What is Fire-Resistant Joinery?

Fire-resistant joinery refers to doors, windows, and walls designed to resist fire and prevent its spread. These elements are made from materials like aluminum, steel, or fire-treated wood, and are tested to meet specific fire resistance standards such as EI30 or EI60.

Understanding EI Ratings: EI₁ vs. EI₂

The EI rating of a fire-resistant element defines its ability to maintain structural integrity and provide thermal insulation during a fire:

• E (Integrity): Prevents the passage of flames and hot gases.
• I (Insulation): Limits heat transfer to the unexposed side of the element.

Within the European classification system (EN 13501-2), the insulation criterion is further divided into EI₁ and EI₂, based on stricter or more flexible testing conditions:

• EI₁: Involves stricter criteria, particularly in the positioning of thermocouples and the maximum allowed temperature rise. This rating is typically required in sensitive environments such as residential buildings, public access areas, escape routes, and healthcare facilities.
• EI₂: Allows more tolerance in thermocouple placement and temperature limits, making it suitable for industrial, commercial, and less critical applications.

Belgian Context

While EI₁ and EI₂ are both part of the European standard, Belgium applies EI₁ more rigorously than many other countries. In Belgian regulations, EI₁ is often explicitly required for internal fire doors and compartmentation in residential or public buildings. Other countries may allow EI₂ in scenarios where Belgium mandates EI₁.

Why Choose Aluminium Fire Joinery?

Aluminium offers excellent dimensional stability, corrosion resistance, and fire protection when properly treated and glazed. It is ideal for architectural applications where aesthetics and safety must be combined.
