Rules for installation, anchoring, sealing — binding and inspection-relevant in Kalletal.
A fire door is a tested 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 Kalletal carries an approval number and a declaration of conformity that the building authority can verify.
