Are Window Shutters Energy Efficient?

Often at Rollac, we get customers asking us, “Do shutters keep heat in? And are window shutters energy efficient?” The answer is: yes! Not only do high-quality shutters enhance your home’s style, but they also act as effective insulators, thereby helping to reduce your energy bills, remain comfortable in your surroundings year-round, and protect your interior from the elements.
How shutters work as insulators
Whether it’s wood, vinyl, or composites, creating a physical barrier between your window glass and interior is precisely the point of shutters. When they are custom-fitted, they sit snuggly within the window frame, blocking drafts and minimizing air leaks.
Their design has been created to improve your home’s R-value, a measure of thermal resistance. This means less heat escapes during winter and less heat enters during summer. Simply put, shutters help stabilize indoor temperatures by reducing the transfer of heat through your windows while minimizing the cold air that seeps through window panes.
Do Shutters Keep Heat in During Winter?
Absolutely! Yes, shutters keep heat in during colder months. Closed louvers trap warm air, minimize convective drafts occurring near the glass, and reduce nighttime heat loss.
- Material effectiveness: Wooden shutters provide unparalleled insulation, while composite shutters provide durability with strong thermal performance.
- Tangible impact: Shutters can help lower heating costs by reducing heat loss, making them a wise investment for energy-conscious homeowners.
Do Shutters Keep Heat Out in Summer?
During the warmer months, from May to September, shutters are equally as effective. Closed shutters can block solar rays, reduce glare, and keep rooms cooler by stopping sunlight from heating your interiors. In turn, this reduces the strain on your air conditioning system, improves energy efficiency, and makes those bright sunny rooms far more comfortable to use.
Energy Efficiency Compared to Other Window Treatments
When comparing shutters to blinds, curtains, or shades, shutters typically come out ahead. Thanks to their solid construction and snug fit within the window frame, they’re able to block more air leaks and provide better insulation. Shutters offer higher R-values than most soft window coverings and tend to be stronger performers year-round.
Benefits Beyond Energy Savings
Comfort: Fewer cold spots and hot zones, more consistent temperatures.
UV protection: Closed louvers help protect floors, textiles, and furniture from fading.
Curb Appeal and Value: Custom shutters are a sought-after, long-lasting upgrade that enhances both resale value and curb appeal.
