Introducing Ebony and Bronze All Ultrex Interior Finishes

This is Where Modern Begins

Integrity windows and doors are made with Ultrex®, a pultruded fiberglass we’ve patented that outperforms and outlasts vinyl, roll-form aluminum and other fiberglass composites. We use Ultrex and our proprietary pultrusion process to manufacture high-demand windows and doors that endure all elements without showing age or wear.
