Tilt&Turn Hardware Technology for Aluminum Systems

The demand for Tilt&Turn aluminum windows is growing internationally. With its Roto AL and Roto AL Designo Tilt&Turn hardware product ranges, Roto Window and Door Technology offers manufacturers reliable yet innovative hardware solutions.

For years, manufacturers have used the Roto AL Designo concealed hinge side to produce Tilt&Turn windows in a wide variety of formats. Roto is now launching a version for window sashes up to 176 lbs. (80 kg) with a possible opening angle of up to 180°, making it simpler to ventilate and clean. The AL Designo | STS 180° hinge side can be combined with flush profile systems on request and has 304 SST components for superior corrosion-resistance. The optimized AL Designo | STS enables the window sash to be opened with minimal clearance, offering greater design freedom for 14 mm groove frame profiles.

Increasing market standards demand aluminum windows with tested opening restrictors to enhance frame protection and mitigate potential risks both inside and outside buildings when windows are fully open. At BAU 2025, Roto showcased a new Turn Only retaining restrictor directly controlled by the handle for exceptional operating convenience. This restrictor can be retrofitted and its retaining force adjusted when installed. Users can lock the window sash in any position using the handle.

The AL | ELA opening restrictor with end position locking is one of the most successful solutions from Roto’s accessories. It ensures that sashes open to a defined width and are locked via the handle. Only authorized individuals can unlock a window sash via the keyed TiltFirst handle and disable the turn restrictor for cleaning purposes.

Also on display at the trade show in Munich was the Roto Glas-Tec | GL-UKS glazing block recommended for aluminum elements. The universal block has a 1.5 mm-thick 304 SST insert and a flexible, supportive surface. Thanks to its high inherent stability, the GL-UKS ensures load transfer of heavy glass even in challenging installations.

Roto helps design and produce aesthetically pleasing aluminum windows, renowned for their exceptional long-term functional performance and corrosion resistance. Roto Aluvision not only provides advice on state-of-the-art hardware product ranges, but also offers support working with weatherseals and glazing technology from Roto.
