A Better Experience. That's MI.

We’re So Much More than Windows

Our Mission: Getting it Right Every Time

Homeowners are happy with their choices. Dealers feel great about selling. Builders and architects take pride in their projects. Team members celebrate their accomplishments.

We reach these successes by creating  first-class windows and experiences — bringing integrity to every relationship and precision to every detail — because we take your success personally.

As one of the nation’s largest suppliers of high-quality windows for remodeling, replacement and new construction projects, our customers count on us to provide a proven product backed by exemplary customer service that goes above and beyond.

There’s so much that goes on behind our windows to ensure a positive experience for homeowners, our professional partners and our team members — from the relationships we build, to our relentless attention to detail and state-of-the-art facilities.
