My father-in-law has been a window installer for about 30 years and installed the windows for me (with my help) as well as supplied them from his old company.
My assessment of the prices:
Window elements: In my opinion, good prices.
Installation: Seems a bit expensive. The choice of materials suggests an old-school (three-layer) installation. That is acceptable but not quite up to date. Nowadays, it's better to use (according to my father-in-law) compression tape that fulfills all tasks.
For the floor-to-ceiling elements, the sealing is missing for me; maybe it is included, but it is not clear from the material list (e.g., EPDM foil).
