Rovia roof vents are intended for ventilation of vent pipes from kitchens and bathrooms, as well as for ventilation of sanitary facilities and communal sewer lines. Installation is fast and simple. Knee joint allows adjustment of roof vent onto different roof inclines (from 5° to 50°). For level roofs we offer special versions of roof vents. Rovia roof vents are available in four colors: red, dark brown, grey and black.
