The RENSON® Oxyvent® is a thermally broken extraction ventilator for fast and easy installation on glass, polycarbonate panels or sandwich panels assembled in a sloping conservatory roof. The perforated (2 series: 2.9 x 19 mm and 2.9 x 14 mm) interior profile acts as an insect mesh. The external profile also acts as a rain cap. Thanks to natural convection, cool and fresh air is supplied through vents in the vertical glass wall, while warm and humid air is extracted through the Oxyvent®.
