Infinity fiberglass windows can immediately lower your home energy costs by up to 40%. Laboratory tests show that up to 40% of the energy used to heat or cool your Northern Virginia area home can be lost through windows and doors that are poorly insulated. Chantilly and surrounding area homes with such unsatisfactory insulation suffer from 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 are available in texture including traditional wood or a smooth, molded surface and are a better investment option compared to traditional wooden windows. Our patented Ultrex® fiberglass technology makes these windows energy efficient and tough, so they will open and close like they should every single time. Built on over 100 years of heritage from Marvin, Infinity windows remain weather tight and stable in all climates, reducing the risk of air leakage thanks to their low thermal expansion rate. With so many choices, Infinity windows are always customizable to meet the needs of any replacement project. These windows incorporate the details of traditional wood windows without the maintenance, so you will be confident that your investment is worth it from AN Exterior.

"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."
