Fire claddings for steel beams, timber elements and ventilation ducts in Marl. F30, F90 and higher — approved Promatect, Knauf fire systems.
System selection in Marl depends on the bauteil and the visibility. Conservation-grade structures often get intumescent coatings — they meet F-rating without altering geometry. Hidden beams use Knauf gypsum-fire systems for cost and speed.
