Quiet Barrier™ Acoustic Quilts (4’x4′)



Sometimes you need an effective method of soundproofing that’s portable and not meant for long-term use but can still block high levels of unwanted sounds in challenging environments. Our acoustic quilts from Soundproof Cow are the perfect answer. Each 4’ x 4’ soundproof quilt provides 16 square feet of sound-absorbing, high-performance fiberglass covered in a non-porous vinyl.

Hang these acoustic quilt panels up or lay them down anywhere you expect to experience a high amount of unwanted sound in the short term. They’re perfect for the type of high-decibel airborne sounds you may encounter at construction sites, in airport hangers, near factory generators, in temporary recording studios and more.

Our sound-absorbing quilt is fire-safe with a Class A™ flammability rating, so you can use it in almost any environment or high-noise situation. They’re 1” thick standard, which is enough to block or significantly reduce most airborne noise that might otherwise penetrate the area where you require sound control, but we can provide 2” or 4” thick quilts upon request.

High levels of noise can be a significant safety hazard. If you’re managing a worksite where loud, heavy equipment is in use, failure to implement proper noise control could result in impairment to your employees, which is something you want to avoid for a host of reasons. Our acoustic quilts help solve the problem of not having the budget or ability (because you’re working in a location temporarily) to implement a more complex soundproofing solution.

Our soundproofing experts will be happy to talk with you about your needs and help you determine whether a 4’ x 4’ Quiet Barrier™ acoustic quilt is the right solution for your needs. Give us a call at 1-866-949-9269 for more information as soon as you’re ready for the perfect soundproofing solution.

The Quilts took a long time to get, I think about 4 weeks. I really liked using them because they were easy to put up and effective, and if I know I have a little bit of time before the project starts, I will always use the Barrier Quilts.
