Smarter Living: Boost Your Home’s Energy Efficiency with Blinds and Curtains

When you think about making your home more energy-efficient, you likely picture insulation, double-paned windows, or energy-saving appliances. But get this: a simple revamp of your window furnishings (think: blinds and curtains) could make a difference in your energy bill and indoor comfort.

Whether to shield yourself from blaring sunlight or the uncomfortable winter chill, windows do more than any other aspect of your house to admit (and expel) heat energy.

How Blinds and Curtains Help Save Energy in Your Home

From blocking the sun to insulating against heat loss, curtains and blinds play a crucial role in the battle against energy waste. Here’s how they work and why these small additions deserve a place on your energy-saving checklist.

1. Reducing Heat Gain in Summer 

Unless you’re living in a hot climate area and summer has kicked in, your home will become the very definition of how a greenhouse should look. The proper window coverings can block this heat before it ever reaches your home.

Shiny blinds, such as those with a white or silver finish, can reflect sunlight outdoors, reducing the amount that enters your windows and keeping your house much cooler. We have thermal, or blackout, curtains designed to block heat from entering. They also block UV rays that can cause fading in furniture and floors. The result? Your air conditioning does not need to work as hard, so you will use less energy and lower your cooling costs.

2. Reducing the Loss of Heat During the Winter

As they block heat in the summer, blinds and curtains can help retain heat during colder months. Windows are one of the worst culprits for energy loss in our homes, especially if the windows are single-glazed or not insulated sufficiently. Block warm air from leaking out of your windows with thermal curtains. Blinds can be very effective at creating an air pocket between the window and the room. By keeping heat inside, these window coverings can ultimately reduce your heater use and energy costs during the winter months.

3. The Control of Natural Lighting is Improved

Energy savings isn’t just about temperature—it also concerns light. Try to use the blinds or drapes in such a way that helps natural light blend into the room if you don’t have to use the lights. You could, of course, use a screen on one side, but Venetian blinds mean you can tilt the slats to vary the shade levels and even have the sun shining directly in if you want that. When you tap into more daylight and less electric light during the day, you’re not only using less electricity but also supporting a healthy circadian rhythm, which is especially crucial if you work from home.

4. Creating Zonal Temperature Control

One of the overlooked advantages of blinds and curtains is that they can help you keep zonal temperatures in your home. That way, you can control the temperature in different rooms depending on when and how you use them. For example:

Shut the curtains of east-facing rooms in the morning to keep out intense heat. In contrast, small or shaded rooms should open their blinds during the coolest and sunniest part of the day, typically in the afternoon, to allow for passive solar heating.

This level of micro-management reduces the strain on your HVAC system and boosts your energy efficiency, all without the financial burden of upgrading to a smart home.

5. Supporting Sustainable Living

The environmentally conscious household will be pleased to know that those who convert their existing window furnishings to energy-saving window dressings are not only helping to save the planet but are also saving money.

In addition, most blinds and curtains are also eco-friendly, recyclable, or made from sustainable materials while still providing excellent performance and an eco-friendly design. When you consider the reduced energy consumption, it becomes a stylish and environmentally sustainable solution.

Selecting the Best Window Furnishings

To maximise the impact of energy savings, choose window coverings based on your climate and the direction your windows face. Reflective blinds or blackout curtains work best for high-intensity afternoon sunlight, particularly for direct south- and west-facing windows. For these windows, the maximum direct afternoon sun is received. 

South-facing windows, however, generally experience the least winter heat gain and can benefit from using thermal curtains to repel drafts. To maintain the views while filtering the light further, try sheer or layered curtains in east-facing windows that welcome intense morning light, providing a generous amount of filtered light without obstructing the views.

Another case in point? For a dual-duty solution that won’t lock you into one look all year round, you can also opt for inventive window furnishings that serve double duty throughout the seasons, such as day-and-night blinds or layered curtain duos, which provide easy options for letting light in or keeping the temperature out.
