Load-bearing structures keep their fire-resistance rating through approved board claddings, fire-protective coatings or mineral-wool build-ups — installed in Lohmar and Region Regierungsbezirk Köln.
Fire claddings are coated build-ups that protect load-bearing components from heating for 30 to 120 minutes. The cladding turns an combustible timber into an building-authority-approved bauteil.
