In the world of building safety, fire protection is often viewed as a checkbox—something to meet code and move on. But in today’s complex environments, that mindset is no longer enough. From hospitals and high-rises to warehouses and schools, the stakes are too high for minimum standards.
At ASTA America, we believe fire-rated doors should do more than just pass inspection. They should actively contribute to the safety, efficiency, and resilience of the spaces they protect. That’s the thinking behind our latest innovation: the 500i Series Insulated Rolling Fire Door.
Whether you're designing for a hospital, high-rise, or industrial facility, the 500i Series delivers next-level protection with the added benefit of thermal insulation—a critical feature in energy-conscious construction.
why Fire protection needs a rethink
Fire-rated doors are often the last line of defense in an emergency. But they’re also part of the everyday operation of a building. That means they need to be:
- Reliable under pressure
- Efficient in energy use
- Durable in high-traffic environments
- Integrated with modern safety systems
Too often, facility managers are forced to choose between fire protection and thermal performance, or between safety and aesthetics. The 500i Series is designed to eliminate those trade-offs.
introducing the 500i Series: insulated fire protection, elevated
Designed for high-performance fire resistance and thermal insulation, the 500i Series is the ideal choice for facilities that demand more than just code compliance—it’s built for environments where safety, energy efficiency, and durability are non-negotiable.
Key Features:
- UL fire ratings up to 3 hours for critical containment
- R-Value of 4.7 with mineral wool insulation for thermal efficiency
- Sizes up to 30’ wide or 30’ high (not to exceed 600 square feet)
- Fail-safe activation via fusible links, smoke detectors or alarms
- Durable galvanized steel slats with 24-gauge backer
"10 years ago, fire-rated service doors were mainly used on interior walls and remained in the open position at all times, waiting for a signal to drop. Today, with more stringent fire codes and requests for fire-rated products, our customers are using these products as everyday service doors, including placement on exterior walls. By developing our new insulated, fire-rated 500i product line, customers can meet these stringent requirements while maintaining their climate-controlled facilities with ease."
—Cory Silverberg, ASTA America Product Manager
