Infinity patented windows can help to lower your home utility costs by 40%. Laboratory results show that up to 40% of the energy used to heat or cool your Buffalo area home can be lost through poorly insulated doors and windows. Buffalo and surrounding area homes with 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 replacement windows are available in the texture to look like traditional wood or a smooth, molded surface but are a more dependable option in comparison to traditional wooden windows. Our 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 weather tight and stable no matter the weather, 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 needs. These windows incorporate the details of traditional wood windows without the maintenance, so you will be pleased that you made the right choice choosing Infinity from Big L.

"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."
