What makes Infinity from Marvin Windows rank so high?

Compare Infinity windows to vinyl



  • Marvin’s Ultrex ® Pultruded fiberglass offers 8x the strength compared to a vinyl window – which allows the frames to be thinner and show you more of your outside than competitors. Because our finishes are 3x thicker than competitor finishes, Ultrex won’t crack, dent, chip or even peel. You can custom paint to your preference, and it’s virtually maintenance-free.  All of this makes Infinity the best looking window on the market.



  •  Our Low E metallic coatings on the inside of your glass panes are unnoticeable to the naked eye, but still offers superior protection against UV rays and heat/cold transfer. This keeps your window performing at its best without hindering your view.


*Independent Studies Confirm that Low E Glass Reduced Heating and Cooling Energy Usage by 20%



EverWood Finish

  • For those who prefer a more traditional look, Infinity’s exclusive EverWood finish is a beautiful engineered wood finish that can be custom stained or painted to match your home. The beauty of wood and the low-maintenance of fiberglass makes for a beautiful solution in your home.

EverWood has impressively realistic wood grain details on the interior that fool even the most studious observer into believing it's actual wood. These windows look, feel, paint, and stain like the real thing. Then, the exterior is made of engineered Ultrex fiberglass with a patented acrylic finish.



Results of the annual J.D. Power Windows and Patio Doors Satisfaction Study


Don’t take our word for it, J.D. Power’s yearly Window & Patio Doors Satisfaction Study Identified Marvin® Infinity Fiberglass Replacement Windows as receiving the highest score in appearance and design.  The study was a result of nearly 4,000 customers surveyed windows customers from the past 12 months, and we are pretty honored to be an exclusive installer of this line in Colorado.

“We pride ourselves on the fit, finish and attention to detail on all Infinity from Marvin windows and doors,” said Dan Marvin, Vice President at Infinity from Marvin. “It’s very rewarding to learn that homeowners who have purchased Infinity have found the same to be true in their own homes – and will continue to do so well into the future. We’re very grateful to our dedicated retail partners for the key role they play in homeowner satisfaction.”
