Fire Door Ratings: E, EW & EI

Fire Door Ratings for Industrial Warehouses and Production Facilities: E, EW, and EI

Fire safety is critical in industrial environments, whether in warehouses or production facilities. Properly specified fire doors protect staff, stock, machinery, and production lines while ensuring compliance with fire regulations. The most common fire door ratings are E, EW, and EI, each offering different levels of protection. Tekta, a leading UK provider of industrial fire doors, supplies solutions designed for both warehouses and production facilities.

E-Rated Fire Doors (Integrity)

An E-rated door provides integrity, meaning it prevents flames and hot gases from passing through for a specified period (e.g., E60, E120). In warehouses, these doors are ideal for dividing storage zones and slowing fire spread. In production facilities, E-rated doors can separate machine halls, assembly areas, or chemical storage rooms, limiting the spread of fire between sections.

Limitation: E-rated doors do not stop heat transfer. Surfaces can become hot enough to ignite nearby stock or materials.

EW-Rated Fire Doors (Integrity + Radiation Control)

EW-rated doors combine integrity with reduced radiant heat, keeping the non-fire side cooler and safer for staff and sensitive materials. They are especially valuable in escape routes, corridors, and high-traffic areas in warehouses and production lines where workers may need to pass close by during evacuation.

EI-Rated Fire Doors (Integrity + Insulation)

EI-rated doors offer the highest protection, combining integrity with insulation to keep temperatures low on the safe side. This is critical in production facilities, where flammable materials, sensitive machinery, or chemical processes may be present. EI doors not only prevent fire and gas penetration but also protect equipment and production lines from heat damage.
