When it comes to windows and doors, one size rarely fits all. You want solutions that are not only functional, but also beautiful, durable, and perfectly suited to your design vision. At Bertrand, that’s exactly what we offer – and much more.
We’re not your typical window and door manufacturer. We’re a family-owned business from Poland with over 55 years of experience and a passion for creating custom, high-quality products that elevate homes and buildings across the world – including right here in the United States.
European craftsmanship, built for the U.S. Market
Bertrand has earned a strong reputation for combining European design standards with the certifications and performance features expected in the American market. Whether it’s NFRC-compliant windows, impact-resistant glass for hurricane zones, or large-scale custom sliding systems – we know what U.S. architects, builders, and distributors need.
Our modern production facilities house advanced machinery and skilled technicians who treat every order like a unique project. We focus on tailor-made solutions – from historical window replicas to oversized aluminum-glass façades or multi-panel lift-slide doors.
