Modern Sliding Solutions from Roto

Large sliding windows and doors are popular worldwide because of their space-saving design. As an internationally recognized supplier of premium hardware systems for sliding elements, Roto Frank Window and Door Technology demonstrated at BAU 2025 the significant improvements in operating convenience and user safety that can be achieved by choosing the right hardware.

In just a few years, the smart, tightly sealed Roto Patio Inowa parallel sliding hardware has become one of Roto’s most successful systems worldwide. The Roto Patio Inowa | Max version is suitable for small to large sliding elements of all frame materials. A ball bearing and height adjustable roller unit with integrated brushes and a comfort cam ensures smooth running and ease of use.

Inowa’s additional Soft functions provide extra comfort. SoftClose and SoftOpen, for sash weights up to 440 lbs. (200 kg), can be combined to gently brake the sash just before pulling it into the locked or open position. This allows users to operate even a heavy sash with ease.

Roto recommends integrating the SoftStop function at sash weights above 440 lbs. (200 kg) to help ensure damped sliding of the sash. This function also brakes the door, but does not automatically close it.

Roto Patio Lift hardware impresses with its exceptionally smooth running and ease of use, even in weight classes up to 880 lbs. (400 kg). Versions of the Lift&Slide system are available for many standard and slim aluminum and vinyl profiles. These sliding elements can also be equipped with MVS contact sensors for electronic monitoring. In addition, a locking pin for night ventilation makes it possible to ventilate the room without drafts. Dampers are integrated into the espagnolette, even in the standard version, to prevent handle rebound and provide greater safety when operating sashes weighing more than 661 lbs. (300 kg).

Using the GL-SV glazing block from the Roto Glas-Tec range for glazing large sliding elements is also recommended. With its reinforced profile leg system, it boasts a high load-bearing capacity for heavy insulating glass. Featuring a ventilation channel for constant rebate area ventilation and vapor pressure compensation, it can be used to produce high-quality and durable elements. Together with the Roto sliding system, Roto Glas-Tec glazing blocks create an ideal solution for seamless and efficient sliding operations.
