Replacing your outdated vinyl or wood windows with Infinity fiberglass windows designed for optimal energy performance can help decrease your home’s energy costs. Scientific tests show that energy used to heat or cool homes is frequently lost through poorly insulated windows and doors. Whether in the heat of summer or the brutal cold of winter, Infinity fiberglass windows won’t expand or contract like inefficient vinyl windows. The low thermal expansion rate of Infinity fiberglass windows reduces the risk of air leakage, resulting in weather-tight window seals in your home.

“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.”
