The Ultrex difference

Integrity windows should be considered for any new construction project. All window types are available in many standard sizes with a choice of three exterior finishes. Integrity windows are able to offer both performance and beauty because of a revolutionary material created to be virtually impervious to the ravages of time, heat, cold, and pressure. It's a pultruded fiberglass called Ultrex, and more than ten years ago it was developed by Marvin for the exteriors and structural backbones of windows and doors. Combining Ultrex with classic wood interiors, Integrity windows are low-maintenance and long-lasting. Ultrex along with a high-performance acrylic coating make it resistant to cracks, scratches, and dents. Unlike roll-form aluminum which can be dented by hailstones or an errant baseball, Ultrex stands up to everyday challenges and maintains a flawless appearance for years. Integrity windows are built to do more than look beautiful. They are built to perform.
