Our HS LiftUnit was named Product of the Year in 2025 by the bfb barrierefrei bauen (barrier-free building association) because it significantly simplifies the operation of lift-sliding doors, halves the effort required, and thus makes accessibility tangible in everyday life.
Easy retrofitting. Noticeably relieved. Accessible operation.
The HS LiftUnit from Gretsch-Unitas was named Product of the Year 2025 , impressively confirming what users value: a system that combines accessibility, comfort, and technical innovation – offering you greater independence and quality of life every day. Following our successes in 2019 and 2024, we are particularly pleased to receive this award again!
Noticeably lighter – even with heavy door leaves
Living spaces are increasingly equipped with generous glass surfaces, resulting in heavier lift-sliding doors and increased effort required for opening and closing. Demographic change is driving the desire for convenient and easy-to-use solutions. This is where the HS LiftUnit comes in: The maintenance-free, compact system supports the carriages when lifting door leaves weighing 100 kg and above and reduces the required torque on the handle by up to 50%. This allows you to move even large and heavy door leaves weighing up to 400 kg effortlessly – and even leaf weights of up to 600 kg can be operated safely and easily, while adhering to the maximum permissible operating forces.
Invisible technology – maximum comfort
The HS LiftUnit impresses not only with its impressive performance but also with its uncomplicated integration into existing systems.
- Conveniently retrofittable – particularly suitable for renovations and ideal for increasing sash weights due to modern glazing
- No adjustments required – sash geometry and carriage groove remain unchanged
- Widely compatible – suitable for the carriages GU-934, GU-937 and GU-937 N22
- Flexible use – suitable for all schemes and every lift-sliding sash
- Maintenance-free and durable – for long-lasting functionality without additional effort
