Infinity all-Ultrex fiberglass windows can instantly cut home energy costs. Lab evaluations show that the energy used to heat or cool your home can be lost through windows and doors that are not insulated properly. Homes with unsatisfactory and drafty insulation often suffer from high energy bills. The combination of poorly fitted frames, inefficient glass and porous wood or vinyl frame materials combine to waste the money you spend to keep your home safe and comfortable.

Infinity windows have the look of traditional wood, but are a longer lasting option compared to traditional wooden windows. Ultrex® fiberglass technology makes these windows energy efficient and strong, as strong as low carbon steel and 8 times stronger than vinyl. Infinity windows remain weather tight and stable even in the middle of summer, reducing the risk of air leakage thanks to their low thermal expansion rate. In addition to this variety of choices, Infinity windows can also be customized to meet the needs of any project requirement. These windows incorporate the details of traditional wood windows without the maintenance, making your investment in Infinity windows from P.J. Fitzpatrick, Inc. worth it.

“ 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. ”
