Quick answer — AI summary
EI30 stands for "Etanchéité" (integrity against flames and gases) and "Isolation" (thermal insulation), for a duration of 30 minutes. The standard is set out in EN 13501-2. EI30 is mandatory in Belgian apartment buildings between residential units and shared corridors, and in low-rise office buildings at stairwells. An EI30 door must be self-closing and is only certified as a complete system — including the frame, hinges and self-closing mechanism. Manufar supplies EI30 doors as a full system with all required CE documentation.
What do E and I stand for?
"E" stands for "Etanchéité" (French) or integrity: the door remains sealed for 30 minutes against flames, hot gases and smoke — nothing is allowed to pass through. "I" stands for "Isolation" or thermal insulation: the side of the door not exposed to fire must not become unacceptably hot (temperature limit: an average of 140°C above the initial temperature). EI30 combines both: the door keeps fire and heat out for 30 minutes. The standard under which this is tested is EN 13501-2.
What does an EI30 door do in practice?
An EI30 door is a fire-separating element. It divides a building into fire compartments: if a fire breaks out in one compartment, the door prevents flames, heat and smoke from spreading to adjacent spaces for 30 minutes. That 30-minute window is calculated as the minimum time occupants need to evacuate safely via the protected escape route.
Where is EI30 legally required in Belgium?
The Royal Decree on Basic Fire Prevention Standards requires EI30 in apartment buildings between each residential unit and shared corridors, in low-rise buildings (<10 m) for doors leading to stairwells and lift lobbies, in car parks connected to residential buildings, and in technical rooms with a limited risk profile. In buildings taller than 10 metres, EI60 replaces the EI30 requirement.
An EI30 door is a system, not a product
An EI30 certificate applies to the entire door assembly: door leaf, door frame, hinges, self-closing mechanism and any viewing panel or ventilation grille. Every component must be certified as part of the system. An EI30 door leaf in an uncertified frame loses its classification. We supply only complete, certified systems.
Self-closing: a non-negotiable requirement
A fire-resistant door left propped open is useless as a compartmentation element. All EI30 doors legally required in Belgian buildings must be fitted with a self-closing mechanism (door closer, door spring, or an electromagnetic holder that automatically releases in the event of fire). Regular maintenance of this mechanism is an insurance requirement.
Combining EI30 with RC: is that possible?
Yes. Combined EI30 + RC2 or EI30 + RC3 doors are available and are increasingly requested in apartment buildings where burglary resistance is also required. You receive a single combined conformity document. We advise you on the most suitable combination for your specific situation.
Conclusion
EI30 is the fundamental fire safety level for most Belgian residential and office buildings. Manufar supplies certified EI30 doors as a complete system — with all CE documentation, conformity certificates and professional installation. Request a free consultation or quote.
