Blackout curtains were originally used in Britain during World War Two to prevent interior light from being detected by Nazi planes. Today, they have multiple benefits, including reducing your heating bills.

The Three Main Functions of Blackout Curtains

Blackout curtains serve three primary purposes: blocking light, reducing noise, and saving energy.

1. Blocking Light

Some brands of blackout curtains can block up to 99% of light, making them ideal for people who work at night or live in northern cities where the sun is out for extended periods. They can also create complete darkness for home theater systems.

2. Reducing Noise

Certain blackout curtains can block up to 40% of noise, which is useful for those who work during the day or live in noisy areas.

3. Saving Energy

By trapping heat in during the winter and keeping light and heat out during the summer, blackout curtains can reduce thermal energy loss through windows by up to 25%. This reduction can lower your utility bills and greenhouse gas emissions.

Looking for blackout curtains? They can range from expensive high-end options to cheaper options under twenty dollars. You can find them at major retailers like Walmart, who sells the Eclipse brand. If you’re handy with a sewing machine, you can even make your own by adding blackout liners to your current curtains. Blackout shades and blinds are also options, with shades being comparable to curtains and blinds giving you the advantage of controlling light. Make sure to hang your curtains properly, and be aware of the material used – avoid vinyl curtains due to associated health risks.


1. What are blackout curtains?

Blackout curtains are specially designed curtains that can block out sunlight and other external light sources. They are typically made of tightly woven or layered fabric that is designed to absorb or reflect light, helping to prevent it from passing through the curtain. Blackout curtains are often used in bedrooms, nurseries, home theaters, and other rooms where light control is important.

2. How do blackout curtains save energy?

Blackout curtains can help save energy by blocking out sunlight and reducing the amount of heat that enters a room. This can help keep the room cooler, reducing the need for air conditioning and helping to save on energy costs. In addition, blackout curtains can also help insulate a room, reducing heat loss during colder months and further reducing energy usage.

3. Can blackout curtains help control noise?

Yes, blackout curtains can help control noise by blocking out external sound sources. The tightly woven or layered fabric used in blackout curtains can help absorb sound waves, reducing the amount of noise that enters a room. This can be particularly useful in homes located near busy streets, airports, or other noisy areas.

4. Are blackout curtains easy to install?

Yes, blackout curtains are generally easy to install and can be hung just like any other type of curtain. They are available in a variety of styles and sizes to fit most windows, and can be mounted using curtain rods, hooks, or other hanging hardware. Some blackout curtains also come with grommets or other features that make them easy to install and remove.

5. What are the benefits of using blackout curtains?

Using blackout curtains can provide a number of benefits, including better light control, improved energy efficiency, and reduced noise levels. They can also help protect furniture and other items from sun damage, as well as provide increased privacy and security. In addition, blackout curtains are available in a wide range of colors and styles, making it easy to find a design that fits your d├ęcor and personal style.
