With this type of ventilation, a vertical surface is moved up or down as required by precise control mechanisms. The lifting or closing process can be carried out using various types of drive. An electric or manual shaft drive is available for the movement of the lifting window system. The shaft drive, together with the cable drum, ensures that the windows are raised and lowered evenly.

The lifting window is an ideal ventilation system for isolated building areas that require a closing function and sufficient light in addition to generous ventilation options. Lifting windows are suitable for all housing systems in stable construction. The lifting windows are often made of UV-stable, translucent plastic/double-wall panels. The opening technology offers the option of a pull rope and pulley or a drive tube with rope drums.

What do the different types of lifting windows have in common?

They are driven by Lock products. Whether single windows, continuous windows or double-lift windows - a selection can be made as required and moved using Lock drive systems.

Natural ventilation is created by temperature differences inside and outside the building as well as by wind movements. Optimal use of natural ventilation is made possible by orienting the building perpendicular to the main wind direction. In addition, the continuous adjustment of the window openings allows manual or automatic regulation of the room climate according to the season or weather.
