Tested and trusted seismic solutions


In geographic seismic zones, and other building types requiring additional protection, building structures need to be properly designed and engineered to withstand seismic effects, while sustaining an acceptable level of damage. Our seismic solutions provide the additional security required for seismic resistance using specifically designed elements for minimised installation complexity with maximum performance. 

In addition to earthquakes, there are several other industries with associated risks (e.g. blast protection) where the use of seismic tested systems will provide additional protection for the ceiling:

  • Nuclear installations
  • Defence establishments
  • Chemical installations
  • Transport installations (with intermittent vibrations)

Seismic Rx® suspension system, for use with standard mineral and metal tiles, plus a customised Metal R-H 200 system, provide tested systems for buildings with seismic protection requirements.



Knauf Armstrong Seismic Rx®


ICC-ES recognizes Knauf Armstrong Seismic Rx® suspension system as a seismic code-compliant solution to meet ESR-1308. This evaluation and confirmation by ICC-ES provide evidence supporting the Knauf Armstrong Seismic Rx® as a code-compliant alternative to IBC requirements.


The performance of the Knauf Armstrong Seismic Rx® system is based on a specific combination of components and methods of installation.
