California’s increasing fire danger, driven by prolonged droughts, elevated temperatures, and climate change, has placed building safety under intense scrutiny. The state’s Wildland-Urban Interface (WUI) regulations and stringent building codes require construction materials that not only meet aesthetic and performance demands but also provide proven fire-resistant properties to protect lives, property, and infrastructure.
Longboard® building products, constructed from 100% extruded aluminum, present a compelling case for fire-safe building design in California. Unlike wood and other combustible cladding materials, aluminum does not ignite, burn, or contribute fuel to a fire. This fundamental material advantage allows Longboard® to meet California’s strictest codes while enhancing long-term resilience and occupant safety.
Technical Features for Fire Safety
- Extruded Aluminum Construction: Does not burn, char, or contribute fuel to fire events.
- Reduced Flame Spread: Unlike wood, aluminum remains dimensionally stable at elevated temperatures without releasing flammable gases.
- Elimination of Fuel Load Risk: Reduces combustible content in a building envelope, directly lowering the risk of fire propagation
- ASTM E2768-11 (Extended Duration Surface Burning): Achieves Class 1 Fire Rating with third-party validation.
- Third-party tested – ASTM E2768-11, Class 1 fire rating
Integrated Building Safety Benefits
Thermal Efficiency & Fire Resistance
- Aluminum cladding enhances thermal performance while resisting ignition and flame spread.
- Protects structural assemblies by reducing radiant heat transfer to underlying combustible substrates.

Corrosion & Weather Resistance
- Maintains performance in California’s coastal, wildfire-prone, and high-wind regions.
- Offers rear-ventilated rain-screen (BV/D) capability, improving moisture management and fire-safe wall design.
Longboard’s aluminum cladding eliminates the risk of siding materials fueling a fire. This is critical in WUI-mandated construction, where siding, soffits, and screens must demonstrate resistance to direct flame and radiant heat exposure.
California’s fire safety challenges demand robust, code-compliant building solutions that eliminate combustible fuel sources while ensuring multifunctional performance. Longboard ‘s extruded aluminum systems present a proven, non-combustible, and environmentally responsible building envelope strategy.
Backed by rigorous certifications, Longboard enables architects, developers, and municipalities to align with California’s fire-safe building code strategies while enhancing sustainability, occupant health, and long-term resilience.
