FIRE-RATED WINDOWS & DOORS.
Optimum has revolutionized the construction industry by offering the most comprehensive line of fire-rated steel windows and doors. With fire-ratings ranging from 45 to 90 minutes, Optimum’s Fire-Rated Windows are put through rigorous testing.
Initially, a “heat test” is performed, where-in the window is exposed to temperatures up to 1600 degrees Fahrenheit. Fire-Rated Windows also endure the “Hose Stream Test”, in which the glass holds fast even during this extreme change in temperature. When other windows made from materials such as aluminum, vinyl and wood are placed under these extreme conditions, they will poorly react in a Thermal Shock. Optimum Fire-Rated windows will hold their integrity.

FIRE-RATED SELF-CLOSING DOUBLE-HUNG WINDOW
Product Description
Optimum’s 45-90 Minute Fire-Rated Double-Hung Windows 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 has been through rigorous testing. Initially, a “heat test” is performed 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 Window & Doors will hold and maintain its integrity.
