Opus is a variation of Norwegian Classic window opening outward.

This model has a “hidden” hinge solution, which allows aluminium cladding and doesn’t affect exterior.

This so-called ‘housewife window’ is an ideal solution for ‘safe washing’ as it can be turned 180°, so you can safely wash the outside of window from inside.

Opus window is equipped with a child safety lock, this allows safe ventilation.

  Analogue of the Classic window, with “hidden” hinges system.
