About Us
Who We Are?
Imagine a company where window and door manufacturing isn't just production, but a passion passed down since 1995. That's us – BWS Technika Budowlana. For nearly 30 years, our factory in the heart of Lubliniec has been creating windows, exterior doors, roller shutters, and conservatories that become the soul of over 10,000 homes and the calling card of businesses in Poland and worldwide. Our specialty is custom-made windows in PVC and aluminum, precisely tailored to your individual vision. We know that windows are an investment in your family's comfort and security for decades to come. That's why we approach every project with craftsmanship precision and personal commitment, paying attention to every detail of execution.


What Sets Us Apart?
Experience Backed by International Recognition
Do you know what nearly three decades in the industry brings? The certainty that quality isn’t a slogan, but the sum of daily, conscious decisions. That’s why we base our production exclusively on proven profile and hardware systems from renowned leaders like GEALAN and MACO, guaranteeing reliability and trouble-free operation for decades. Our energy-efficient windows with triple glazing easily meet the rigorous standards of the Polish Clean Air Program and WT 2021 building regulations, offering a standard U-value below 0.9 W/(m²K) – which means real heating savings of up to 30% annually for you. For the most demanding projects, we create solutions with U-values as low as 0.7 W/(m²K). This uncompromising quality has earned recognition in demanding markets, including Germany and Austria, where our products are valued for their precision craftsmanship. Every window undergoes our 5-stage quality control process before reaching you, including profile verification, weld precision checks, and hardware functionality tests – because your trust is priceless to us.

Purchasing windows is a decision for years to come, which is why you’ll never be alone with it. At BWS, we’re your partner at every step of this journey. We begin with professional consultation and precise on-site measurements at your property to perfectly understand your needs and architectural possibilities. Then, in our factory in Lubliniec, your order takes shape under the watchful eye of experienced specialists.
