HIRT kinetics® HF


HIRT kinetics® HF saves space and delivers a more elegant and practical solution than casement windows. When retracted, the large open space allows for much more air and light to enter the room than with a conventional window. Moreover, the vertical opening mechanism allows you to make full use of the available space.


We built on the known advantages of vertical sliding mechanisms by adding new features made possible by modern technology. Current structural engineering regulations with regard to sound and heat insulation are met, and living comfort is guaranteed. The slim profiles of the sash and the frame, with integrated mechanics please even the most demanding design enthusiasts.


HIRT kinetics® HF is a patented lifting and descending window system that has been successfully installed for years. What makes this system so attractive is that the window panel can vertically slide behind a fixed panel, offering a lot of freedom in terms of its design and use. Furthermore, this system allows for efficient room ventilation and provides superior thermal insulation, which contributes to lower energy consumption.

HIRT kinetics® HF is becoming increasingly popular in a wide range of buildings. Schools, restaurants, offices and private home owners enjoy full use of their space and freedoms that casement windows lack thanks to the vertical opening principle of the HF solution.


Panels up to a maximum width of 13 ft and height of 8 ft (max. 64 sq ft) with a mass of approx. 660 lb are possible with the standard version. Larger dimensions necessitate modifications to panels, runners, suspensions, etc. Custom solutions are possible, pending engineering review.



The window panel is suspended from counterweights by means of chains. The high-quality ball bearings move in the guide slot in perfect silence. The runners with integrated mechanical components are mounted on the frame profile and directly connect to the panel to save space. This allows for an extremely slim profile. The classy aluminum cladding conceals the mechanics, suspension and counterweights.

There are no limits in size, shapes and weight.
Everything is possible. We realise your dreams.
