Marvin Integrity replacement windows and doors are made from a pultruded fiberglass material patented almost 20 years ago when Integrity pioneered fiberglass windows and doors. Marvin Integrity has led the fiberglass category from the start with a strong commitment to a product that is very tough, long lasting and worry free.
Facts prove that Ultrex is possible the best building material for windows and doors. Ultrex is durable, strong, stable, and low maintenance. Integrity windows and doors made with Ultrex fiberglass outperform rolled aluminum, vinyl, and vinyl/wood composites in virtually every measurable category. Other windows may break, bend or crack over time; Integrity windows remain strong and perform under stress without showing age or wear.
The Ultrex exclusive finishing process is three times thicker than similar finishes to resist scratching and marring. It also provides five times the UV resistance that guard against cracking, chalking, fading and streaking.
