Well designed and long-lasting: the basics

Even the standard components are impressive owing to a well thought out design and construction which ensures problem-free functionality of all Lift&Slide components which normally lasts the entire lifetime of the Lift & Slide element. Users enjoy exceptional ease of movement and running smoothness of the sliding elements, straightforward operation when opening and closing and sophisticated barrier-free thresholds.

Tested security for maximum burglar inhibition

Thanks to the burglar-inhibiting design of its many hardware components, Gretsch-Unitas gives its customers greater peace of mind, because they know they are effectively protected against manipulation attempts.

The PVC systems are tested at least to DIN EN 1627-1630 RC 2, and the timber hardware is also tested up to RC 3. With Gretsch-Unitas, every element can essentially be designed to satisfy the stringent requirements of resistance class RC 3. In addition, all Gretsch-Unitas Lift&Slide hardware is certified for retrofitting according to DIN 18104-2.

We provide assistance with planning and design.

Secure and convenient ventilation

Night ventilation for Lift&Slide doors: open but still securely locked

With the night ventilation for Lift&Slide doors, Gretsch-Unitas has successfully developed an innovative solution, as the RC 2-tested night ventilation allows the sliding sash to be put in the ventilation position but also provides effective burglar resistance by locking the sliding sash securely to the frame in this position.
