There was a question about choosing a window profile for the kitchen and the hall. I wanted something German. KBE turned out to be expensive for me and then I came across Grunhaus. The price pleased me. All certificates are available (I went to their office to check). New windows are already standing and pleasing to the eye. I am satisfied!
The balcony of our bedroom overlooks a very noisy street. I wanted to find plastic windows with good sound insulation and dust protection. The German quality of the Grunhaus profile is just what you need. Now the room is comfortable and quiet.
