Why Choose Infinity ?

The Infinity brand is Built for life®. Infinity Replacement Windows was created in 2002 when we recognized an opportunity to offer high-quality fiberglass replacement windows and doors for discerning homeowners, that are professionally installed by retailers.  Our products are made of Ultrex fiberglass and were designed by Marvin experts to replicate the look of traditional wood windows while providing modern features and low maintenance.  The combination of superior materials, design experience, and professional installation has resulted in a product line of high performing, energy efficient, and long lasting windows and doors.
