Fire resistant glass can withstand all kinds of dangerous environments. To determine the quality of the glass, an independent laboratory conducts tests and grades the material. Each glass is rated based on its tolerance to heat shock from extreme heat and cold water. Fire-resistant glass is usually made of polished wired or ceramic glass.
Fire-resistant glass is usually made of multiple layers of toughened glass and an expanded sandwich. When exposed to fire, the nearest layer of glass rapidly heats up and breaks into small pieces, while the remaining glass expands and repels heat and smoke. Fire-resistant glass is more suitable for buildings containing hazardous materials. However, it is important to note that fire resistant glass is not a substitute for ordinary glass in all cases.
Fire resistant glass also protects against smoke, flame and radiant heat. It's usually not 250 degrees Fahrenheit hotter than its surroundings. Fire-resistant glass is becoming more common in building codes, and will be used in many types of walls, doors, and interior Windows. Fire-resistant glass must meet certain requirements for structural strength and safety and help ensure occupant safety.
Fire resistant glass is generally more expensive than ordinary glass. Its main goal is to control fire, smoke and flames. It does not prevent radiant heat transfer, meaning that the object on the other side of the glass will still feel the heat. Fire resistant glass comes in many forms, including microcrystalline glass, wire glass and special toughened glass. It is also recommended for certain applications, such as switch panel glass and low radiation glass.
Fire resistant glass goes through the same testing process as other fire-resistant materials. The glass system and its components are installed in a furnace and generate fire internally. The fire must burn in the furnace for the specified time. This is done to keep the glass assembly intact. Its use in public buildings and elsewhere is growing.
