About us



The quality of our window joinery and services is confirmed by numerous groups of satisfied customers. We also have all the necessary and many additional certificates.


We are happy to share our knowledge, advising clients on the best solutions. We approach each project individually and flexibly.


Windows are our passion. That is why every customer can count on us to devote our time and do everything we can to ensure the highest satisfaction with our services. We do not finish our work at the time of delivery or installation of windows. Customers can always count on our support also after the warranty period.


Carefully selected products and technologies that we use guarantee durability and exceptional longevity of our services.



The history of our window factory dates back to 1996, when in Gdańsk at ul. Wałowa 35, Zakład Produkcji Joinery PCV started its activity. Eight years later, the SZACH-MAT brand was established. Almost thirty years of practice allowed for in-depth knowledge of the window joinery industry and establishing our own stable position of a window manufacturer on the market.


In the production process of our windows and doors, we only use materials from the world’s leading system providers. From the very beginning of our window factory, we have been working closely with the VEKA, Winkhaus, Saint-Gobain and Aluprof concerns, together striving to ensure that our products are among the best on the market.


We want to be for our clients something more than a supplier of the highest quality building materials. We want to become a partner for many years, whose help and support you can always count on. We are developing for you!
