EnergySave Cellular Shades

Windows are the largest source of heat loss in winter and heat gain in summer—accounting for up to 50% of a home's energy bill. EnergySave Cellular Shades are engineered to dramatically reduce this energy waste, paying for themselves through lower utility costs. The secret is the honeycomb cell structure: each hexagonal cell traps still air, creating a thermal barrier between the window glass and your room. The deeper the cell and the more layers, the greater the insulation. Our top-of-the-line 1⅛-inch double-cell shades achieve an R-value of 5.2—comparable to a low-E storm window. Add our optional perimeter sealing system, and you can reduce air infiltration by up to 85%. Available in all cell sizes and opacities, with cordless, continuous cord loop, or motorized operation. Custom‑sized to your exact window dimensions. Save energy, save money, stay comfortable.

R‑Value Comparison

Shade Type R‑Value Heat Transfer Reduction
¾" Single Cell 1.8 25%
1⅛" Single Cell 2.5 35%
1⅛" Double Cell 3.5 45%
1⅛" Double Cell + Side Seals 4.2 55%
1⅛" Double Cell + Full Perimeter Seal 5.2 65%

R‑values are measured at the center of the shade; actual performance varies by window type, climate, and installation quality.

How Cellular Shades Save Energy

  • Winter — Trapped air cells prevent convective heat loss, creating a still‑air buffer between cold glass and your warm interior.

  • Summer — The same air cells resist conducted heat gain. Light‑colored fabrics also reflect solar radiation before it enters the room.

  • Year‑round — Reduced HVAC load lowers energy bills and extends equipment life.

Energy Savings Calculator

Our website features an interactive energy‑savings calculator that estimates your annual savings based on window size, climate zone, energy costs, and shade selection. Typical payback periods range from 3 to 7 years—after that, the savings are pure return.

ENERGY STAR® Qualified

Select EnergySave cellular shades meet the stringent criteria for ENERGY STAR® certification in the Window Coverings category. Look for the ENERGY STAR mark on qualifying models. These shades may also be eligible for utility rebates or tax incentives; check your local programs for details.

Draft Blocking Upgrade

For maximum efficiency, add the ThermoSeal perimeter sealing system. Side channels, a magnetic bottom seal, and a top seal work together to eliminate air infiltration around the shade edges. This upgrade is especially effective on older, draft‑prone windows.

Ideal for All Climates

  • Cold Climates — Double‑cell shades with side seals maximize heat retention.

  • Hot Climates — Light‑colored single‑cell shades reflect solar gain while allowing ventilation.

  • Mixed Climates — 1⅛" single‑cell shades offer balanced, year‑round performance.
