Tested Seismic Solutions
Armstrong Ceiling Systems are rigorously and independently tested to resist seismic actions. Learn more about the testing process and why Armstrong is the leader in delivering seismic solutions.


  • Comprehensive solutions for Two Way and Dry Wall Ceiling Systems
  • Robust to resist lateral forces and maintain structural integrity during a seismic event
  • Minimises panels and plasterboard sheets from dislodging and blocking evacuation paths
  • Enhances the safety of building occupants

Armstrong Seismic Design Calculator

The Armstrong Seismic Design Calculator, when applied with the Seismic Design Guide - enables correct application of various Armstrong Suspended Ceiling Grid Systems, including PeakForm (Steel), Blue Tongue (Aluminium) and DGS . Based on specific project information, the Calculator will generate data* on the required: Perimeter Seismic Gap, Bracing Types and Perimeter Fixing.

*Note: This data must be certified by a qualified engineer.
