However, there are certainly a few factors that need to be taken into consideration. Before deciding on the blackout curtain liner, you also need to figure out what type of blackout curtains you currently have at home. Unlike regular curtains, blackout curtains are generally constructed with sturdier material to prevent traces of light from entering.

What are Blackout Curtains?

Blackout curtains are essentially curtains that help prevent light from penetrating into the bedroom, living room, or wherever the curtains are hung. Outside light can interfere with the circadian cycle and result in poor sleep quality. Hence, blackout curtains are important for individuals that may work during the night time, and require quality sleep during the day time. It also helps to ensure that babies and young children who sleep during the day are getting adequate and restful sleep.

While blackout curtains are mainly used to block out light, they also usually come with added features such as temperature insulation. This helps bedrooms to stay cool during the warmer months, and warm during the colder months. As it’s constructed with thicker material, blackout curtains can also help in reducing noise levels.

What are the Different Blackout Curtains?

While not specifically curtains, blackout curtains refer to any drapes, shades, blinds or even curtains that help with blocking out light, noise reduction, and aiding with insulation. Blackout curtains are constructed through a unique manufacturing process where foam layers are applied to raw fabric such as polyester or microfiber. The addition of these materials helps with increasing density and opacity to prevent light from passing through. These foam layers are also known as ‘passes’. In regard to blackout curtains, they usually fall into two categories of either two-pass or three-pass.

Two-pass usually means that there’s one layer of black foam applied to the fabric, and another white foam layer applied to the reverse side of the black foam. As the black foam can be visible through the layer of white foam, it can give the curtains an uneven look. Hence, individuals tend to add a blackout curtain liner to provide a more even look.

Three-pass blackout curtains on the other hand have two layers of white foam and a layer of black foam in between the white layers. While these curtains are usually more expensive, they’re also usually more aesthetically pleasing and do not require a blackout curtain liner.

What are Blackout Curtain Liners?

Blackout curtain liners are usually added to blackout curtains to help keep out light. They are usually sold separately but are also widely available.
