MI Windows and Doors, LLC (MI) proudly manufactures its windows and doors in plants located across the USA, employing thousands of hardworking Americans to assemble millions of products annually. We use only high-quality components in the manufacture of our windows and doors, and all or virtually all the components used within our vinyl windows and doors originate in the USA.

The Federal Trade Commission (FTC) has published rules establishing when a company may rightfully claim that its products are “Made in the USA.” Like you, we value products that are “Made in the USA.” With only a single exception, all of MI’s vinyl windows and doors within the Series listed below are “Made in the USA.”

MI is committed to do what it can to help our country grow and prosper. One of the most important ways is to build our products in the USA employing Americans in the process. We are proud to be able to say, without exception, that all our windows and doors are assembled in the USA.

Founded in 1947 by two flight instructors who trained military pilots during World War II, MI has long provided jobs in numerous locations throughout the USA. Presently, our company employs nearly 2,500 team members—and we’re growing.

At every one of our facilities—from rural Pennsylvania to suburban Dallas to the Phoenix-area suburb of Prescott Valley—MI provides well-paying jobs to hardworking Americans. These employment opportunities at MI facilities contribute to the economic vitality of those regions.

At MI, we love being a part of building America, whether it’s manufacturing products used in the building of homes and office buildings, or building the local economies of the regions in which we’re located. This is the vision our founders had for the company from the beginning. It’s the vision we’re seeing through to this day.

*All 1600 Series products meet the requirements for Made in the USA except the 1615/1617 sliding glass door.
