Hello,
I have received two quotes for 18 doors for a single-family house. These include several fixed glazing units (including 1.88 x 2.15 m (6.2 x 7.1 ft)), patio doors (single and double), and upstairs windows (including 1.88 x 2.15 m (6.2 x 7.1 ft)) that have a fixed section.
Josko offered me the following: Kunststoff-Aluminium Safir 2.0 and fixed windows as Fix Blue,
Internorm: Kunststoff-Aluminium KF 520
The quotes include a fine texture surface on the windows, and the exterior window sills in aluminum are also coated. Electric aluminum blinds and electric aluminum roller shutters in matching colors are included. Everything with installation.
Internorm is about €6,000 cheaper. However, I am not sure if Josko’s windows are of higher quality or better. I prefer the appearance of Josko's windows, especially because of their very slim design, which looks really nice. The KF 520 are similar on the inside but look like fixed glazing on the outside.
Technically, Internorm offers RC2N and ECLAZ as standard, which Josko does not.
What do you think about these offers?

However, I will keep in mind the advice that proper and professional installation of the windows is more important than the product-specific differences.
