ABSC-26 AudioSeal® Combination Sound Blanket

The ABSC-26 AudioSeal® Combination Sound Blanket is a barrier septum composite for environments with high temperatures up to 500° F. These silicone-coated blankets are constructed with a one pound per square foot non-reinforced mass loaded vinyl sound barrier septum. They are also encapsulated with one-inch thick fiberglass matting on each side and quilted with a UV resistant vinyl coated polyester facing. This allows the ABSC-26 AudioSeal® Combination Sound Blankets to supply 360-degree sound absorption and sound attenuation in one efficient product.

Curtain panels are constructed with grommets across the top and mating Velcro® along the vertical edges for easy installation and layering. 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.

Cleaning and Maintenance:

Clean these acoustical blankets by using a vacuum cleaner or broom to remove the debris from the blanket surfaces. You may also clean any product surface that is not a scrim facing with an air hose or any non-solvent based cleaning product. We recommend typical “all-purpose cleaners” that contain ingredients such as water, detergents, and grease cutter. Similar suitable brand names are Formula 409, Top Job, Spic & Span, and Mr. Clean.
