ARMOROC is a structural cement board (cement bonded particle board - CBPB) used in the construction of fire-resistant roofs, floors, walls and a variety of other applications including modular, SIPS & OEM. By combining the physical properties of Portland Cement with the strength of mineralized wood fibers, ARMOROC is well suited for applications where durability is a concern.
Important: Confirm products meet local code before specifying, purchasing or installing.

- Important notes about our diaphragm design:
- Addendum A (page 25) has the test results including the glue.
- To comply with the Armoroc UL & MEA fire-rated assemblies, which do not include any glue, we have tested the shear diaphragm without glue in the joints. Always check that your fire-rated assembly is in agreement with your diaphragm design regarding glue where applicable.
- We are publishing the ultimate shear value, providing the engineer the opportunity to apply the appropriate safety factor required for wind / seismic based on the preferred method of load calculation for each project.
