Infinity's fiberglass windows and doors harness the strength of their proprietary Ultrex® material. Ultrex is 8x stronger than vinyl so you can enjoy more daylight in your home with thinner frames. Feel confident about fiberglass providing a low-maintenance replacement option that will deliver long-lasting performance, backed by Infinity's Limited Lifetime Warranty.
We attended the Spring Home Show and looked into 3 different brands of windows. We did our research and were most impressed with Infinity from Marvin. Not only because of the window itself but also because they could match the oak floors, trim, and oak cabinets. Not only did they match it but it looks incredibly beautiful. We chose to add the bow window. It was perfect. Steve was a knowledgeable and sincere salesman. The service was incredible, the installers, more incredible. The team sent up here were meticulous about every fine detail of the installation and very thoughtful about our time, home and space. And...the windows are fantastic. Good investment. Highly recommend them over other name brands.
