Roof windows - What costs?

Yes, I believe that. Apparently, there aren't actually that many [Erfahrungswerte] ad hoc, as it seems.

But kaho. This is not a guessed price, but the paid surcharge for 1 Velux in the roof instead of nothing.

I think 1000 euros is a good starting point. Depending on size and equipment, it can also be 800 euros or 2,000 euros

Double-glazed plastic approx. 800 euros e.g. Roto

Plus installation/travel 3-4h x 60 euros.

We paid about 1800 per piece for triple-glazed and somewhat larger, including installation

Wow, 1800 is then a bit more. Is triple glazing not automatically mandatory in living areas? : is the Velux triple glazed? How big is it approximately?

Triple glazing is not yet commonly standard for roof windows. Usually also thicker insulated frame.

Financially, it usually does not pay off. In winter, the snow also stays on.

1,800 euros for triple glazed 140x140 electrically operated with rain sensor I find okay.

Double glazed. Large. Like a woman.
