VILPE Alipai Ridge 27

The Alipai Ridge underpressure air vent can be used at the ridge of a felt roof for ventilating the roof structures and attic space. Alipai Ridge is installed on the ridge between two felt layers. Alipai Ridge is available for two different ridge pitches, 14 and 27 degrees. The pipe diameter of the 14° Alipai Ridge is 110 mm. The 27° Alipai Ridge is available in three diameters: 75, 110 and 160 mm. The Alipai Ridge includes a cowl to stop rainwater from entering the structures or attic space through the pipe. The Alipai 160 mm Ridge 27 (product no 73018) has been replaced with new VILPE® Alipai FLOW 160 ridge 27 (product no 730182). It has a new FLOW cowl and improved structure.
