What makes the best blackout curtain fabric?

The benefits of blackout curtain fabric

Before delving into the fabric options, let's look at the many benefits blackout fabrics offer.

Light blocking

Blackout curtains effectively block out sunlight, streetlights, and other sources of external light, allowing you to create a dark environment conducive to sleep or relaxation. Choosing high-quality blackout fabric ensures you can block up to 99% of light coming in.

Energy efficiency

Blackout curtains can regulate the temperature in your home, keeping it cool in the summer and warm during the winter months. The curtains can also save money on your energy bills with their insulation properties.

Noise reduction

The thickness and density of blackout curtain fabrics also reduce noise levels, absorbing sound and providing a quieter and more peaceful indoor environment.

Privacy enhancement

Blackout material enhances your privacy by blocking people from seeing into your home. They're great in busy areas where your personal space is often compromised.

The most effective blackout fabrics 

Most blackout curtain fabrics use polyester as a solo material or combine it with other fabrics. Polyester is a synthetic fabric that boasts affordability, durability, and superior light-blocking qualities.

Let's look at the most popular polyester combinations.

Polyester and cotton

Polyester and cotton are a common combination for clothing and blackout curtain fabric because the two balance each other out perfectly. While cotton isn't as effective as polyester at blocking light, it has aesthetic appeal and is eco-friendly.

The combination of polyester and cotton often uses polyester as the insulator and cotton for the outer layer, creating an elegant look. It also 

allows you to take advantage of the light-blocking properties of polyester while enjoying cotton's comfort and visual appeal. The outer layer of the curtain can be made from cotton fabric, providing a pleasing appearance and allowing air circulation. The inner lining can be constructed using polyester fabric with a dense weave, ensuring maximum light blocking.

Heavy microfibre

Heavy microfiber is an excellent fabric for blackout curtains, especially if manufacturers use triple-weave technology. It can cut out light up to 90% and balances the room's temperature with its insulating features.


If nothing but the best will do, velvet could be the perfect fabric for your needs. It's effortlessly luxurious and has excellent light-blocking properties due to its thickness and tight weave.

The plush texture of velvet also contributes to its blackout capabilities, and the heavyweight can offer further insulation benefits.

However, velvet is expensive, so there are cost implications to consider.

Choosing the right blackout fabric

Now that you know more about the different blackout fabrics, it's time to consider which suits your needs. Here are the most important factors to consider.

The fabric

Ensure that the fabric you buy is heavy-duty and does not allow the light to pass through. Semi-transparent materials may offer light blocking, but they will not last long. Choose a fabric that is denser than others since it will give more light protection.


Do all blackout curtains come in black? Well, blackout curtains are available in shades like white, blue, grey, and more, so don't worry about changing your décor.

You can also find modern styles that come in vibrant shades and patterns, ensuring you don't have to compromise on style.


Most importantly, consider your budget and choose a blend that aligns with it. There's no point spending money you don't have on velvet when a cotton and polyester blend is still an excellent choice.
