Self-closing, steel fire rated windows and doors, 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. 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 products address NYC Fire Code Regulations, often required in Lot Line situations to prevent the spread of fire: See NYC Fire Code Regulations
