CAL FIRE currently lists the AL13® Plank System for wildfire-area use as exterior wall siding.
The listing, 8140-2359:0001, appeared in the September 2025 OSFM WUI Listed Products Handbook and remained active in the live Building Materials Listing on August 25, 2026. It expires June 30, 2027.
The listed system uses solid extruded aluminum cladding, available in 4-inch and 6-inch plank profiles and 12-foot lengths. AL13 documents wall, soffit, and ceiling applications, while the state listing specifically covers exterior wall siding in category 8140. It identifies the system as noncombustible under ASTM E136; the documented fire standards also include ASTM E84.
The listing applies to the specified assembly, not every product sold under the AL13 name. AL13 documents PE, FR, and solid-aluminum plank variants, so the ordered plank construction must match listing 8140-2359:0001. The frame components, fasteners, and installation details must match as well. For inspection, confirm both the exact system and the listing’s current status, particularly for work completed near or after its June 2027 expiration date.
