Supress Sound-Engineered Drywall Earns 60-Minute Fire Rating in UL-Qualifying Testing

San Rafael, CA, July 30, 2008 - Supress Sound-Engineered Drywall has earned a 60-minute fire-resistance rating in UL-qualifying testing conducted in accordance with the ASTM E 119 fire testing method for building construction and materials.

"This preliminary analysis confirms our belief that Supress is a high performing product that not only provides superior sound suppression but is also a safe and reliable alternative to multiple layers of traditional sheetrock," said Gregg Jacobs, chief operating officer for Supress Products, Inc. "Our next step is formal UL (Underwriters Laboratories, Inc.) certification."

The fire-resistance rating was determined via two independent tests, each incorporating a different residential wall construction and panel thickness of Supress Sound-Engineered Drywall. Conducted by Southwest Research Institute, the first test paired ¾-inch Sound-Engineered Drywall with a non-load-bearing wall assembly of 20-gauge, 3 5/8-inch steel studs placed 16 inches on center. The second test, by Western Fire Center, was conducted with a load-bearing 2 x 4 wood-stud wall assembly finished with 5/8-inch Sound-Engineered Drywall. In each instance, the Supress product achieved a fire-resistance rating of 60 minutes-a critical first step in the overall UL certification process.
