Shutters or blinds – which are more energy efficient?


Your choice of window coverings can play a key role in making your home more energy efficient. Research indicates that up to 30% of total heat loss from your home1 occurs through uncovered windows. The right covering can provide an effective thermal layer, naturally keeping your rooms cooler in summer and warmer in the winter—reducing the need to use electricity or other methods to control your home. 

So, which is the best option for energy efficiency? Are shutters or blinds more effective? The simple answer is that it all depends on the nature of the room, how you use it, and the degree to which you want light and air to flow into the space. Here’s a quick overview of the features and benefits of each option:

Achieving sophistication and energy efficiency with shutters

Shutters are a great way to control the amount of natural light and air that flows into your home. As they are completely adjustable— and can be configured in a way that’s right for each window in your home—they allow you to fully control the solar energy entering your windows and doors. 

Luxaflex® PolySatin® Plantation Shutters are a particularly ideal choice when it comes to energy efficiency. Their cellular construction creates a layer of energy-saving insulation as it traps air within a distinct pocket. Coupled with polyresin's low conductivity, they greatly reduce heat exchange. PolySatin® Shutters reflect inbound solar rays back to the outside during summer, but can be opened to allow the warming sun into your home in winter thereby reducing air-conditioning costs. These shutters can also reduce heat flux by 20-58%2 depending on the degree of air exchange between the window and the shutter panel, saving on your cooling costs.

As well as helping you maintain your interior temperature, shutters can also play an important role in helping you protect your furnishings and fittings from the sun’s harmful rays. By breaking up light as it enters your home, this can assist with keeping your furnishings from fading over time. 

Ensuring smart thermal control with shades

We offer a wide range of Luxaflex® SoftShades, all of which provide a degree of thermal control for your interiors: 

Luxaflex® Duette® Shades are one of the most energy efficient and durable window coverings on the market, and have been specially designed for thermal control. They have a unique honeycomb 'cell' structure which traps air and acts as an insulation barrier for windows. 

The Luxaflex® Duette® Architella® range takes this a step further—with a unique honeycomb-within-a-honeycomb cell construction which creates four fabric layers and three insulating pockets of air. These smart air pockets can reduce your home's heating costs by up to 43%3.

Luxaflex® Silhouette® Shadings offer a more subtle way to control the flow of light. Their signature S-Vanes can help you transform harsh sunlight into gentle, diffused glow. While they offer less thermal control than Duette Shades, these are also made to filter harsh UV rays to protect your furnishings from damage.
