Infinity fiberglass windows can help to decrease home energy costs. Lab results show that the energy used to heat or cool your home can be lost when windows and doors are poorly insulated. Homes with drafty insulation often suffer from unnecessarily high utility 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 replacement windows look like traditional wood but are a longer-lasting option in comparison to traditional wooden windows. Infinity's unique Ultrex® fiberglass technology makes these windows energy efficient and tough, as strong as low carbon steel and 8 times stronger than vinyl. Infinity windows remain weathertight and stable no matter the weather, reducing the risk of air leakage thanks to the low thermal expansion rate of fiberglass. Available in a variety of standard types, sizes, and shapes, Infinity windows are also fully customizable to meet the needs of your home style. These windows incorporate the details of traditional wood windows without the maintenance, so you can confidently invest in Infinity windows from Juranek Home Improvements.

"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."
