LAMILUX Glass Roof Fire Resistance F30/REI30, REI60

Glass Roof Fire Resistance combines safety and appearance


If a fire breaks out, it can have dire consequences for people, animals and property. The violence of fire must never be underestimated. Because in the worst case, entire industrial or residential areas can burn down, endangering human lives. That is why it is particularly important to choose the right windows when constructing or renovating a building. Fire-resistant windows with heat- and fire-resistant glazing are the optimal helpers and thus become real lifesavers. When it comes to fire protection and fire protection windows, we at LAMILUX are there for you and will be happy to advise you on the advantages of our Glass Roof Fire Resistance.

Strong protection in case of fire

Through LAMILUX fire-resistant windows


The demands and requirements placed on windows are many and varied and are increasing as fire protection requirements continue to rise. In addition to thermal insulation or soundproofing, fire protection is at the top of the list of requirements for a window. Structural fire protection and the associated building laws and requirements are laid down in the respective state building codes. If you install a window in a fire-resistant roof in your building, you must use a window with fire-resistant glazing for it. When a fire-resistant window is mandatory is regulated in the building codes or the responsible building authorities prescribe fire-resistant windows for special building measures.

Fire-resistant windows withstand fire and heat

A fire-resistant window is a window that withstands fire and heat for a certain period of time in the event of a fire. The time specification for how long the fire-resistant window must withstand the fire and heat is recorded in the requirements for the window. During this time, the component must provide sufficient protection in case of fire. The fire-resistant window receives this protection through special layers in the glass panes. 

Fire protection glass roofs cannot be opened. Windows with fire-resistant glazing are mainly used in larger public buildings where many people are present, such as educational institutions, cultural facilities or shopping centres, among others. There, the fire-resistant window forms fire barriers and prevents flames from spreading to other buildings or parts of buildings while keeping escape and rescue routes clear.

Glass Roof Fire Resistance

The LAMILUX Glass Roof Fire Resistance offers strong protection in case of fire. Our LAMILUX Glass Roof Fire Resistance is available in three different versions. The Glass Roof Fire Resistance F30/REI30 withstands fire and heat for at least 30 minutes, the new product variant Glass Roof Fire Resistance REI60 even 60 minutes. We will be happy to provide you with comprehensive and competent advice on our products and how you can integrate all the requirements relating to fire protection safety into your building project.

Reliable partner in fire protection by LAMILUX Service 

When using fire-resistant windows in a building project, it is absolutely necessary that the fire-resistant windows are installed professionally. Therefore, only certified specialist companies should be used for the installation. In most cases, the building authority requires a declaration from the installing company regarding the professional installation of the fire-resistant windows. This is because there are many different requirements to be met when installing fire-resistant glazing so that the fire-resistant windows are fully functional and save lives in the event of a fire. That's why you trust the experience and service of fire protection specialists. We are your reliable partner for fire-resistant windows.

The fire resistance classes

Glass Roof Fire Resistance F30/REI30, REI60


If you are considering buying a fire-resistant window for your building project, you should strongly consider that the products comply with a tested standard. At LAMILUX, the fire-resistant windows comply with the German or European standard, depending on the variant. These standards test the behaviour of the glass in the event of a fire. Components are divided into different fire resistance classes according to their fire resistance duration. In Germany, this classification is regulated by the German standard DIN 4102-2 and the European standard EN 13501-2.

Difference between fire resistance classes

Marking F according to DIN EN 4102-2

DIN 4102-2 identifies the fire resistance class with the code letter F and a number. The number indicates the minutes determined in the tests for the fire resistance duration. This value is rounded down to the nearest value divisible by 30, resulting in the fire resistance classes F30, F60, F90.  

Marking REI according to EN 13501-2

The EN 13501-2 standard differentiates the following criteria for describing fire resistance: Load-bearing capacity (R), room-enclosing function (E) and thermal insulation (I). For a glass roof, the performance time in minutes of one of the following numbers is given for each criterion: 15, 20, 30, 45, 60, 90, 120, 180, 240. The European standard therefore has a more precise classification than DIN 4102.

Fire resistance class of Glass Roof Fire Resistance

For two years now, with our Glass Roof Fire Resistance F30/REI30, you have been able to obtain a fire-resistant window that is certified according to both German and European standards. Its fire resistance, load-bearing capacity, room-enclosing function and thermal insulation are maintained for 30 minutes. With the new Glass Roof Fire Resistance REI60, we have succeeded in extending this protection even further: For at least 60 minutes, the Glass Roof Fire Resistance REI60 withstands fire and heat and prevents flames from spreading to other parts of the building in the event of a fire.
