Control Light & Noise and Save on Energy Costs with Blackout Curtains

Did you know that in World War II, blackout curtains were used to conceal light from Nazi aircraft that were likely to bomb a structure if they saw light emanating from within? Well, that terrible war started because of greed and the quest for power may be over, but blackout curtains still find their way into many homes and commercial spaces. Here’s why:

1. Blackout Curtains Block Light

Blackout curtains block out outside light from entering in and vice versa. There are many people who have jobs that keep them up all night long, and keep them asleep almost all day. These unusual sleeping habits could lead to health problems in the future. There are different types of blackout curtains available, some that claim to block up to 99% of light.

These curtains are great for simulating night-time environments, thereby facilitating undisturbed sleep patterns, and reducing health problems. People in northern cities, where the sun can be high up in the sky for 20 or more hours a day, can benefit quite a bit from these curtains. If you have a home theatre system, you could simulate the complete darkness of a movie theater experience with the use of blackout curtains.

2. Blackout Curtains Block Ambient Sound

Along with light, there are some blackout curtains that are said to block filter out about 40% of outside ambient sound from entering the room through the windows. This is another salient feature for shift workers who find themselves needing to catch up on their rest during the day. The day time comes with its own set of sounds which normally cannot be blocked out, such as lawn mowers, cars, street noise, kids playing, garbage trucks, and more. Blackout curtains work well towards reducing these noises and offering you a sound sleep.

3. Blackout Curtains Save on Energy Costs

Another outstanding feature of blackout curtains is that they help to reduce the amount of money you spend on energy. During the winter, blackout curtains trap heat within the room so that you don’t have to turn the heat up in your home. In the summers, these curtains reflect light and heat out of the room, so you don’t need to turn your air conditioner on much. These seasonal benefits can really go a long way in conversing energy costs on cooling or heating your home. In fact, when you start using blackout curtains, you will notice a substantial reduction (in some cases, up to 25%) in your utility bills and greenhouse gases.

Blackout Curtains Have Fabulous Style & Design

Don’t be fooled by the name ‘blackout curtains’. If you are thinking of dark, dingy, drab pieces of fabric hanging over your windows, you are mistaken. Blackout curtains actually come in a delightful array of colors, fabrics, and style to add a touch of class to any home or commercial establishment.
