Hinge Side

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.

  • Offers superb burglary resistance up to RC 2 for concealed hardware
  • Fitted as standard with an anti-slam device and tilt restrictor
  • No accidental unhinging of the sash, thanks to the integrated anti-jemmy device and T locking system
  • 95° turn restrictor integrated in the hinges 
  • Permanent lubrication via patented lubrication depots for an easily maintained, permanently smooth running and low-wear system
  • With only two additional concealed load transfer components, the Roto NT Designo standard hardware can be easily upgraded with a standard tool from 100 kg up to a sash weight of 150 kg – with retrofitting also possible
  • Rational installation of the components, thanks to no or only minor preparatory measures on the sash. The stay arm rest and pivot rest always have a mirror-image drilling and screw-fixing pattern

The Roto NT Designo is particularly suitable for use in passive buildings, since no seals are interrupted and typical profiles can be covered:

  • Very deep profiles with narrow sash widths
  • Profiles with insulation filling
  • Profiles without steel

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.

  • Offers super burglary resistance up to RC 2 for concealed hardware
  • Fitted as standard with an anti-slam device and tilt restrictor
  • Maximum window opening angle of 100° for an uninterrupted view outside

  • Small variety of parts for lower production and storage costs
  • The combination of a clamping block and clamp-strip with a piercing screw guarantees solid interlocking and positive fitting clamping
  • Permanent lubrication via patented lubrication depots for an easily maintained, permanently smooth running and low-wear system
  • With only two additional concealed load transfer components, the Roto NT Designo standard hardware can be easily upgraded with a standard tool from 100 kg up to a sash weight of 150 kg – with retrofitting also possible
