Fire-resistant air ducts
Fire-resistant air ducts that are assembled on site from CE-marked fire protective boards covered by a European Technical Assessment (ETA) issued on the basis of a European Assessment Document (EAD) and the related accessories are used as part of ventilation systems in buildings.
Fire-resistant air ducts prevent the spread of fire across separating elements for the verified duration.
Regulatory framework
DIBt grants general construction technique permits (aBG) for fire-resistant air ducts in cases where the ETA does not cover a complete kit consisting of fire protective boards and the associated seals, fittings, connections and fasteners.
MVVTB 2020/1, Annex 14, Section 6.3.3
