How long can fire-resistant glass prevent fire?

The duration for which fire-resistant glass like EI30, EI60, and EI120 can resist fire varies based on their respective European standard classifications. EI30: This grade offers a standard fire resistance period of approximately 30 minutes. During this time, the glass maintains its integrity, limiting the transmission of heat and flames, allowing for a safe evacuation of people and slowing down the spread of fire within the building. EI60: An EI60-rated glass provides significantly more resistance. It can withstand fire conditions for up to 60 minutes. The higher rating means the glass maintains its structural strength longer, creating a safer barrier between rooms or zones, giving ample time for firefighters to arrive and extinguish the flames. EI120: As the name suggests, EI120 glass boasts the longest-lasting fire resistance of all three, lasting up to 120 minutes. This type of glass is typically used in critical applications where extended periods of fire resistance are required, such as in commercial buildings with multiple floors or those housing sensitive equipment. It's important to note that these ratings are based on tests that evaluate not only the resistance to heat but also the ability to self-extinguish when subjected to high temperatures. The choice of fire-resistant glass depends on the specific fire scenario and the level of protection needed in each application. In all cases, the main objective is to minimize damage, protect lives, and facilitate a controlled evacuation process.
