakage around the edges.
Direct Answer:
Yes. Top-down/bottom-up is the most popular operating system for cellular shades, available on all configurations.
Expanded Detail:
Top-down/bottom-up (TDBU) allows you to lower the shade from the top, raise it from the bottom, or position it anywhere in between. This is ideal for rooms where you want natural light from above while maintaining privacy at eye level — like bathrooms, bedrooms, and street-facing windows. TDBU is available on single cell, double cell, and all opacity levels from sheer to blackout. It can also be motorized for hands-free control.

Most repairs can be completed on-site in a single visit, saving you the cost and hassle of full replacement. We carry common replacement parts on our service vehicles for faster turnaround.
Direct Answer:
A Day/Night cellular shade combines two fabrics — one light filtering, one room darkening — in a single shade on one headrail. You control each layer independently, giving you soft, diffused light during the day and complete darkness at night without installing two separate window treatments.
Expanded Detail:
Day/Night shades are the most functional single-shade solution for bedrooms and nurseries where light needs change completely between day and night. During the day, position the light filtering layer to fill the room with soft, diffused light. At night, switch to the room darkening layer for complete darkness. Both layers operate on the same system — no second shade, no extra hardware, no complicated installation. Day/Night cellular shades are available in standard and custom sizes and can be motorized for one-touch switching between layers.
