Here we have gathered together an overview of all the information on building regulations, classifications and effective mechanism of fire protection glass
Building regulation requirements for fire protection.An important function of the building regulations or codes is hazard prevention in the construction sector. In Germany, building regulations are the responsibility of the federal states. The standard building regulation (MBO), on which the state building regulations are essentially all based, applies to buildings and construction products and has the following general requirements:
(Excerpt from the standard building regulation)
- §3 General Requirements (1) Installations are to be designed, installed, modified, and maintained, so that public safety and order, especially life, health and the natural fundamentals of life are not endangered.
- The following is explicitly regulated for fire protection in § 14 of the standard building regulation: § 14 Fire protection of building installations are to be designed, installed, modified and maintained, such that the break out of a fire and the spread of fire and smoke (fire spreading) is prevented and that in a fire the rescue of people and animals as well as fire fighting are as effective as possible. (...) </ Li> </ ul> The aim of fire protection is therefore to prevent the generation and spread of fire and smoke and to allow and make fire fighting easier. Fire protection glazing and fire and smoke closures are therefore of enormous importance in building fire protection. A further stipulation in § 26 of the standard building regulation (MBO) is that all components and materials are distinguished according to the requirements for their fire resistance rating.
The classification of construction types such as fire protection glazing is based on DIN EN 13501-2.
|Non-structural elements (fire protection glazing) with room closures||Class E (new to DIN EN 13501-2)|
|Non-structural elements (fire protection glazing) with room closures and insulation||Class EI (new to DIN EN 13501-2)|
|Fire protection closures (fire doors)||Class EI (new to DIN EN 13501-2)|
When using glass as a filling for light cut-outs in smoke protection doors, in general the use of single layer toughened safety glass (SWG) or laminated safety glass (LSG) is allowed, as the traffic safety, especially the fracture safety must be guaranteed.
Smoke and flame barrier separating function with reduced heat radiation. Maximum passage of radiant heat: 15 KW/m².
Only EI glazing
Smoke and flame tight room seal, compliant with the temperature limit on the unexposed side (cotton swab test). In the centre +140 K, max. 180 K.
The characteristic properties of fire resistant behaviour according to DIN EN 13501-2:
|E = Room closure||The room closure describes the ability to resist a one-sided exposure to fire such that substantial amounts of flames or hot gases do not contribute to the spread of the fire or ignite adjacent materials on the unexposed side.|
|W = reduced heat transfer||The thermal transmittance W is the ability of a component to reduce the radiant heat from one side of the component to anotherI = Thermal insulation|
|S = limitation of smoke permeability||The smoke leakage S is the ability of a component to reduce or exclude the passage of gas or smoke from one side of the component to another|
Fire resistance rating
The fire resistance rating formed and today still forms, along with other criteria, the fire resistance class of a building component. All classification units are given in minutes and indicate the length of the fire resistance rating or duration of building components. There are fire rating periods of 15 to 240 minutes, but not all units apply to all components.

The technical and building code requirements for fire protection glazing are regulated by DIN EN 1363, 1364 and 1634. These standards provide general principles for determining the fire resistance of various components that are exposed to fire under standardized conditions.
