The AQFA-10EXT Exterior Absorber Sound Blanket is used to add sound absorption to exterior applications to reduce reverberation and echo. The AQFA-10EXT Exterior Absorber Blankets are quilted fiberglass absorbers (QFA) that feature UV and tear resistant exterior grade vinyl coated polyester quilted to 2-inch thick fiberglass batting, sewn with a Gore® Tenara® thread.

The AQFA-10EXT can be installed on existing solid surface. The quilted fiberglass absorber blanket reduces the reflection of sound waves by adding soft, porous, open-celled materials to an otherwise less absorbent surface. These blankets are often used to reduce sound from outdoor HVAC equipment, dust collectors or other equipment and can be installed on wood fencing or existing walls.

The quilted blanket may be configured as hanging panels or provided as roll goods. Standard sound blanket panels are constructed with all edges bound and grommets across the top and bottom edges. Rolls can also be supplied with unbound edges and typically do not include grommets unless otherwise specified.

These durable blankets have an NRC rating of 0.75 and weigh approximately 0.50 pounds per square foot. The AQFA-10EXT blanket is available in a variety of colors and stitch patterns and can be made in any size up to 4′ x 25′.

 AQFA10EXT Sound blanket panels or rolls are ideal for use in exterior applications.

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

9 reviews for AQFA-10EXT Exterior Absorber Sound Blanket

  1. Jean T.

    Great product. Fantastic people to work with.

  2. PM Environmental Inc

    Product was every bit as effective as promised

  3. John K

    Decent build quality, only one stitch a little bit frayed. Will see how it holds up long term. Ordered two, using one right now. Instantly reduced my sound problem (HVAC compressor).

  4. T H Watkins

    The sound absorbing blanket fits the intended space nicely. Since I needed to mount it horizontally, however, it would have been preferable to have support grommets in all four sides, not just the 2 short ends.
    I think the blanket has knocked the noise of 2 air conditioning condensers down some. The proof of the blanket’s effectiveness will be in the ears of my next door neighbor. If I don’t hear from him, he’s not hearing my a/c.

  5. Masrsh B.

    Didn't help as much as I hoped.

  6. W Forbes

    great product

  7. Verified Customer

    makes a big difference in commercial ac that the church next door has positioned close to our house, but would still like less noise!

  8. Verified Customer

    I built a two sided enclosure around my AC and the two blanket enclosure quieted the AC considerably.

  9. Verified Customer

    Great quality. I would recommend them to anyone.
