EI30, EI60, EI90 — the EU classification used in parallel with DIN 4102-5.
A fire door is a DIN 4102-5 classified fire-resisting closure. It protects escape routes for a defined duration — 30, 60 or 90 minutes (T30, T60, T90 in German classification, EI30/EI60/EI90 by European norm). Every door we install in Raesfeld carries an approval number and a declaration of conformity that the building authority can verify.
