Energy Efficient and Thermal-Passive Windows

In addition to our standard Double and Triple glazed products you can further reduce the heat loss in your building and minimize your energy consumption.

Nordica offers the latest versions of ultra energy-efficient windows. Our range of Thermal-Passive Standard windows are suitable where the criterion for the lowest possible U-value is specified.

Energy Efficient Windows

Nordica offers special windows with improved thermal insulation which can help you reduce the heat loss in your building and reduce your carbon foot print. These windows are slightly thicker than our standard system, the depth of both the wooden frame and the sash approximately 20mm deeper. The tilt & turn range, in addition, is equipped with 2 or 3 gaskets. The triple glazing with either Argon or Krypton achieves a centre pane U value U=0.5 W/m2K.

The biggest advantage of this system is very good thermal insulation with relatively low price.

This range is available as either a timber or aluminium-clad timber construction.

Our Energy Efficient range includes:
