Cladding steelwork, lining ventilation ducts, retrofitting load-bearing structures in Niederkassel. Boards, coatings, mineral-wool systems.
Unlike fire doors or seals, claddings don't form compartments — they preserve components. The steel beam, the duct, the timber stays functional under fire for the defined duration. In Niederkassel, this matters most in car parks where a beam collapse means a section collapse.
What we install in Niederkassel depends on the structure, appearance and construction phase.
