DOUBLE GLAZED WINDOWS
Double glazed windows are the perfect choice for energy efficiency and noise reduction. The sealed air gap between the two panes of glass act as an extra layer of insulation, reducing the amount of heat which escapes out your windows in winter. However, during the summer months, the double glazing prevents unwanted heat from getting into your home. This saves energy as there is less reliance on heating and air conditioning throughout these month.

Outward Opening Double Glazing
The idea of an outward opening double glazed 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.
The construction of an outward opening double glazed 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.
In addition to the traditional side hung opening type there are also projecting opening types in DK’s product line to enable easy access for both sides of a window for cleaning purposes.
In DK Window’s product lines outward opening double glazed window is named DK-12 Window. It is best described as a traditional window with double glazing, slim frames and internal moulded profile (see the illustrations below).
