Seismic Rx Overview: ESR-1308 Code-Compliant Solution

ICC-ES recognizes the Armstrong Seismic Rx Suspension System as a code-compliant solution (ESR-1308). This evaluation and confirmation by ICC-ES provides evidence supporting the Armstrong Seismic Rx Suspension System as a code-compliant alternative to IBC requirements.

Seismic Rx Saves Time and Money

Seismic Rx has an ICC-ES evaluation which allows the utilization of 7/8" wall molding for ceiling installations in IBC Categories C, D, E, and F. The ICC-ES allows you to meet seismic code without the risk of delaying your construction schedule

Armstrong Ceiling Solutions offers an ICC-ES approach to installations in IBC Categories C, D, E, and F. The 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

Seismic Rx Benefits in Category C

  • Easier to square the system by cutting tight to adjoining walls
  • Tighter, more secure installation
  • Eliminate stablizer bars

Seismic Rx Benefits in Category D,E,F

  • Reduce material costs by using 7/8" molding
  • Eliminate stablilizer bars
  • Eliminate installation hassles from 2" wall molding

ESR-1308 Lists Specific Armstrong Components and Methods of Installation

The performance of the Armstrong Seismic Rx Suspension System is based on a specific combination of components and method of installation. Other manufacturers’ components and installation methods were not tested and are not covered in ESR-1308. Substitution of other components puts the system at risk and is not allowed by the ESR report.
