Optimum’s 45-90 Minute Fire-Rated Doors are used in non-temperature rise applications and through various glazing options can be modified to address most fire-rated applications. Its narrow profiles providing open vision areas allows natural daylight without compromising life safety and design flexibility. The entire Fire-Rated line have been through rigorous testing. Initially, a “heat test” is per- formed where the window/door is exposed to temperatures up to 1600 degrees Fahrenheit. They will then endure the “Hose Stream Test”, wherein which the glass holds fast even during this extreme change in temperature. Where other units of different material will react poorly when placed under these extreme conditions; Optimum’s Fire-Rated Steel Door will hold and maintain its integrity.
