The Most Energy-Efficient Window Coverings To Keep Your Home Warm and Bills Low

When it comes to energy efficiency, your windows play a vital role. They’re often the weakest link in maintaining a comfortable indoor temperature. That’s where energy-efficient window coverings come in. By choosing the right dressings, you can reduce heat loss, keep out the cold, and cut down on energy bills—while improving the look of your room.

Here we look at the most energy-efficient window coverings available in the UK.

Plantation Shutters

Plantation shutters are not just a stylish choice; they’re also the number one choice for excellent insulation. Made from wood, faux wood, or PVC, shutters create a barrier against drafts while allowing you to control light and airflow.

Benefits:

• Effective at reducing heat loss by up to 62%.
• Durable and long-lasting.
• Easy to clean and maintain.

Best for: Homes where privacy is important or rooms where airflow needs to be adjustable.

Custom-fitted plantation shutters are most effective, as they seal tightly against the window frame, keeping warm air in and cold air out.

Cellular Shades (Honeycomb Blinds)

Cellular shades, also known as honeycomb blinds, are an effective option for improving energy efficiency. Their unique honeycomb structure traps air in pockets, creating a layer of insulation between your window and the room.

Benefits:

• Reduce heat loss by up to 40%.
• Block incoming heat in summer, keeping your home cool.
• Available in a range of colours and light-filtering options.

Best for: Homes or rooms with large windows.

For even better insulation, choose double or triple-cellular designs. These add extra layers of air pockets, improving their efficiency.

Thermal Curtains

Thermal curtains are heavy, insulated curtains designed specifically to block out cold drafts in winter and excessive heat in summer. They typically feature multiple layers, including thick fabric and foam or reflective backing.

Benefits:

• Prevent up to 25% of heat loss in winter.
• Provide excellent light and noise blocking.
• Available in various styles and lengths to suit any decor.

Best for: Bedrooms, living rooms, or any space where you want maximum warmth and privacy.

For best results, get curtains that extend beyond the edges of the window and hang them as close to the window as possible.

Roman Shades

Roman shades are an economical and practical option. When lined with thermal or blackout fabric, they provide insulation and light control.

Benefits:

• Versatile design complements traditional and modern interiors.
• Customisable with insulating linings for added energy efficiency.
• Easy to operate.

Best for: Smaller windows or rooms where aesthetics and functionality need to balance.

Opt for shades with a thermal lining to make the most of their energy-saving potential.

Solar Shades

Solar shades are designed to block UV rays and reduce heat gain, making them a popular choice for south-facing windows or areas with lots of sunlight.

Benefits:

• Reduce glare while maintaining outdoor views.
• Block harmful UV rays.
• Help keep rooms cool in summer.

Best for: Conservatories, home offices, or any space where natural light is essential.

Look for shades with a lower openness factor (1%-5%) for better energy efficiency.

Window Films

While not technically a window covering, window films are a cost-effective and energy-efficient option. These thin, adhesive films can be applied directly to your windows to block heat, UV rays, and glare.

Benefits:

• Affordable and easy to install.
• Reduces heat gain in summer.
• Preserve views and natural light.

Best for: Renters or those looking for a temporary energy-saving solution.

Combination Options

For maximum efficiency, consider combining different types of window coverings. For example:

• Combine thermal curtains with cellular shades for layered insulation.
• Add plantation shutters beneath solar shades for year-round energy control.

The layered approach provides flexibility, allowing you to adapt your window coverings to the changing seasons.

How Window Coverings Save Energy

Windows account for up to 30% of a home’s energy loss. Energy-efficient window coverings work by:

Reducing Heat Loss: Insulated coverings trap warm air inside during winter.

Minimising Heat Gain: Reflective surfaces and UV-blocking fabrics keep out unwanted heat in summer.

Improving Temperature Control: Adjustable coverings let you precisely manage sunlight and airflow.

By improving your home’s insulation, you’ll rely less on heating and cooling systems, saving energy and lowering your bills.

Choosing the Right Option

When selecting energy-efficient window coverings, consider the following:

• Climate: In colder areas, focus on insulation. In warmer climates, prioritise heat blocking.
• Room Function: Bedrooms may require a solid design, while living rooms benefit from light-filtering coverings.
• Style: Choose options that match your home’s decor.

Energy-efficient window coverings are a simple yet effective way to make your home more comfortable and sustainable.

Invest in the right window coverings today and enjoy a home that stays warm in winter, cool in summer, and kinder to your wallet year-round.
