This advanced wall system has been independently tested and verified to deliver 480 minutes (8 hours) of continuous fire resistance under ASTM E119. During testing, the assembly withstood peak furnace temperatures of 2,075°F and successfully passed the rigorous ASTM E2226 hose stream test, demonstrating structural integrity following prolonged thermal exposure. Constructed using 3B’s proprietary non-combustible material, the system provides reliable, maintenance-free protection for critical infrastructure.
Designed for the most demanding environments, the FR480TM represents one of the highest fire- resistance ratings available for precast wall systems. Achieving a full 8-hour fire rating demonstrates the system’s exceptional durability and ability to perform under severe fire conditions, providing an added level of resilience and confidence for facilities where uninterrupted protection is essential.
