For attractive timber, PVC and aluminium windows with a 16 mm hardware groove that stand out by virtue of their high degree of comfort, exclusive design and numerous design possibilities, we can offer you – in the shape of our concealed hinge side Roto NT Designo - the ideal solution for up-scale home, apartment and construction projects.
The hardware system is well suited for flush window systems. Installation presents no problem, even with very narrow frame clearances.

Also, triple glazing ensures maximum stability in the case of heavy sash weights.
The completely concealed hinges of the Roto NT Designo emphasise the modern and clear appearance of the aluminium window. Only the window handle is visible, which sets the window off to perfection. The hardware system goes with almost all opening types.
