MI™ Windows and Doors has finalized its acquisition of Milgard® Windows & Doors from Masco Corporation. The acquisition combines two leading brands in the residential window industry and positions MI to become one of the most well-known window businesses in America.

Cultural Alignment
MI and Milgard share a similar culture defined by a hardworking, entrepreneurial spirit and more than 100 years of combined manufacturing experience and innovation. Both companies have grown considerably, but neither has lost the family-first values, window expertise, and customer focus that helped get them where they are today.

Complementary Strengths
Collectively, MI and Milgard are greater than the sum of their individual parts. As a highly recognized consumer brand that provides an industry-leading service experience, Milgard is a premium window and door manufacturer that focuses on the replacement and custom-home markets. Known for manufacturing throughput efficiency, MI has a reputation for consistently meeting the demands of the new construction and replacement window markets. As one, both companies are now equipped to better serve a more balanced and diversified customer portfolio.

Geographic Expansion
Milgard is one of the top brands in the Western United States, while MI has been historically strong throughout the East and South. Their combined reach and unique customer bases will enhance market share, synchronize regional penetration, and enable complete coast-to-coast coverage for the residential window and door market.
