What is Ultrex® and what makes it superior to other window materials?

Ultrex® is a pultruded fiberglass product patented by Marvin. Marvin creates Ultrex® by saturating strong glass cables with specialty compounded resins, pulling the glass cables through a heated dye and cutting them with diamond-edge blades. This creates windows that offer exceptional strength. In addition to being eight times stronger than vinyl, it resists expanding and contracting in any climate. So you get a tight, snug fit that will last.
