Fire-rated glazing systems are used where buildings must limit the spread of fire and smoke between defined compartments, while maintaining visibility and natural light.
Unlike standard glazing systems, these solutions are specified based on safety requirements, building design, and regulatory compliance — not appearance or general performance.
Fire-rated windows and glass doors are typically used in areas where safe evacuation and compartmentation are essential.
Common applications include:
Shared corridors in residential buildings
Stairwells used as vertical escape routes
Protected escape paths leading to exits
Separation between fire compartments
Specific façade areas where fire resistance is required
In these situations, systems are designed to help ensure that escape routes remain usable for a defined period during a fire.
Fire classifications such as EI30, EI60, EI90, and EI120 describe how a system performs under standardised fire testing.
E (Integrity) — prevents flames and hot gases from passing through
I (Insulation) — limits temperature rise on the non-fire side
The number refers to the duration, in minutes, that the system maintains these properties under test conditions.
Fire-rated performance depends on the complete tested system — not a single component.
Profiles, glazing, seals, hardware, and installation method all form part of the certified configuration. Any variation can affect performance.
For this reason, fire-rated systems must always be selected based on tested and documented assemblies.
Modern fire-rated glazing systems allow clear sightlines and natural light in shared spaces such as corridors and stairwells.
This makes it possible to improve safety while maintaining usable, well-lit environments.

Selecting a fire-rated system depends on:
Building type and evacuation strategy
Required EI classification
Area of application (corridor, stairwell, façade)
Coordination with project documentation
These systems are typically specified as part of a coordinated building design process.
All systems are CE Marked and tested to EN 1634-1 and EN 1363-1 European fire testing standards.
To understand how these systems are configured, view technical specifications, and explore available fire-rated solutions:
No. Fire-rated glazing is not required in all residential buildings, particularly in single-family homes.
It is typically mandatory in:
– Multi-family residential buildings
– Buildings with shared escape routes
– Developments where compartmentation is required by regulation
Requirements depend on building height, occupancy, and applicable fire safety regulations. These are usually defined during the design phase.
Yes. Fire-rated systems can be used in façades where fire resistance is required between buildings or across elevation zones.
Typical façade applications include:
– Buildings located close to property boundaries
– Urban developments with risk of fire spread between structures
– Façade sections aligned with escape routes
These applications require specific tested systems.

Yes — when the system includes both integrity and insulation performance.
– Integrity (E) prevents flames and hot gases
– Insulation (I) limits heat transfer
This distinction is important, as heat alone can ignite nearby materials. Most regulations require EI-rated systems.
Any modification can invalidate the system’s certification.
This includes:
– Changing hardware
– Adjusting dimensions
– Using non-approved components
– Altering installation methods
Fire-rated systems must be installed exactly as tested to ensure performance.
Yes. Although visually similar, they differ significantly in construction and purpose.
They include:
– Fire-resistant glazing
– Tested profile systems
– Certified seals and hardware
– Strict installation requirements
They are designed for life safety, not just general performance.
Under normal use, fire-rated systems can last for decades.
However, their fire performance depends on:
– Proper installation
– Regular maintenance
– Integrity of components
Routine inspections may be required to maintain compliance.
Responsibility is shared across the project team:
– Architects define requirements
– Fire safety consultants validate compliance
– Contractors ensure correct installation
– Building owners maintain systems over time
Proper documentation and certified systems are essential.
Yes. Modern systems allow safety requirements to be met without compromising design.
They enable:
– Natural light in escape routes
– Visual openness between spaces
– More comfortable shared environments
This is especially valuable in residential buildings where traditional fire separation created enclosed, darker spaces.
