Our Blackout Curtain Buying Guide

Don’t you love staying at a hotel where the curtains are three layers deep and you never know what time it is when you wake up? Blackout curtains are essential for sleeping in or taking a nap. You’ll find all sorts of styles and patterns to freshen up your space and catch up on some much need sleep.

What makes a curtain or window treatment blackout? When referring to the term blackout, it means that the window treatment is made with a foam or opaque backing. This material then blackens or darkens the room by preventing the sunlight from flooding the room when they are closed. The most common material used to make the curtains is triple-weave polyester. This fabric keeps them light and effective. The NICETOWN Grommet Blackout Curtains, 2-Panels are made from triple-weave fabric and as an added feature are wrinkle-free.

In addition, blackout curtains are not the same as drapes. Curtains are defined as one layer of fabric that filters light. Drapes feature more than one layer and often feature an entire blackout layer. Drapes are typically dark and very heavy. When shopping for blackout curtains, you will find they have blackout features built into the layer of fabric or just a very thin layer sewn on the back, making them much more lightweight than drapes.

Blackout curtains are not only good for blocking out the early sunlight. These curtains can also keep your furniture from fading in strong UV rays. In addition, the curtains will keep your heat inside during the winter and the cool inside during the summer. One additional advantage of blackout curtains is their ability to reduce noise or reverb. If you have a large room with high ceilings, blackout curtains can help the space quite a bit. The Deconovo Grommet Blackout Curtains, 1 Panel offers outstanding insulation for those extreme temperatures.

As for style, don’t feel as if you have to compromise when buying blackout curtains. There are many varieties and colors to make your space look beautiful. Besides color, you can choose dramatic floor-length curtains, or you can decide which texture you like best. With all the options available, you will certainly find a set to complete your space.

Simplemost Fun Fact

The history of blackout curtains started during World War II. The enemies would fly over and drop bombs at night. As a result, the government established ‘blackouts’ so the enemy couldn’t see the lights on in homes. Every household had to keep their blackout curtains closed at night so no light could escape. Britain enforced the blackouts starting in 1939 to confuse the enemy pilots trying to navigate at night. This wasn’t easy for those who had stone-constructed homes or metal window frames. It became a burden for many to hang the heavy cotton fabric and to also remember to close all curtains at night.  Car headlights were even partially covered and as a result, car accidents jumped to a significant high. Crime also had a significant increase during the blackout period.

The Blackout Curtain Tips and Advice

  • Always measure your windows before you buy.
  • For the best price, look for a two-pack.
  • If insulation is a concern, look for an insulation rating or terminology.
  • Follow care instructions when laundering.
