Wie tragen Brandschutzdecken zur Einhaltung der Bauvorschriften bei?

Building codes mandate fire resistance ratings for floor-ceiling assemblies, often specifying 1-hour or 2-hour ratings to compartmentalize fire and protect occupants. Fire-rated aluminum ceilings meet these requirements by forming a continuous, tested barrier between occupied spaces and concealed plenum areas. A fully tested system includes aluminum panels with intumescent coatings, mineral wool or gypsum layers, fire-stop sealants at perimeters, and fusible suspension links—all evaluated together per ASTM E119, UL 263, or EN 13501 protocols. By installing a ceiling assembly certified to the project’s required rating, designers and contractors demonstrate compliance with code sections such as NFPA 101 Life Safety or International Building Code Chapter 7. This not only ensures occupant egress time but also facilitates approval from building officials. Proper labeling of assemblies and maintaining manufacturer-specified installation practices are essential, as deviations can void the tested rating.
