Product of the Year 2025

Our HS LiftUnit was named Product of the Year in 2025 by bfb barrierefrei bauen, as it significantly facilitates the operation of lift and slide doors, halves the required force, and thus makes accessibility noticeably easier in everyday life.

Simple retrofitting. Noticeably relief. Barrier-free operation.
The HS LiftUnit from Gretsch-Unitas has been chosen as the Product of the Year 2025, impressively confirming what users appreciate: a system that combines accessibility, comfort, and technical innovation – offering you more independence and quality of life every day. Following the successes in 2019 and 2024, we are especially pleased about this repeated award!

Noticeably easier – also with heavy sashes

Living spaces are increasingly equipped with large glazing panels, resulting in heavier Lift&Slide doors and increased effort required for opening and closing. Especially in light of demographic changes, the demand for comfortable and easy-to-operate solutions is growing. This is where the HS LiftUnit comes in: the maintenance-free, compact system supports the bogies when lifting sashes from 100 kg and reduces the required torque on the handle by up to 50%. This means you can effortlessly move even large and heavy sashes weighing up to 400 kg – and even sashes weighing up to 600 kg can be safely and easily operated at a force which is within the maximum permissible limit.

Invisible technology – maximum comfort

The HS LiftUnit impresses not only with its outstanding performance, but also with its straightforward integration into existing systems:

Comfortably retrofittable – especially suitable for renovations and ideal for increasing sash weights due to modern glazing
No adjustments required – sash geometry and bogie groove remain unchanged
Widely compatible – suitable for GU-934, GU-937, and GU-937 N22 bogies
Flexible application – suitable for all patterns and any Lift&Slide sash
Maintenance-free and durable – for long-lasting functionality without additional effort
