Zusammenfassung:	The ventilator 10 comprises an elongate extruded strip 11 of unplasticised PVC with ventilating openings 19 punched through it and covered with fly-screen mesh 20. Strip 11 is fixed to a fascia board 7 along one edge by a fixing strip 14. Along its opposite edge, strip 11 has a channel-shaped part 13 for receiving and supporting one edge of a soffit board 8. To facilitate the insertion of the edge of soffit board 8 into channel-shaped part 13 and to enable part 13 to grip soffit boards of varying thicknesses, strip 11 is co-extruded with a portion 24 of plasticised PVC which acts as a hinge to enable the sides 21, 23 of the channel-shaped part 13 to be moved more easily away from each other, but to remain springy.
