FIRE RATED CLASSES

MADE SIMPLE

Uncomplicating fire-rated door types

When a fire resistant door has been tested, it gets a classification showing the duration in minutes it resists fire for.

Split into different categories, the classifications indicate how the door will prevent the passage of flames, smoke and heat transfer. This is represented as Integrity, Radiation and Insulation performance.

E - INTEGRITY

 

Fire integrity, denoted by the letter “E” followed by a number, indicates the duration a door can protect and
compartmentalise an area from the direct spread of flames.

Integrity only fire doors are a physical barrier against smoke and fire, providing essential protection for
occupants and property but do not prevent the transfer of heat.

EW - INTEGRITY & RADIATION

Fire doors that achieve the EW classification have the same level of protection as E but, in addition, will also deliver a reduction in the amount of radiant heat transmitted to the protected side.

The term “EW” followed by a number indicates the duration (in minutes) during which the door limits the radiant heat transfer to below 15 kW/m2 at a measured distance from the door.

EI - INTEGRITY & INSULATION

Class EI adds Insulation to the door and provides the most complete level of protection. EI provides a robust
barrier against heat and flames, surpassing even the most stringent requirements.

In addition, EI insulation excels at minimising heat transfer through the door. The designation “EI” followed by the duration (in minutes) provides fire resistance and insulation.
