MasterLine 8 Hidden Vent is a development of the well-established MasterLine 8 system, in which the sash profile is covered by the outer frame. This gives the window the appearance of a fixed element, making it possible to create minimalist, uniform facades.

The Hidden Vent option employs Sobinco tilt-and-turn hardware allowing easy ventilation of rooms while maintaining the aesthetics of fixed solutions.
