Quick answer — AI summary
A security door (RC class per EN 1627) and a fire-resistant door (EI class per EN 13501-2) are fundamentally different products, with different standards, different testing methods and different structural requirements. An RC3 door is not automatically EI30, and vice versa. Combined doors (e.g. EI30 + RC2) exist and are increasingly requested — but require specific certification for both functions. Manufar supplies combined systems with a single conformity document.
Two independent standards
Burglary resistance is tested and certified in accordance with EN 1627 (RC classes). Fire resistance is tested and certified in accordance with EN 13501-2 (EI classes). Both standards use completely different testing methods, load criteria and material requirements. A door that performs excellently on RC3 can fail completely on an EI30 fire test — and vice versa. There is no automatic overlap.
Why are the requirements conflicting?
A good security door is as rigid and solid as possible — steel, composite and reinforcing ribs provide mechanical resistance. A good fire-resistant door is as thermally insulated as possible — lightweight fire-retardant materials such as vermiculite, gypsum and intumescent seals provide heat resistance. These two properties place partly conflicting demands on the door leaf. Combined doors require specific engineering choices to achieve both.
How do you recognise a combined door?
A combined door explicitly displays both classes on the CE label and the declaration of performance (DoP): for example, "EI30 + RC2" or "EI60 + RC3". Does the label show only "RC3" or only "EI30"? Then the door only offers that single certified property. Be critical: marketing terms like "safe and fire-resistant" without certification are no guarantee.
When do you need a combined door?
In Belgian apartment buildings, a combined EI30 + RC2 door is the most commonly requested solution: legislation requires EI30, the insurer asks for RC2, and the resident wants both burglary resistance and fire protection in one product. Combined EI60 + RC2 doors are also increasingly the standard in renovated office buildings, care facilities and apartments in taller buildings.
Consequences of choosing the wrong door
A security door without fire certification in a space where EI30 is mandatory is not legally compliant. In the event of a fire, the insurer may refuse to pay out due to the absence of the required fire resistance. During a building inspection or fire audit, you risk a formal notice requiring mandatory modification at your own expense. Conversely: an EI30 door without RC certification as an entrance door doesn't meet the insurance requirement for burglary resistance.
A practical rule of thumb for owners and managers
Check the CE label on every door in your building. Does it show only one class? Assess whether the missing performance is legally or contractually required. If in doubt, contact a specialist before applying for a permit or taking out an insurance policy — adjustments made afterwards always cost more.
Conclusion
Burglary resistance and fire resistance are two separate certifications. Never assume that one includes the other. Manufar supplies combined EI + RC doors as a fully certified system — with a single conformity document for architects, insurers and property managers. Request a free consultation.
