Allegheny Millwork offers a wide selection of quality and style for the windows in your home. Some of our products can be used on both residential and commercial applications. In both cases, we can customize sills, casings and colors.



SIGNATURE COLLECTION – Previously known as Marvin Windows and Doors

The Marvin Signature Collection offers the broadest range of product types, sizes, configurations and design options.  You’ll experience the difference in every thoughtful detail, with the highest level of architectural precision and beautiful aesthetics.  Featuring the Ultimate and Modern product lines, the Signature Collection is a hallmark of Marvin’s design leadership and customer-focused innovation- made to inspire truly exceptional spaces.

ELEVATE COLLECTION – Previously known as Integrity Wood-Ultrex®

The Elevate Collection is an ideal blend of remarkable design and superior strength, bringing balance to your style and performance needs.  Patented fiberglass exteriors stand up to all elements, outperforming and outlasting vinyl, roll-form aluminum and other fiberglass composites. Warm wood interiors add timeless beauty, while resilient, long-lasting fiberglass stays strong in even the toughest conditions.

ESSENTIAL COLLECTION – Previously known as Integrity All Ultrex®

The Essential Collection brings together design, quality, and performance in one streamlined offering. Strong, durable fiberglass exteriors and interiors are both striking and virtually maintenance-free. Simplified options make the order process straightforward, while clean lines and versatile styles make it easy to meet project demands.
