FIRE RESISTANCE GLASSES
There is three type marking for fire proof glass classification.
- E = Flame resistant,product keeps its integrity.
- W = Limited radiation,avoids radiation within its time.
- I = Isolation,not to transfer the heat to another side within its time.
The available periods are 30, 45, 60, 90, 120 minutes.
|E (time)||Flame resistant|
|EW (time)||Flame resistant and avoiding limited radiation|
|EI (time)||Flame resistant and keeping heat|
The thickness of fire proof glasses varies according to exterior or interior applications. If a fire proof glass is used for double glazing unit,it is obligatory that fire proof glass has to replaced against possible fire danger.
