  • The PRIMO patio doors surprise you with simplicity that places functionality and design first. When creating WIŚNIOWSKI doors and windows, our designers and engineers primarily thought about what each home needs. We know how important the sense of safety, security, and reliability is. It remained our priority throughout the long process of designing the PRIMO patio doors. All the functional advantages of our PVC doors and windows are highlighted by their state-of-the-art design, the simplicity and elegance of which will be a joy to look at for many years to come.

    PRIMO is the result of three decades of experience and efforts to create perfect windows and patio doors.
