Best Window Coverings for Energy Efficiency
The right window coverings can significantly reduce your heating and cooling costs. Here are the most energy-efficient options.
Why Do Window Coverings Matter for Energy Efficiency?
Windows are responsible for 25–30% of residential heating and cooling energy use. In Canadian climates with harsh winters, poorly insulated windows let heat escape constantly.
The right window coverings create an insulating barrier that reduces this energy loss, keeping your home warmer in winter and cooler in summer — while lowering your utility bills.
Which Window Coverings Are Most Energy Efficient?
1. Cellular Shades (Honeycomb Shades) — The most energy-efficient window covering. Their honeycomb air pockets create an insulating layer that can reduce heat loss by up to 40%. Double-cell options like Duette provide the highest performance.
2. Shutters — Wood and composite shutters provide solid insulation when closed, and their tight fit against the window frame minimizes air leakage.
3. Roman Shades — Thick fabric Roman shades with blackout lining add insulation, especially when closed.
4. Layered Treatments — Combining shades with draperies creates multiple barriers against heat transfer.
5. Motorized Shades with Scheduling — Automated shades that open and close based on the sun's position optimize passive solar heating.
