The trapeze ventilation ceiling is the optimum fresh air system in large-scale stable buildings. The slotted panels comprise resistant GRP, which is combined with a specially developed and treated mineral wool. This consists of 2 layers and is laminated on the underside with a water-repellent fleece. The fresh air, which flows in via the roof space, is heated and distributed evenly across the entire stable ceiling. At the same time this system acts as economical ceiling insulation. The trapeze ventilation ceiling is optimally supplemented with ceiling fresh air inlets for summer air flow rates.
