Passiv Window

Norrsken’s Passiv window is based on our tilt and turn design but has improved performance due to an insulation layer laminated into the wooden frame and jamb. This lowers the u-value even further helping the window achieve greater thermal efficiency with a whole window u-value of 0.84 W/m²K.

Our Passiv windows are equipped with triple glazed, argon filled insulated glazing units with low-E glass and SGG Swisspacer V warm edge solution giving the glazing units a u-value of 0,6 W/m²K.

This made-to-measure window is available in timber or aluminium-clad timber and is available in any RAL colour or stain.
