General Information: MI operates coast-to-coast as a vertically-integrated manufacturer of vinyl and aluminum products, serving the new construction, replacement and light commercial markets from plants in Arizona, Pennsylvania, Tennessee, Texas and Washington. In 2011, the company launched a new casement window platform designed for superior thermal performance and incorporating new upgrade features. MI also launched the MI EnergyCore Window System from its Prescott Valley, Ariz.-facility. The product line uses unique Air-Cell PVC frame technology, as well as high-performance glass to offer upgraded performance. The company used an iPad application and social media as vehicles to announce and support the launch of the new line. The construction downturn has taken a toll on the company. In 2010, MI closed a manufacturing plant in Van Alstyne, Texas. That move followed the closing of a North Carolina plant in 2009 and an Indiana facility in 2008. With a 60-year history in the building product category, MI got its start as Metal Industries, manufacturing screens in an old airplane hangar in Clearwater, Fla. It first began manufacturing storm windows in 1972, storm doors in 1974, then introduced vinyl replacement windows in 1981. It also owns General Aluminum Corp., a window manufacturer in Carrollton, Texas, and produces CertainTeed brand windows for the Eastern half of the U.S. MI’s parent company is J.T. Walker Industries, is also the parent company of RiteScreen, the screen manufacturing operation based in Elizabethville, Pa.
