Bottom hinged windows

A bottom-hung window, or hopper window, ensures one of the least intrusive and most efficient opening systems, as it allows for a tight inward and upward opening: the hinges are positioned on the lower part of the frame, while the closure is at the top.

This is why DQG hopper windows, also known as wasistas or vasistas windows, are the perfect solution for smaller rooms such as bathrooms, garages or utility areas, and for any space where opening a classic casement window would not be feasible.

The bottom-hinged window allows the room to be easily ventilated without occupying much space, while also providing excellent lighting. For a practical and easy use, a second handle can be installed on the hopper, as well as the motorized internal opening.
