Infinity Replacement Windows

Infinity Windows from Lifetime Windows & Siding in Denver, CO

Lifetime Windows & Siding is Denver’s top provider of new & replacement windows and siding. At Lifetime Windows and Siding, we know the benefit of high quality, energy efficient windows and siding for your home. Whether it’s new vinyl siding or replacement windows from a recent hailstorm, we are ready and willing to help. There are a variety of reasons why replacement siding or windows could be a great benefit to your home.

Infinity fiberglass windows can help to cut your home energy costs. Lab evaluations show that up to 40% of the energy used to heat or cool your home can be lost through windows and doors that are poorly insulated. Denver and surrounding area homes with unsatisfactory windows often suffer from 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 have a texture that looks like traditional wood, 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 so they will open and close like they should every single time. Infinity windows remain weather tight and stable in all climates, reducing the risk of air leakage thanks to the low thermal expansion rate of fiberglass. Available in a variety of different options, Infinity windows are also fully customizable to meet the needs of any replacement project needs. They incorporate the details of traditional wood windows without the maintenance, so you will be pleased that your investment was worth it from Lifetime Windows & Siding.

If you want to know more about replacing your windows with Infinity Ultrex fiberglass options, contact Lifetime Windows & Siding 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."
