4 years ago they changed windows at KBE GUTWERK 58 in the country house. Initially, I knew that this was a tender version of KBE (lite), an economical version. Everything is working fine so far, but the seals are disgusting. What does it have to do with co-extrusion in the company’s catalog leaf, and for some reason ordinary PVC stretched out on my windows (I noticed this after installation).
Our windows were made at a factory in St. Petersburg. I don’t know what it is. I believe that the manufacturer messed up. For some reason, the contact petal is not much thicker than paper. In general, the profile for the summer cottage approached normally (the load on the windows is not big, in the winter we are there only on weekends and do not spend the night usually. But I would not risk putting it home.
pros
price (saving on the face), now the cottage is warm, light and beautiful.
Minuses
quality corresponds to the price (for a summer residence and a garage it is quite suitable, but not for an apartment).
