The KTV roof vent can be used for ventilating roof structures and attic spaces as well as for ventilating sewer pipes. The KTV roof vent can be selected from 10 different models according to the roofing material. The selection principles are the same as for pass-through sets. A KTV roof vent contains a valve, pass-through, an underlay ring and fixing screws. It can also include an Ø 110/125 adapter, if needed. The set is also available with a flex pipe if the KTV roof vent is to be used for ventilating a sewer pipe. The Profiled steel pass-through set is designed for installing VILPE P-series 75-160 mm ventilation pipes, exhaust pipes, roof fans and aerial sleeves on all round profiled roofing (roof tile profile). The minimum length of a profiled roof tile in the metal sheet should be 350 mm. Flexible combination of rubber and plastic allows shaping and ensures a good fit on different kinds of profiled roofing. Thanks to a rubber seal mounted on the lower surface of the pass-through element the product is fully watertight. Fixing screws, sealing compound and an underlay ring are included.
