Product Overview

Heavy-duty temperature rise steel door for commercial applications

Temperature Rise rated full flush doors feature mineral board cores that provide a 250° temperature rise rating, or 450° at 30 minutes of test exposure, depending on hardware application. This makes these doors ideal for stairwells in multi-level buildings when occupants must evacuate in case of emergency. In the event of a fire, temperature rise doors minimize the heat transfer to the non-fire side of the door. Standard 90-minute and 3-hour fire doors available.

  • Mineral board core – 250°F (121°C) Temperature Rise rating or 450°C (232°C) at 30 minutes
