Benefits of Fiberglass Windows by Marvin

Marvin has succeeded in creating one of the most perfect building materials on the market today: Ultrex pultruded fiberglass. This material is exceptionally:


One square inch of this state-of-the-art material can support an astonishing 34,000 lbs. In fact, fiberglass frames are eight times stronger than vinyl and three times stronger than vinyl/wood composites. Instead of succumbing to high winds and impact from hail and windborne debris, fiberglass can bend and flex, withstanding the most brutal conditions year after year.


Ultrex fiberglass windows boast an acrylic finish that is three times thicker than competitive finishes, so they retain their vibrancy without cracking, denting, chipping or peeling over time. They also boast the look and feel of traditional wood but without any of the high-maintenance pitfalls associated with it.

Energy efficient

Our fiberglass windows combine the low conductivity and exceptional performance of Ultrex with a number of energy-efficient glazing options that will reduce heat loss in your home and potentially help you save on monthly energy costs.
