KTV Classic ventilation set

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 Classic pass-through set is designed for the pass-through of standing seam roofings. The width of the Classic pass-through is 266 mm and the length 328 mm. The Classic pass-through set can be retrofitted as the pass-through of felt roofing.

There is a thick grooved rubber moulding under the flange of the Classic pass-throughs that makes the pass-through set waterproof. A seal for underlay and screws is included in the pass-through sets. Sealing compound must be used when the pass-through set is installed on a felt roof.
