Infinity fiberglass windows feature Ultrex technology that can help to reduce home energy costs by as much as 40%. The energy used to heat or cool your home can be lost through poorly insulated doors and windows. A house with drafty insulation often results in unnecessarily 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 replacement windows may look like traditional wood, but are made with fiberglass which makes them a longer lasting and more efficient option in comparison to traditional wooden windows. The patented 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 weather tight and stable even in extreme weather. Air leakage is reduced thanks to fiberglass' low thermal expansion rate. Available in a variety of typical shapes and sizes, Infinity windows are also completely customizable to meet the needs of any replacement project and any space in your home. They incorporate the details of traditional wood windows without the maintenance, so you'll be confident in your investment in Infinity windows from Nu Vu Windows & Siding.

If you want to know more about replacing your windows with Infinity Ultrex fiberglass options, contact Nu Vu Windows & Siding in Grimes, IA today for a free estimate.

"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."
