The Harcon plain tile vents are an extremely neat and compact design to match the standard 265mm x 165mm plain tile. They are installed simply, replacing only 3 tiles, without the need to cut any roof battens or surrounding tiles, making them ideal for all new build and refurbishment applications. They incorporate a felt sleeve which fits neatly between the battens. Features Careful design ensures the plain tile roofline vent is virtually invisible from the ground. A box below the vent collects any water that enters it and ducts it back onto the roof. Rectangular outlet designed to fit between standard plain tile battens with a factory fitted neat felt sleeve.
