Best Summer Curtains: Fabrics, Fit, and What Really Keeps Rooms Cool
By Ana Zuravliova
Summer is synonymous with sunshine, long days, and vibrant energy, but it also brings intense heat and a blazing sun that can turn your home into a sauna. But beyond temperature control, summer is really about transforming your home into a brighter, lighter, more uplifting space that reflects the season. The right curtains can make a world of difference, not just in terms of aesthetics but also in shaping the way your rooms feel during long, sun-filled days. Here’s a guide to the best summer curtains that blend style, function, and seasonal interior design appeal.
Why summer curtains?
Curtains are a fantastic way to add a stylish edge to home. Whether you’re looking for summer curtains for living rooms, bedrooms or dining rooms, there are some considerations to take into account to ensure you find the perfect window furnishings for the warmer months. Most people start by choosing fabric and colour when shopping for summer curtains — but that’s only the first step. What often has a bigger impact is everything that comes after. Factors like how well the curtains cover the window, how far the pole extends beyond the frame, how much airflow is allowed to circulate, and when the curtains are opened or closed throughout the day all play a crucial role.
In other words, installation and usage often matter more than the material itself. Keep this in mind as you explore fabric options below as even the best curtains won’t perform well if they’re not set up properly.
Light and breezy linen curtains
Beyond blackout and thermal curtains, there are several styles that are ideal choices for the warmer months. Linen curtains, for instance, are a summer favourite due to their light, airy texture and natural look.
These beautiful curtains allow just the right amount of sunlight to filter through, creating a bright yet serene ambiance. Linen is breathable and helps in maintaining air circulation, making it perfect for those hot summer days.
Opt for light, neutral colours like white, beige, or pastel shades to enhance the cooling effect.
These tones also help create a calm, sun-washed interior aesthetic often associated with Mediterranean and Scandinavian summer design styles.
Sheer and voile curtains
If linen isn’t quite airy enough for your needs, sheer and voile curtains are ideal if you want to maintain privacy while still letting in plenty of natural summer light.
They add an ethereal touch to any room and can be paired with heavier curtains for a versatile, layered look. Sheers and voiles are great for creating a breezy atmosphere and can be found in various patterns and colours to suit any décor.

Blackout summer curtains
Summer days are long and bright, but while this is great in certain circumstances, sometimes it’s better to be in the dark. Blackout curtains are a fantastic choice to help you best control light levels in a room.
These curtains are designed to block out all light, making them perfect for bedrooms or living rooms where you might want to take a nap or watch a movie during the day. Despite their name, blackout curtains are made by adding a special blackout lining to the fabric. This flexibility means you can enjoy the practical benefits of blackout curtains without compromising on style.
Thermal summer curtains
While they might sound like something you’d use in winter, thermal curtains are also excellent for summer and keeping a room cool. Just like blackout curtains, curtains can have a special thermal lining that blocks heat, keeping your rooms cooler and more comfortable.
By forming a thermal barrier between the window and the sun, thermal blinds are equally effective in the warmer months. Because the thermal fabric blocks hot air, if the hot air is outside the window, it will keep the room nice and cool in summer, then block the hot air from escaping during the winter.
Why installation matters as much as fabric
Choosing the right curtain type is only part of it. How you hang them is just as important, and this is where many people lose a lot of the benefit they expected.
In many homes, curtains are hung:
- too close to the window frame
- too narrow to fully cover the sides of the glass
- without enough clearance from the wall
These gaps are where heat and light sneak in, regardless of how good the fabric is. More effective setups usually involve:
- wider curtain poles that extend well beyond the window on each side
- floor-length curtains for full coverage top to bottom
- layering sheers with heavier panels so you can adapt throughout the day
Small adjustments like these often have more impact on room comfort than changing fabric alone.
Is it better to keep curtains closed in summer?
In the hottest parts of the day, it is generally better to keep curtains closed on sun-facing windows to help block excess heat and keep rooms cooler. However, opening curtains in the early morning or evening allows natural light and airflow to freshen up your home. Using curtains strategically throughout the day can help maintain a comfortable temperature without relying on artificial cooling.
For added convenience, some people also consider electric curtain tracks that can be scheduled to automatically open and close at set times, helping to manage heat and light even when you are not at home.
Our top tips for choosing the best summer curtains
The most effective approach is not to focus on a single fabric or curtain type. Instead, think in layers and adjust them throughout the day. Here’s our checklist:
- Colour Matters: Lighter colours reflect heat, keeping your rooms cooler. White, cream, and pastel shades are ideal for summer, but so too are juicer, vibrant shades of blue, yellow and green.
- Fabric Choice: Natural fabrics like linen, cotton, and silk are breathable and help in regulating indoor temperatures. The way they softly move in the breeze also adds to the overall aesthetic.
- Layering: To make your windows ideal for the year round, combine sheer curtains with heavier curtains or blinds to have flexibility in controlling light and temperature depending on the requirements of the season.
- Length and Fit: Ensure your curtains cover the windows completely to block out maximum sunlight. Extend your pole well beyond the window frame on each side to eliminate side gaps. Floor-length curtains can add a touch of elegance and further insulate your rooms while shorter curtains offer a more youthful, contemporary look.
- Invest in quality: Curtains can last a long time if well chosen and maintained. At Blinds Direct, all our products are made to such high standards that we offer a five-year guarantee on all the curtains that leave our Yorkshire factory.
The right summer curtains can transform your living space into a cool, comfortable haven while enhancing your home’s aesthetic appeal. Whether you prefer the breezy elegance of linen, the functional efficiency of thermal insulated curtains, or the shimmer of silk, there’s an option for every taste and need.
Which curtains are best for summer?
There isn’t one single type of curtain that works for every home, but the best summer curtains are usually lightweight, breathable, and light in colour. Linen, sheer, and voile curtains are popular choices because they help let in natural light while keeping rooms feeling cool and airy. For more control over heat and brightness, blackout or thermal-lined curtains can also be used depending on the room and its exposure to sunlight.
