Product Description

Plaintiffs alleged in publicly filed U.S. asbestos personal-injury and wrongful-death litigation that National Gypsum Company’s Audicote was a sprayed acoustical plaster product allegedly formulated with asbestos fiber blended into a plaster matrix. According to publicly filed asbestos litigation records, Audicote was allegedly spray-applied by hopper gun to ceiling deck undersides and acoustical surfaces in commercial, institutional, and educational buildings — providing both fire-resistance and sound-absorption performance.

The U.S. Environmental Protection Agency banned spray-applied asbestos fireproofing in 1973 under 40 CFR Part 61, and plaintiffs alleged that sprayed asbestos acoustical plaster fell within the scope of the ban. Plaintiffs alleged that Audicote with asbestos content was manufactured and sold through the 1973 EPA cutoff, with sprayed acoustical material remaining in place inside schools, hospitals, offices, and public buildings for decades.
