FIRE RATED GLASS WITHOUT INSULATION (E, EW-RATED)


E-RATED GLASS

No flames or hot gases on the non-fire side The glass remains transparent in case of fire Monolithic glass based on Soda-Lime Wired glass, also as figured glass
	High heat radiation From the glass surface + Transmission Through the glass

Glass surface temperature app. T=550^oC (after 30 min)
Remain transparent in case of fire


EW-RATED GLASS

Same as Class E plus measured radiated heat in front of the glazing may not exceed15 kW/m2. EW glass is available in two optional specifications: Coated safety glass Float or toughened glass with interlayer

Coated Safety glass

Limited heat radiation From the glass surface + Transmission Through the glass

Glass surface temperature app. T=520^oC (after 30 min)
Reduced radiation by means of reflective coating
Remains transparent in case of fire - "Reflection"



Float or toughened glass with interlayer

Energy of furnace

Low heat radiation From surface No direct radiation through the glass stable insulating, cooling foam cracked / melted glass

Glass surface temperature app. T=265^oC (after 30 min)
Non transparent in case of fire - "Absorption"
