Infinity Replacement Windows offer a line of high performance windows and doors that consumers perceive as the quality and value leader in the industry. The Infinity line is:  Reliable, Durable, Innovative, Delivered Complete, Easy to Order, and Easy to Install!

Marvin Infinity Windows are made from a custom reinforced fiberglass composite pultrusion, making it one of the strongest, and longest lasting products on the market. Marvin's patented brand of fiberglass composite is known as Ultrex®, which combines continuous glass fibers with specially formulated resins, that are then cured with heat. After this process is completed, you are left with a product that is 8X as strong as standard vinyl, and 3X stronger than wood.

Ultrex® frames are also as low maintenance as they come, meaning that you'll never have to paint your windows again. However, if a splash of color is what you're looking for, the frames on Infinity windows are indeed paintable...and it won't even automatically void the warranty!

 Offering a variety of setup options, including Double Hung, Awning, Casement, Glider, Polygon, Bay, and Bow windows, the Infinity line of fiberglass replacement windows are built to uphold industry leading standards in both quality and performance. The Marvin family firmly stands by its' principals with the inclusion of The Five Point Proof system.
