Quiet Barrier™ Acoustic Quilts (4’x8′)



When you have a serious soundproofing job but don’t have the capability or funds to invest in a permanent soundproofing solution, order an acoustic quilt from Soundproof Cow.

Our 4’ x 8’ noise barrier quilt provides a full 32 square feet of sound protection in a portable, one-inch-thick sheet of fiberglass wrapped in non-porous vinyl. You can take and use these acoustic quilts just about anywhere where you need reliable soundproofing on a temporary basis. Our standard-size quilts are usually more than enough to dramatically reduce even some of the loudest sounds, but we can provide these quilts in 2” and 4” thicknesses as requested.

Our non-flammable (Class A™ flammability rating) quilts can be used in almost any environment. Lay them on the floor, use them like a curtain or hang them on a wall — these versatile, portable quilts are easy to use. Try them for temporary sound control situations like:

  • Construction sites: Place added protection for your workers from hearing damage and noise pollution stress in addition to reducing construction sounds that may annoy neighbors.
  • Recording studios: Hang these quilts on the walls of your garage or guest house for an instant soundproof recording studio, then take them down when you need the room for its original purpose.
  • Factories: A lot of factories have many loud machines. When they’re all working together, the sound can be deafening. Hang acoustic quilts on the doors or walls between the machine rooms and the employees, or in some cases, drape the quilts directly over the machines.
  • Other: Anytime you need to block unwanted sound but can’t afford or don’t want to install long-term sound barriers, let our Quiet Barrier™ acoustic quilts come to the rescue.

These quilts are large enough to handle some of your biggest soundproofing tasks, and they’re highly effective at blocking airborne noise. To learn more, give us a call at 1-866-949-9269.

We were having some issues with a freestanding machine motor dead center in our warehouse. It wasn’t the prettiest thing in the world but we were able to post all these Quilts around the enclosure, and it worked really well. I know these are advertised as temporary soundproofing but we’re going to keep this “rig” up for as long as we can.
