Infinity patented windows can instantly reduce you home energy costs by as much as 40%. Laboratory tests show that up to 40% of the energy used to heat or cool your Grand Forks area home can be lost through poorly insulated doors and windows. Grand Forks and surrounding area homes with drafty insulation 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 and look of traditional wood, but are a longer lasting option in comparison to traditional wooden windows. 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 these windows remain weather tight and stable even in the winter months, reducing the risk of air leakage thanks to their low thermal expansion rate. With so many different options Infinity windows are always customizable to meet the needs of any replacement project. They incorporate the details of traditional wood windows without the maintenance, so you will be confident that you made the right choice by choosing Infinity from Windows Plus.

"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."
