GLASS FOR FIRE RESISTANCE
In the event of a fire, fire-resistant glass stops the inflow of oxygen, de-fueling the fire. Stops the spread of flame, smoke, and hot toxic gases, can reduce radiant & conducted heat transmission.
Protects life and guards against property loss.
THE 3-MAJOR GOALS OF FIRE PROTECTION:
- Escape (agress) of building occupants
- Provide safe areas of refuge for trapped occupants
- Access to firefighters & emergency service personnel
- Containment within a limited zone or compartment
- Prevention of spread to neighboring structures
CONTINUITY OF OPERATIONS
- Typically an insurance requirement or an item of self-interest for building owner’s not a regulatory issue.
- Limit interruption of operations due to fire damage.
FIRE RATED GLASS CLASSIFICATION
Integrity glass, E classification: This is the most basic type of fire-resistant glass. When exposed to a fire, it prevents flames and hot gases from penetrating through to the unexposed side. It does not, however, stop heat from penetrating through the glass.
Radiation control glass, EW classification Like integrity glass, this classification of glass stops both flames and hot gases from penetrating through to the other side
Integrity and insulation glass, EI classification The EI classification is the highest of the fire-resistant glass classifications. When exposed to a fire, it prevents flames and hot gases from penetrating through, and also maintains the average temperature of the unexposed face to below 140°C.
