U-Wert Fensterverglasung: Ug
The Ug-value is a function of the type of gas filling of the intermediate space between the glass sheets, the distance between the sheets and the number of sheets.
Typical U-values for thermally insulated windows are:
- Double insulated glazing 24 mm with argon filling: 1.1 W/m2K
- Triple insulated glazing 36 mm with argon filling: 0.7 W/m2K
- Triple insulated glazing 44 mm with argon filling: 0.6 W/m2K
- Triple insulated glazing 36 mm with krypton filling: 0.5 W/m2K
