USG Suspension System Seismic Solutions went head-to-head against Armstrongís seismic ceiling system at the Earthquake Engineering Research Center at the University of California, Berkeley. Both systems were tested on an Earthquake Simulator machine, a piece of equipment thatís made to shake. Really shake.
The results the test showed are truly dramatic. We took the required standard and turned the dialóall the way up to a realistic seismic event at the Berkeley facility. And we still passed. The competition, however, did not.
