Thanks in advance for your opinions. I will discuss this again with the window manufacturer, but at the moment I tend to prefer the triple-glazed ones, especially since you can still take advantage of the KFW subsidy there. If I have read correctly, this is rather difficult with double-glazed windows because the U-value is not low enough. I hope I have understood this correctly.
