Roto Logo

Window design demands increase in an attractive home. Our concealed hinge side Roto NT Designo masters this discipline with bravura: No hinges visible from the outside, no caps – nothing detracts from the window’s appearance because the less we can see of the technology, the better! The hardware system is suitable for timber, PVC and aluminium windows with 16 mm hardware groove.

Suitable for:

  • Tilt&Turn / Turn-Only windows in timber and PVC
  • For sash weights up to 150 kg
  • Installation, maintenance and operation instructions for PVC windows and balcony doors available from DGS.
