Les plafonds en treillis métallique peuvent-ils être utilisés dans les systèmes de plafond coupe-feu ?

Yes—properly engineered metal mesh ceilings can be part of a fire-rated ceiling assembly. Aluminum mesh has a high melting point and does not emit toxic smoke, making it compatible with many fire-rated systems. At PRANCE, we collaborate with fire-protection specialists to ensure that mesh panels meet local building codes such as ASTM E119 and EN 13501.

Integration typically involves installing mesh panels beneath a rated barrier—like gypsum board or mineral fiber tiles—supported by a fire-resistant suspension grid. In some applications, we offer fire-rated hangers and draft stops that prevent flame spread through plenum spaces. Recessed sprinklers and detectors remain fully accessible through the open weave.

Testing and certification are essential. We validate assemblies in third-party fire laboratories to confirm integrity under exposure. The result is a visually open metal mesh ceiling that preserves natural ventilation and lighting while delivering the required fire performance. This approach is ideal for feature ceilings in atriums, stairwells, and commercial lobbies where both aesthetics and safety are paramount.
