Rules for installation, anchoring, sealing — binding and inspection-relevant in Zülpich.
A fire door is a building-authority-approved fire-resisting closure. It holds back flames and smoke 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 Zülpich carries an approval number and a declaration of conformity that the consultant can verify.
