We only offer and use products from the best brands in the industry. Many of the products we offer are made in Poland (by large brands such as Wisniowski, Eko-Okna, Wiked), who is one of the biggest manufacturers of windows and doors worldwide and is well known for the outstanding quality of these products. In 2021 polish manufacturers provided 36.2 % of total worldwide PVC window supply, 28% of wooden windows and 9.2% of aluminium windows.
We also provide products of French and German brands, made locally in those countries.
Both fully assembled products as well as components and raw materials used by KTB, come from well- known brands offering the highest quality possible. Only the best European profiles like Aluplast, Aluprof, Ehret, Veka, Salamander and Schuco are used in our work.
Pergolas, shutters and blinds KTB offers come from a handful of manufacturers, who are the best in their field, like Ehret, Lakal and Art Home Alu.
