Integrity (E)

Integrity, meaning the glazing can withstand the designated minutes against the flames and hot gases penetrating through to the unexposed glass face, i.e. if no flames or hot gases occurred on the non fire side before 1 hour it would be E60 rated.


Radiation and Integrity means the glass offers protection against flames (E) but also the heat that emits from the flame.  Heat radiation through to the non exposed side should remain below temperatures sets by the standards. value of 15kW/m2 reducing the radiated heat to other materials and people.
