The FD ratings are specifically reserved for wooden doors while the E ratings are for fire-resistant glass doors.
The E classification additionally signifies the unchanged level of transparency in the glazing on exposure to heat or fire which would assist in capturing the most amount of possible visibility. The number tagged along with the E classification states the number of minutes the glass door would withstand the spread of fire and smoke. The spread of radiant heat is best contained by the EI, followed by EW classified glass doors to a lesser extent. The inability to contain the spread of radiant heat is the only comparative limitation applicable to the Class E fire-resistant glass doors. The ratings reflect 30 minutes of fire resistance with FD30 and E30 respectively; FD60 and E60 for 60 minutes of fire resistance and doors with both fire and smoke control are awarded FDS or ESa along with the cleared duration mentioned.
