J.T. Walker and Robert J. Word started the company in 1947 at a Florida airplane hangar making screens. These hardworking, visionary founders never forgot the value of good people as the company continued to expand. MI began manufacturing storm windows in 1972, storm doors in 1974, then introduced vinyl replacement windows in 1981. In the 1990s, MI brought its hard work and expertise to the new construction market, purchasing Capitol in the early part of the decade and BetterBilt in 1999. In 2004, MI adopted a new name, MI Windows and Doors, and a new tagline, "Seeing You Through." In 2006, MIWD partnered with CertainTeed, and in 2007 it simplified it's branding strategy to consolidate its' brands under the MI Windows and Doors label. In 2008 MIWD launched the BridgeWood product line and in 2011, the MI EnergyCoreâ„¢ Window System.
