What Are Cellular (Honeycomb) Shades?

The basic idea

Cellular shades use pleated fabric to create honeycomb-shaped air pockets that raise and lower like an accordion. Those pockets trap air next to the glass, forming an insulating barrier that helps keep indoor temperatures steadier. Among interior window coverings, insulated cellular shades are known for delivering some of the highest R-values. For Colorado Springs homes with sunny days and cool nights, extra insulation can make rooms feel more comfortable with less effort from your HVAC system.

Popular configurations

You can choose single or double cell constructions, each adding layers of trapped air. Features like top-down bottom up let in daylight from above while maintaining privacy below, a favorite in street-facing rooms. Tight-fitting sidetracks and precise inside mounts reduce gaps along the edges, which boosts energy performance. Many lines also offer cordless and motorized options for a cleaner look and easier daily use.

What Are Cellular Shades Made Of?

Common materials you’ll see

Most cellular shade fabrics are nonwoven polyester, often called spun lace, chosen for durability, uniform texture, and easy care. Many brands specify 100 percent polyester in their specs, while some incorporate blends for specific finishes. Finding eco-friendly options is easier than ever, as several product lines use recycled PET from plastic bottles. The result is a lightweight fabric that holds its crisp pleats and resists fading.

Light control and liners

Cellular shades are available in light-filtering and blackout options to meet your room’s needs. Blackout fabrics add an opaque layer that blocks light and can enhance insulation, making them useful in bedrooms and media spaces. Light-filtering fabrics soften glare without going fully dark, making them great for home offices and living rooms. Always check each model’s specifications, as construction details and liners affect both thermal performance and how the shade handles daylight.

Are Cellular Shades Energy Efficient?

The quick answer (with numbers)

When installed tightly, cellular shades can reduce heat loss through windows by 40 percent or more in winter, translating to about 10 percent savings on heating energy. In summer, snug-fitting shades can cut unwanted solar heat gain by up to 60 percent. That matters because roughly 30 percent of a home’s heating energy is lost through windows, and about 76 percent of sunlight on standard double-pane glass turns into heat. In a sunny, high-altitude market like Colorado Springs, those percentages add up fast.

What affects performance

Fit is everything. Optional side channels, careful measurements, and a tight inside mount raise the effective R-value by sealing off drafts. Cell count also matters; double-cell shades generally insulate better than single-cell designs. Add smart controls or motorization to automate opening and closing times, so you capture free winter sun and block peak summer heat without having to think about it.

Field results you can expect

Beyond lab numbers, field studies have shown cellular shades can lower heating energy use by nearly 25 percent in some real homes. The exact savings depend on your windows, climate, and how consistently you operate the shades. Homes with older or leakier windows often see the most dramatic gains. Combine shades with basic air sealing around frames, and you create a one-two punch for comfort and efficiency.

FAQ

● Q: What exactly are cellular shades?
A: Interior fabric shades that form honeycomb-like air pockets, creating top-tier insulation among window coverings.

● Q: What are cellular shades made of?
A: Typically, nonwoven polyester, often spun lace. Some products use polyester blends or recycled PET. Always confirm on the product spec sheet.

● Q: Do cellular shades really save energy?
A: Yes. Tight-fitting models can reduce winter heat loss by 40 percent or more and cut summer solar heat gain by up to 60 percent. Some homes have seen heating-energy reductions of nearly 25 percent.

● Q: Which insulates better, single or double cell?
A: Double-cell shades generally provide greater insulation because they add another layer of trapped air.
