Fire-Rated Glazing in Luxembourg — EI30 to EI120, Installation and CE Certificates
Fire-rated glazing is a structural part of fire safety: it compartments a building, slows the spread of flame and smoke, and buys the occupants time to get out. Vitralux supplies and installs certified fire-rated glazing in every classification across Luxembourg, from glass doors to compartment walls, from internal subdivisions to façades. CE certificates come with every job.

Compartment, slow down, protect
Fire-rated glazing is a structural part of fire safety: it compartments a building, slows the spread of flame and smoke, and buys the occupants time to get out. Vitralux supplies and installs certified fire-rated glazing in every classification across Luxembourg, from glass doors to compartment walls, from internal subdivisions to façades. CE certificates come with every job.

Careful: without certification there is no classification
Fire-rated glazing that is uncertified or badly installed voids the fire rating of the whole assembly. Vitralux stands behind the compliance of every installation and supplies the CE certificates you need for the fire strategy and for regulatory inspections.

Which fire ratings does Vitralux cover?
The EI classification defines how long a piece of glazing resists fire while maintaining its integrity (E) and its insulation (I). The higher the number, the longer the protection. Vitralux covers every classification from EI30 through EI60 and EI90 to EI120.
| Classification | Fire resistance | Typical applications | Regulatory context |
|---|---|---|---|
| EI 30 | 30 minutes | Internal doors, office partitions, subdivisions | Low to moderate risk buildings, blocks of flats |
| EI 60 | 60 minutes | Compartmentation in public buildings, fire walls, flat entrance doors | Larger public buildings, high-rise blocks |
| EI 90 | 90 minutes | Load-bearing structures, walk-on glass floors, fire-rated façades | High-rise buildings, major public buildings, industrial premises |
| EI 120 | 120 minutes | High-demand compartmentation, sensitive buildings | Major assembly buildings, high-risk industrial sites |

For complex projects or buildings under specific regulations (high-rise, major assembly buildings, high-risk industrial sites), Vitralux can prepare a technical study with an external fire engineering consultancy. For walk-on fire-rated floors, see our fire-rated structural glass floors ; for fire-rated glazing in a façade, see our glass façades page.

What Vitralux guarantees on your fire-rated glazing
Fire-rated glazing is a field where safety comes before everything else. Glass that is wrongly chosen, wrongly sized or wrongly installed voids the whole fire compartment — with potentially serious legal and human consequences. Vitralux gives you the assurance you need at every stage of the project.
CE certificates supplied
Every piece of fire-rated glazing supplied and installed by Vitralux comes with its CE certificates of conformity. They are essential for the fire strategy, for regulatory inspections and for your insurers.
Every classification covered
EI30, EI60, EI90, EI120: Vitralux selects the certified glass that matches your regulatory classification and the situation in your building.

Frequently asked questions about fire-rated glazing
Class E glazing holds back flame and smoke but gives no protection against radiant heat: people and materials on the other side can still be affected by the thermal radiation. Class EI glazing adds insulation: it limits heat transfer and actively protects the occupants. For the great majority of applications (corridor doors, partitions, subdivisions), EI is what the regulations require.
Yes, and it is one of the jobs Vitralux does most often. When the glass in a fire door is cracked, broken or failing, the glass alone can be replaced in the existing frame — the whole door does not have to go. The new glass must match or exceed the classification of the original. Vitralux checks the compatibility and supplies the matching CE certificate.
Yes. Modern fire-rated glass (borosilicate glass, special laminated glass) comes very close to ordinary glass to look through. The optical quality is excellent and does not get in the way of the view. Some products can also be satin-finished or screen printed while keeping their fire rating.
Fire-rated glazing that is properly installed and looked after has no theoretical service life. It does have to be replaced, however, as soon as it shows a crack, a chip, delamination or any visible damage. Even an apparently minor crack can compromise the fire rating of the whole assembly. The periodic inspections required in public buildings are what usually pick these up.
Absolutely. Vitralux works for every type of client: private individuals (replacing the glass in a flat entrance door, bringing a home up to standard), managing agents, building managers, businesses, public buildings and institutions.
