To build high energy efficient houses Ecoclad use thermal windows with standard window thermal transmittance Uw = 0,88 W/m²K
Thermal windows have been manufactured of special timber profiles with the additional thermal insulation. The insulation material is added to the profiles during the lamination process before profiles are finished in the window factory thus ensuring the strength and integrity of the window frames.
Glazing units and hardware:
Thermal windows are equipped with the Argon filled insulated glazing unit with two low-E glasses and SGG Swisspacer warm edge solution; Ug = 0,6 W/m²K.
