Fire claddings for steel beams, timber elements and ventilation ducts in Siegen. F30, F90 and higher — approved Promatect, Knauf fire systems.
Unlike fire doors or seals, claddings don't form compartments — they stabilise load-bearing structures. The steel beam, the duct, the timber stays geometrically stable under fire for the defined duration. In Siegen, this matters most in industrial roofs where a beam collapse means a section collapse.
