What is the best insulating window treatment?
If you’re looking for the best window treatment for insulation, especially to save on energy bills and keep rooms comfy year-round, here are your top options:
🥇 1. Cellular Shades (Honeycomb Shades) – Best Overall for Insulation
-
Why they win: Their unique honeycomb structure traps air in pockets, creating a thermal barrier.
-
Options: Single-cell, double-cell, or even triple-cell for max insulation.
-
Extras: Available as top-down/bottom-up and blackout for light + privacy control.
-
Ideal for: Bedrooms, living rooms, anywhere you want to keep cool or warm.
🏆 2. Layered Curtains (Thermal or Blackout Drapes)
-
Why they work: Heavy fabric blocks cold drafts and heat loss through glass.
-
Insulation boost: Combine with a cellular shade underneath for double the insulation.
-
Style perk: Adds softness and texture to a room.
-
Tip: Make sure they’re floor-length and wide enough to overlap the window frame.
🪟 3. Shutters (Especially Plantation Shutters)
-
Why they help: Solid materials (wood or faux wood) act like a built-in barrier.
-
Tight fit = less air leakage.
-
Bonus: Great curb appeal and increase home value.
-
Downside: Pricier than shades or curtains.
🧵 4. Roman Shades (With Thermal Lining)
-
Good insulation if made with heavier fabrics and backed with a thermal liner.
-
Stylish and customizable.
-
Less insulating than honeycomb shades, but better than standard blinds.
🪞 5. Roller Shades with Thermal Backing
-
Sleek, modern, and can come with energy-efficient coatings.
-
Not as insulating as cellular, but good for small or minimalist spaces.
🔧 Bonus Tip: Combine Treatments
You can layer treatments for better results:
Cellular shade + thermal curtain = elite insulation + style + light control.
