The Best Window Treatments for Energy Efficiency

Jul 2, 2025 | Energy Efficiency, Interior Window Treatments

Heating and cooling your home isn’t cheap, and for most homeowners, windows are one of the biggest energy drains in the house. In fact, according to the U.S. Department of Energy, up to 30% of your home’s heating and cooling energy is lost through windows. That’s a huge hit to your utility bill and your comfort.

The good news? Choosing the right window treatments can make a measurable difference. Let’s take a look at the best energy-efficient window treatments on the market today and how they can help you save money, stay comfortable, and even earn a federal tax credit.

Why Energy-Efficient Window Treatments Matter

Energy loss through windows happens in two ways:

  • Heat gain in the summer, when sunlight pours in and warms up your interior.
  • Heat loss in the winter, when warm air escapes and cold air seeps in.

By insulating your windows with the right coverings, you can reduce both issues, keeping your home cooler in the summer and warmer in the winter, all while reducing your HVAC usage.

1. Duette® Honeycomb Shades: Proven Insulation

One of the most effective energy-efficient treatments on the market is the Duette® Honeycomb Shade by Hunter Douglas. Its unique cellular design traps air in distinct pockets, creating a layer of insulation between your windows and your interior.

Honeycomb shades aren’t just smart. They’re stylish, available in a wide range of fabrics, colors, and opacities to suit any décor.

3. Roller Shades with Thermal Backing

Modern roller shades are no longer just decorative; they can be engineered with thermal or solar-reflective backings to help reduce heat transfer through windows. Light-colored or reflective fabrics can bounce sunlight back outside, keeping interiors cooler in the summer months.

They’re a great option for a sleek, minimal look while still boosting energy performance.

4. Roman Shades with Insulated Liners

Roman shades are elegant and timeless, but when paired with a thermal lining, they also provide solid insulation. The thick fabric layers help reduce heat transfer while giving rooms a soft, luxurious feel.

Custom Roman shades can also be motorized for convenience, allowing homeowners to close them during the hottest parts of the day to improve comfort and energy savings.
