The ABSC-25 AudioSeal® Combination Sound Blanket is a sound barrier panel used to block and absorb sound for interior applications. The blanket has a septum encapsulated with fiberglass, allowing for both sound absorption and sound attenuation in one efficient product. These sound blocking blankets are an excellent choice to block and absorb sound.

The AudioSeal® acoustical blankets consist of a non-reinforced 1-lb per square foot mass loaded vinyl barrier between two layers of vinyl coated recycled fiberglass cloth faced 1” quilted absorbers. The sound attenuation blankets are constructed with grommets across the top and Velcro® along the vertical edges and can be custom sized.

Typical uses include industrial sound control. These blankets are commonly used as separator walls or divider partitions and to line the perimeter of an interior wall. The ABSC-25 AudioSeal® Combination Sound Blankets are Class 1 fire-rated and are a double duty sound blanket in that they work for both absorbing and blocking sound.

Standard 4′ x 8′ blanket panels may be ordered online. Other sizes and configurations are available, please contact us with your specific requirements.

  10. Araya Studios, LLC

    I'm using the blanket for an unorthodox purpose: to provide additional sound insulation in a recording booth. But even though this isn't the stated use of the product, it's working as well as I expected it would, and I would absolutely recommend it to others.

  11. Verified Customer

    It worked exactly as intended.

  12. Verified Customer

    Sound barrier.

  13. Verified Customer

    Not that easy to install.

  14. Verified Customer

    Works great. A little difficult to hang on wall but overall satisfied.

  15. Verified Customer

    Very high quality. Would definitely recommend to anyone interested in buffering sound. One tip: Make sure you account for the height of the base when measuring the height.

  16. Verified Customer

    The sound barrier blanket arrived in a timely manner, and works as advertised. Even though I have only one blanket up on a wall that needs 4, I already notice a significant difference. I too have a noisey neighbor that I'm trying to isolate myself from.

  17. Verified Customer

    Seems like a quality product, haven't hung the panels yet.

  18. Verified Customer

    Service elevator near proximity to guests to damper sound

  19. Verified Customer

    looks to be solid

  20. Verified Customer

    The blanket used for HVAC closet to reduce noise from forced air furnace.

  21. Verified Customer

    Works perfectly!

  22. Verified Customer

    I use this product as a sound barrier on my garage doors. I would recommend the product to any musician dealing with unwanted sound movement or penetration and needs the solution to be effective but portable/mobile. The product will very well made and I expect it to last for years.

  23. Verified Customer

    I use it as a sound barrier in my condo.
    Neighbors want to know more so I gave them the web site.

  24. Verified Customer

    Great Quality
    Used In A High School Performing Arts Center

  25. Verified Customer

    I use the product as a mechanism to block sound from neighbor.

    The apartment was not designed for two seperate lease holders and so we can hear too much from the other side. Further I couldn't even place hooks in the wall without modifying the lease agreement and the last thing I want is to spend any kind of significant money that I have to leave behind.

    These blankets work great!! Put them on a frame leaned them against the wall, and now he is so quiet I can barely hear the guy.

  26. Dan Moretti

    I just want to thank you and Acoustical Solutions for the window blanket. It does the job like advertised and is very well made. I am very happy with the purchase. Thanks very much for all your help!
