Vinyl windows are made of plastic material and do not withstand changes in temperature as well as fiberglass windows. Integrity windows from Marvin Windows and Doors are comprised of Ultrex® pultruded fiberglass, which outperforms vinyl and vinyl/wood composites in virtually every measurable category. Plus, the production of vinyl windows requires more energy and resource consumption than the production of Ultrex®.
