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