Double-walled insulated ventilation with bituminous roofing slab (composite-reinforced SBS), specifically developed for the renovation of flat roofs. The perfectly round cap prevents any condensation from entering the ventilation system. The conical sealing ring ensures an airtight connection. The ventilation must be placed between the bottom layer and the top layer by flame-torching it on the bituminous bottom layer using a light flame.
Available diameters : 110/125 – 150/160
