BG21 Aluclad windows (2- or 3-glazing)

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.

 

BG21 aluclad window provides traditiona Scandinavian window design together with external powdercoated aluminium cladding profiles. There is also an option to choose between 2-glazing or 3-glazing.

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.
