Infinity Replacement Windows

Infinity Windows from CRS Exteriors in Knoxville, TN

CRS Exteriors is the replacement window company Knoxville depends on to provide long lasting products and first-rate, lifetime service. Our objective is to make your home feel more aesthetically pleasing, polished, and comfortable, all while delivering a home remodeling experience that is pleasant and stress-free. Aside from Infinity replacement windows from Marvin, CRS Exteriors Custom Replacement Services also offers sunrooms, siding, and doors.

Innovative replacement windows by Infinity can help lower your home’s energy costs by as much as 40%. Lab results show that up to 40% of the energy used to heat or cool your Knoxville area home can be lost through windows and doors that are poorly insulated. Knoxville and surrounding area homes with outdated installations often suffer from unnecessarily high energy bills.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.

‘Built for Life’, Infinity replacement windows can have the texture of traditional wood or a smooth, molded surface but are a 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. Built on more than 100 years of heritage from Marvin, Infinity windows remain weather tight and stable even in extreme weather, reducing the risk of air leakage thanks to a low thermal expansion rate. With so many types and sizes, Infinity windows are also customizable to meet any replacement needs. These windows incorporate the details of traditional wood windows without the maintenance, so you will be confident that you made the right choice choosing Infinity from CRS Exteriors.

If you want to know more about replacing your windows with Infinity Ultrex fiberglass options, contact CRS Exteriors 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."
