Ventilating firestop
The invention relates to a ventilating firestop (10), comprising a load-bearing mesh(12) fitted with an intumescent (14), wherein the mesh (12) is malleable to a completely or partially confined volume (22), and the intumescent (14) applied to the mesh (12) forms a stripe pattern of intumescent spaced apart and with ventilating openings (30) between the stripes. At least the intumescent (14) in a plane which is exposed by fire forms a fine mesh and rapidly expandable stripe pattern which, during the fire attack phase, seals the openings (30) and forms a fire-insulating shield (40), and the intumescent (14) located separately from the shield (40), after formation of the shield (40), is expandable to subsequently fills up the remaining volume (22) in the firestop (10).
