Fire protection & fire protection classes

Here you will find information about fire protection and fire protection classes for our fire doors and security doors.

E-class

Specifies integrity in minutes, protects against flames and through-breeze.

A-class

Specifies integrity and heat conduction in minutes. Max temperature rise 280/330C.
A maximum of 280 on average or a maximum of 330 on a single point. A-class door contains non-combustible material.

EI Class

Specifies integrity and heat conduction in minutes. Max temeratur rise 140/180C.
A maximum of 140 on average or max 180 on a single point.

*Ei-class doors may be replaced with the corresponding A-class door, provided that it does not contain combustible material (BBR 5:6214).

Smoke density and fire resistance of the product

The fire test is carried out by the National Testing Institute (SP) where the product's fire resistance is subjected to a certain temperature influence, normally equivalent to a fire in a room. Fire resistance is one or more characteristics of the composite structure, e.g. a steel door and therefore not a feature of the materials involved. The design can then be classified in so-called fire technical classes.

Smoke and gas density Sa/Sm

Fire doors are normally classified as resistance to fire. To the fire classification, there can sometimes be a classification against smoke and gas. This is the door's ability to reduce possible leakage of smoke or gas from a fire. Smoke density of doors is designated by S and has two subclasses. So is the designation for smoke density at room temperature and Sm is designated for the density of smoke at 200 °C. These two classifications can be combined or classified separately.
