Fire protective glass (E or EW) primarily blocks flames and smoke. Fire resistive glass (EI) goes further by also blocking radiant and conductive heat transfer, providing a true thermal barrier.
EI-rated glass offers superior protection by containing fire, smoke, and dangerous heat, providing crucial evacuation time, protecting assets, and maintaining structural integrity.
Fire rated glass(which is often referred to as fire-resistant glass,fire protection glass,anti fire glass or fireproof glass) is a specialized glazing product designed to act as a barrier against fire, smoke, and heat transfer for a specified period, helping to contain a fire and allow safe evacuation.
