The quality requirements for ventilation sashes are particularly high for those installed in the roof. WICTEC 50 meets these requirements and delivers a delicate appearance with minimal off-set of the external glass level. Reduced profile widths, concealed hinges with 90º opening angle and the option of large sash formats, offer extensive freedom of design. Thanks to the large ventilation cross sectional areas, the WICTEC 50 skylight is also ideal for use as natural smoke and heat exhaust ventilators.
