Blackout vs. Room Darkening Curtains – Difference in the Numbers

Last updated on November 25, 2021

Here’s what the difference between the blackout curtains and the room darkening curtains is in the numbers. Read on!

In a nutshell:

  • Blackout curtains block 99% to 100% of light.
  • Room darkening curtains block 85% to 95% of light.
  • Blackout curtains are heavier and have more layers.
  • Room darkening curtains can be one-layer and look like real drapes.

When choosing blackout curtains, there are two main types to choose from — blackout curtains and room darkening curtains — though there are more alternatives. Both types block light from entering a room. However, there are differences between the two.

Blackout curtains are designed to completely block light from entering into a room, while room darkening curtains only partially block light from entering into a room.

If you want to get the best value for your money, you should consider buying room darkening curtains because they cost less. However, if you are looking for pitch black, you should opt for blackout curtains because they will allow you to sleep even during the day.

What's Inside?

What Are Blackout Curtains?

A blackout curtain is a type of window treatment that blocks all daylight from entering a room. This is done by using a fabric material with an opaque layer (or multiple layers). These fabrics are usually made from polyester or a blend.

The most common use of these curtains keeps rooms in hotels, motels, and other places where people stay during long trips. People who travel often have to spend many hours in their hotel room. During this time, they need to sleep well so that they can wake up refreshed.

These curtains are also helpful when you have children who take naps during the day. They are also irreplaceable in nurseries to provide the darkness for better sleep for the baby.

What Fabric They Are Made of?

Different types of fabrics can be used to make blackout curtains. Some of the popular ones include silk, cotton, rayon, microfiber, and others. What’s essential is that blackout curtains are made of multiple layers. The layers block the light but they can also provide thermal insulation and block noises.

What Are Room Darkening Curtains?

Room darkening curtains are a little different from blackout curtains. Room darkening curtains and shades do not completely block light from entering a room but instead let some light through. This is done by making the curtains from a triple weave fabric that’s denser and lets only little light through.

You can use room darkening curtains to make rooms darker during the daytime. For example, if you live in a sunny area, you may find yourself waking up early in the morning due to the bright sunlight. To avoid this problem, you can install room darkening curtains in your windows.

You can also use room darkening curtains to help you sleep better at night as well as prevent anyone from seeing into your room. When you go to bed, you may find that it is difficult to fall asleep because of the brightness of the lights. By installing room darkening curtains in your bedroom, you can reduce the amount of light coming in through your windows.

What Fabric They Are Made of?

Room darkening curtains are typically made of triple weave fabric. Triple weaving involves weaving two threads over each other three times. The result is a denser fabric than single weaving.

They are also made from fibers such as acrylic, polyester, polypropylene, and others. However, there are no specific requirements regarding what kind of fiber you should use. You need something that will allow light to enter a room while blocking out more harmful UV rays.
