Fire Rated Series: OWM Revolutionized Construction Industry

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 the window is exposed to temperatures up to 1600 degrees Fahrenheit.  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.
