Product Description

The PrivacyShield® Dual-Sided Absorptive Soundproofing Blanket, (formerly the ABSC-25 AudioSeal® Combination Sound Blanket), includes both sound blocking and sound absorbing material, making it an ideal noise barrier for interior spaces where excessive echo is a problem as well. These blankets are constructed with a 1 lb. per sq. ft. mass loaded vinyl sound barrier that is sandwiched between two layers of 1 in. thick acoustical fiberglass batting that is then quilted with a vinyl-coated fiberglass cloth facing. This allows our PrivacyShield® Dual-Sided Absorptive Soundproofing Blankets to provide 360-degree sound absorption and sound attenuation in one efficient product.

These sound attenuation blankets work like curtain panels. They are constructed with grommets across the top edge and Velcro® along the vertical edges which make them easy to hang, layer, and install. You may use these silicone-coated blankets in high temperature areas for machine and equipment enclosures or reduce and block sound for just about any application.

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 PrivacyShield® Dual-Sided Absorptive Soundproofing 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 up to 4 ft. x 25 ft. are available, please contact us with your specific requirements.
