The idea of an outward opening window is developed in Scandinavian countries in harsh climate conditions: in Denmark and in Norway such windows have been the main solution in building practice. 

Viking21 window provides traditiona Scandinavian window design with the option to choose between 2-glazing or 3-glazing.

For more detailed information, please contact our sales department and see the drawings.

The construction of an outward opening window is designed to have excellent performance and functionality during different season through the year: in high humidity, in dry conditions, while it is cold or hot. Gaskets and insulated glazing units used in the design ensure air tightness and energy efficiency. Carefully chosen wood and the use of tested hardware prolong window's life span.

Features of Viking21 window:

  • choice between modern look with square edged of traditional looking grooved internal profiles;
  • wooden and aluclad option;
  • well proven range of different opening types including side projecting, top swing, top hung and side hung;
  • projecting opening types in Viking's product line to enable easy access for both sides of a window for cleaning purposes;
  • 2- or 3-glazed option with the same frame profiles and opening types range for both timber and aluclad windows;
  • 26 mm glazing unit for 2-glazed window;
  • 48 mm glazing unit for 3-glazed window - which conforms to modern energy efficiency;
  • handle is always in the centre of sash profile;
  • PAS24 UK security tested design.
