The New Roto AL Designo | STS 180° Concealed Hinge Side

Turn-Only and Tilt&Turn windows with inward opening sashes are the default choice in Europe. However, they are becoming increasingly popular in international markets traditionally dominated by different opening types like outward opening or hung/sliding windows. Roto Window and Door Technology (Roto FTT) offers a wide hardware product range for aluminum windows to meet this demand. One example of this is the new Roto AL Designo | STS 180° concealed hinge side for window sashes up to 176 lbs. (80 kg), a recent addition to the Roto AL Designo product line.

This concealed hinge side allows the sash to be opened up to 180°, while remaining suitable for flush aluminum profiles. As a result, it offers exceptional design flexibility, particularly for modern façade concepts and premium residential and commercial construction. The new hinge side is available for windows with the Turn-Only or Tilt&Turn opening type. It is fully compatible with components from the Roto AL modular hardware system, including all opening restrictors. This allows project-specific requirements to be met with flexibility.

Roto AL Designo | STS 180° is also one of the Roto hardware solutions certified as Cradle to Cradle Certified® Full Scope Bronze under Version 4.1. As such, aluminum window manufacturers have access to verified and assessed product information that can be used for tenders, building certifications or sustainability assessments.

All of the punched components in the hinge side are made from stainless steel and meet the highest requirements of corrosion resistance. This makes Roto AL Designo | STS 180° suitable even for applications where windows and hardware are exposed to harsh weather conditions. Additionally, the hinge side was subject to cycle testing, where it achieved 20,000 cycles.

The hinge side is designed for safe and economical processing. This way, it helps ensure fast installation in the factory or on the construction site.
