Nichiha Architectural Wall Panels (AWP)
This is a material class, not a wall or roof assembly listing. Listing 8170-2029:0005. A class is not a permit.
Nichiha documents its Architectural Wall Panel system as exterior rainscreen cladding made from 5/8-inch-minimum fiber-cement panels in 17-7/8-inch widths. CAL FIRE OSFM listing 8170-2029:0005 classifies the AWP material as ignition resistant after ASTM E84 testing with an additional 20-minute period; that material test is distinct from an hourly wall-assembly rating.
Kind: material-class.
Brand: Nichiha USA, Inc.. Listing evidence: OSFM WUI handbook 2026-08-25.

Listing 8170-2029:0005 is an ignition-resistant material classification based on extended ASTM E84 testing. It is not an ASTM E119 hourly wall rating and does not classify every wall assembly.
Match the exact AWP profile, minimum thickness, orientation, clips, fasteners, weather-resistive barrier, joint treatment, flashing, and installation instructions to the current OSFM data sheet and Nichiha literature.
