Passive Fire Protection
When Fire Starts, Containment Is Everything.
McAllister designs and fabricates passive fire protection solutions that work without activation, intervention, or power — containing heat, limiting flame spread, and protecting people and property from the moment a fire event begins. Our solutions are engineered for environments where fire risk is real and the consequences of an uncontrolled event are severe.
From EV battery fires to commercial facility fire containment, our passive systems are custom-fabricated to fit specific applications, enclosure types, and regulatory requirements across vehicle, industrial, and built environment applications.
No Activation Required Passive solutions work from the moment of installation, providing continuous protection without triggers, power, or human intervention.
Custom-Fabricated to Fit Every solution is engineered to the specific geometry, enclosure, and performance requirements of the application it protects.
Broad Application Coverage From individual battery packs to pallet racking systems and building fire curtains, our solutions address fire risk across a wide range of environments.
Built for Compliance Engineered to support increasingly stringent fire safety standards across automotive, energy storage, and commercial building applications.
PRODUCT TYPES
Penetration Seals
Engineered penetration seal systems designed to maintain fire, smoke, and thermal barriers where cables, pipes, and conduits pass through walls and floors.
Fire Curtains
Flexible, high-temperature fire curtains designed to compartmentalize spaces, block flame and smoke spread, and protect building occupants and adjacent areas during a fire event.
Fire Containment Related Protections
Engineered assemblies and barriers designed to contain fire within a defined zone, limiting structural damage and protecting surrounding equipment, inventory, and personnel.
