ARMSTRONG SEISMIC Rx® SUSPENION SYSTEM SAVES TIME AND MONEY
Armstrong is the only manufacturer to have an ICC-ES evaluated system utilizing 7/8" wall molding for ceiling installations
in IBC Categories C, D, E and F. The Armstrong Seismic Rx Suspension System offers a labor and cost saving method of meeting
seismic code without the risk of delaying your construction schedule.
Seismic Rx allows you to eliminate unsightly 2" wall angle in Category D, E, F seismic-compliant installations.
 
2" wall angles are prone to the following problems:
• Difficult to keep “tight” to wall
• Difficult to install corners
• Prone to twisting and warping
In IBC Category D, E and F – Armstrong Seismic Rx benefits include:
• Reduce material costs by using 7/8" molding
• Eliminate stabilizer bars
• Eliminate installation hassles from 2" wall molding

IBC Installation Requirements |
| D, E, F |
• Minimum 7/8" wall molding
• Grid must be attached on two adjacent walls – opposite walls require BERC2 with 3/4" clearance
• BERC2 maintains main beam and cross tee spacing; no other components required
• Heavy-duty systems as identified in ICC-ESR-1308 (refer to Suspension Systems listed on page 9)
|
• Minimum 2" wall molding
• Grid must be attached to two adjacent walls – opposite walls must have a 3/4" clearance
• Ends of main beams and cross tees must be tied together to prevent spreading
• Heavy-duty grid system
|
In IBC Category C – Armstrong Seismic Rx benefits include:
• Easier to square the system by attaching to adjoining walls
• Tighter, more secure installation
• Eliminate stabilizer bars
