Sound the Way You Like

Our curtains can be used to block noise or improve acoustics. Our STC Sound Blocking curtains work due their inner linings. These linings are specialized, proprietary vinyl’s made exclusively for Quiet Curtains. The face fabrics used to construct the curtains have little impact on sound blocking. Let us know the needs of your project and we will recommend the best solution.

  • Proprietary lining blocks 15-20 dB
  • It reduces the volume of noise the human ear can hear by about 60% (the highest tested curtain on the market).
  • Up to 1.0 NRC Rating lab tested. This means that 100% of the sound is being absorbed by the curtain!
  • Three layer heavy duty construction
  • Excellent sound absorption

We installed the curtain yesterday and could not be more pleased! Quality of construction and fit were better than I expected and the bonus is it WORKS! Considerable reduction in echo and noise from the other side; can’t wait to give it a trial on Sunday.


Here’s a photo of the new curtains in our Cornell Kiplinger Theatre.

They look great. You guys did a super job for us.

I just wanted to let you know that the curtains you made for us are perfect!!! They were delivered on time on Friday, and we had them up in time for Easter Sunday. They look beautiful and blocked the majority of the noise. Thank you for building such a beautiful product. We look forward to doing business with you again in the future.
