Application:
The WSG-H3 flat roof weather-proof louvre offers a visually more attractive alternative as a rain protector or a  protector hood. They act as the horizontal duct closure for fitting on the outside of buildings or as ventilation opening closures on roofs. The WSG-H3 can be integrated into the roof constructions and the colour matched so that it remains inconspicuous and blends in perfectly to its surroundings. Any roof pitch can be fitted with our grids in an aesthetically attractive and optimal manner.

Function:
Precipitation is deflected by the blades and drained to the surrounding water channel. Water is drained out of the channel by one or several discharge nozzles and routed into a customer supplied drain pipe. On the bottom flange variant (Fu), the surrounding water channel at the bottom edge of the grid is open to the outside so that water can flow over the roof. An overhead mesh grating prevents large dirt particles from entering. The horizontal weather-proof louvre is available as H3 with three blade rows for supply and exhaust air.
