Thermal insulation coefficient values of the windows Stars by QFORT:

Please find hereinafter the values of the thermal insulation coefficient relevant for QFORT thermal insulating windows.

The Ug coefficient represents the heat transfer value calculated at the level of the window glazing.

The Uw coefficient represents the heat transfer value calculated for the entire window.

The smaller the U coefficient is, the lower the heat loss and the better the thermal insulation of that building element are.

Energy-Saving with Windows Stars by QFORT

QFORT aluminium windows are equipped, in standard, with SuperLowE insulating glass (super low emissivity), warm spacers (warm edge technology) with two or three glass panes, a system rendering them a high thermal insulation characteristic. All these characteristics translate into considerably reduced costs for heating during winter and cooling during summer.
