Load-bearing structures keep their fire-resistance rating through approved board claddings, fire-protective coatings or mineral-wool build-ups — installed in Dahlem and Region Regierungsbezirk Köln.
Fire claddings are mineral-wool systems that protect ventilation ducts from heating for 30 to 120 minutes. The cladding turns an unprotected steel beam into an properly rated structural element.
