Thermal Curtains and Soundproof Curtain – Do You Need Both?
Thermal curtains, also known as insulating curtains, have always been popular but have become even more so as the cost of energy rises. Thermal curtains are made to cut back the heat and cool air that often leaks through windows and hikes up the energy bill. The interesting thing is that thermal curtains often claim to not only cut back energy costs, but also reduce noise. What most people don’t realize is that there are already products in the market designed to cut back noise, and do so much more effectively. The great thing about a soundproof curtain is that it can be hidden behind insulating curtains, so you can’t see the difference but can definitely hear it.
Basically, if you’ve been looking at all the thermal curtains in the market, you’ve noticed that they sometimes claim to block sound, but usually don’t give an NRC test rating for their products. This is a red flag because NRC indicates how much sound a particular material will absorb at the most common frequencies.
That’s where the soundproof curtain comes in. By hanging a soundproof curtain behind insulating curtains (or even on its own), you will experience an incredible reduction in noise within your room. With an NRC rating of .7, a soundproof curtain (also known as a sound absorption sheet) absorbs nearly 70 percent of the sound waves in a space. This means that 70 percent of the echoes and reverberation caused by conversation, musical instruments, household appliances, and other bothersome noises are eliminated.
Some soundproof curtains are even made from natural materials, making it a very effective but much less expensive option to other sound absorption products, like foam or fiberglass. Just as thermal curtains are a great way to save money on your energy bill, adding an eco-friendly soundproof curtain behind existing curtains is a great way to help your immediate environment, as well as the greater one.
