Infinity From Marvin Windows

We are excited to represent Marvin Windows in our area. Since 1912 Marvin Windows has been providing custom-tailored windows designed to perform in our Wisconsin winters. Our specialty is window replacement and in the early 2000’s Marvin unveiled a new line of windows specific to the replacement market called Infinity. Infinity from Marvin are constructed with a fiberglass base and include several interior and exterior finish options.

Replacing your windows often means entering into uncharted territories for homeowners. You’ve never done it before and, hopefully, will never have to do it again. We are here to help provide a clearer understanding of what’s available in the replacement window market, but also set the expectation of how a reputable remodeling business should treat you. Let’s get to work.

There are many ways to approach window installation. The video below walks through the two most common – insert window replacement and full frame replacement. Insert windows typically fit inside of the old frame and are used where we know the old frame is in good condition and the window opening can accommodate the new window. Full frame is installing a new window by removing the old frame and installing into the rough opening. It is most often used where the old frame is dilapidated or there are other concerns beyond the frame.


Warranty is a word that can mean a lot of different things. In the window replacement industry, it’s not uncommon for people to throw around words like “lifetime” without much respect for what that term actually means.

We look at things a little differently.

  1. We wouldn’t be here if we didn’t take care of our customers.
  2. We chose our manufacturing partners based on their ability to deliver on their warranty to both us and our customers.
  3. We believe it’s important to have an accessible copy of your warranty – even before you make a purchase. Here’s the Marvin Infinity Warranty.
    • 10 year warranty on manufacturing defects, materials and workmanship.
    • 20 year warranty on insulating glass.

Take the time to evaluate different warranties before assuming they cover what you need. Many vinyl window manufacturers will not provide their  warranty until the job is complete and paid in full. We’re different and that’s just one of the many ways we go about this process with YOU in mind!

Infinity streamlines your entire window replacement project — from start to finish.
