Frameless sliding windows Soreg-glide, Sky-Frame, etc.

First of all the question about the goal: Do you want a maximum frameless view with the window closed, a maximum frameless opening with the window open, or both?

The decision has been made in favor of Soreg-Glide. Unfortunately, I cannot take the time to compare different systems or window manufacturers. Your contributions have been very helpful in assessing the price level. Thank you very much!

We planned our house according to the view on our slope, so from top to bottom. That means living, dining, kitchen on the upper floor. Sleeping, bathroom, dressing room, office on the ground floor. What do you think about my idea to design the upper floor with slim panoramic windows à la Ski Frame facing the view and to go with "normal track" on the ground and basement floors? How have the prices developed, the thread is now 3 years old.

We had the topic with our architect last year at the time of the extreme material prices when we were planning an extension for the kitchen. We were given a preliminary price of around 40,000 gross for a 3 x 6 m element for further planning.

"3 x 6 m element at 40,000 gross" - ouch!

We only laughed briefly and shortly thereafter put the entire planning on hold, as the single-story extension with about 36 sqm would have ended up costing almost 100,000 euros. But as I wrote, that was at a time when the maximum price for building materials had been reached.
