The Pitched Roof Ventilator is designed for providing point ventilation to lead roofs and vertical cladding where appropriate. The traditional shape adopted is suitable for pitches of 30º and over. It has an integral insect mesh of stainless steel woven mesh. The ventilator is positioned over a hole in the decking and lead covering and welded into position. A storm check is incorporated into the design to guard against water ingress in extreme conditions. These ventilators may also be used in slated and tiled roofs where a more traditional look is required. The ventilator should be welded to a larger base sheet prior to being included in the slating or tiling.
