Triple glazing with a U-value of 0.7

Hello,

Does anyone here in the forum have experience with frameless windows with triple glazing?

I want to build a modern half-timbered house and have these windows installed.

Can someone name or recommend approximate prices per square meter and any manufacturers?

I am from the Stuttgart area.

How large and what properties should the windows have? In what kind of building would you install them?

Read the question again........

This time I can recommend something inexpensive to you. The company is called VITRON, I had to replace the windows in my house over a year ago, which of course is never among the cheapest investments. I had wood-aluminum windows installed and cannot complain, the insulation is perfect. I think they should also have frameless windows.
