HIRT kinetics® SF 90

HIRT kinetics® SF 90

HIRT kinetics® has been upgrading private homes and commercial buildings across the globe for many years. Our large descending windows can withstand extreme climatic conditions and have a proven track record of operation even in highly challenging environments.


HIRT kinetics® solutions are not suspended. Instead, they rest on a supporting structure that is linked to a counterweight. The system is perfectly balanced, which allows for the system to move effortlessly and silently with the use of a small motor.


The “small” model, HIRT kinetics® SF 90, supports a max. width of 6 m/19.5 ft and a max. height of 6 m/19.5 ft. The maximum size is 18 m2/200 sqf and the maximum weight of the movable element is 1500 kg/3,300 lb.


The maximum glass thickness for HIRT kinetics® SF 90 is 63 mm/2.5 in. Triple insulating glass, double insulating glass or single-pane glass can be installed. Special glass, such as bullet-proof safety glass, can also be installed as an option.


This threshold allows for safety, comfort and modern design. Groove-milled stainless steel is a real eye-catcher. It is completely level and free of protrusions, providing full accessibility on foot or wheels that can withstand high loads. Customized designs using other materials such as wood, stone or other flooring materials are also possible. In this way, the threshold can become virtually invisible.
