The Roto Patio Alversa system allows us to produce parallel glazing elements that also have a tilting frame ventilation option. All the components of the closure system are developed by Roto and manufactured in Roto factories to ensure Roto's renowned quality and reliability of supply.

Advantages of Roto Patio Alversa:
- the combination of a universal central locking (Roto NT/NX), a universal handle and a modular sliding system reduces costs in production, storage and logistics to a minimum.
- all variants are manufactured using standard window profiles.
- improved ease of use thanks to an innovative opening and closing mechanism that allows the sliding element to be moved smoothly and quietly.
- all parallel sliding systems are handled intuitively in the same way as standard windows.
- the use of standard handles, e.g. RotoLine and RotoSwing models, creates a uniform visual impression of a living space with sliding and standard window elements.
- With the Comfort solution PS Air Com, the frame automatically moves to the tilting position when the handle is turned.
- different security classes - for a secure home, you can choose break-in protection with Roto security components, e.g. security shutters.
