If the code requires 2″ wall molding, how can Armstrong offer an alternative using 7/8″ wall molding?
The Armstrong BERC2 system was full-scale tested on a seismic table at the Structural Earthquake Engineering Systems Laboratory at the State University of New York at Buffalo. The appropriate section of the IBC code (Section 104.11) allows code officials to consider alternative construction methods. The BERC2 system solution is an “alternative construction method” properly governed by IBC section 104.11. Full-scale tests conducted validated that the BERC2 system performs in a manner consistent with the requirements of the 2000 IBC.
