Aluminium windows thermal insulation

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.
