Viwinco in Morgantown PennsylvaniaFamily-owned and operated since 1982.

We entered the window manufacturing business almost 30 years ago and are proud to be a leader in the industry today. We design and manufacture vinyl windows and patio doors for both the new construction and replacement industries.

Viwinco stands for high quality. We continuously look to enhance our product offerings both in looks and function while providing you the energy-efficiency you want for your home. Every window we produce is custom-made to your exact specifications so you can be sure of a perfect fit and installation every time. Best of all, we can make your custom vinyl windows in just 7 days.

With our 140,000 square-foot, state-of-the-art fabrication plant and 30,000 square-foot Research & Development facility, we have created manufacturing processes that enable us to also produce our own specialty glass including tempered (also known as safety glass) and laminated glass (which is impact-resistant) in-house as well as the unique shapes of geometric windows, all within the most aggressive of construction schedules.

Thanks for your interest in our vinyl windows. We guarantee you'll be happy with your new Viwinco replacement windows or our new construction ones!
