Our history is rich with milestones of growth, all of which reflect our basic commitment to great customer service, quick product delivery, and cost-efficiencies for you. Founded in 1968 in Dallas, Texas, we were first known as Controlled Building Systems Corporation. In the mid-70’s when we were part of Hussman Corporation, we were renamed Metl-Span Insulated Panel Division. Returning to private ownership in 1983, we relocated our operations to a new, greatly expanded facility in Lewisville, Texas to accommodate our burgeoning growth.

In 1990 with a minority investment by Grupo IMSA, we developed our first continuous foamed-in-place production line. In 1994 Grupo IMSA acquired us outright and within just a few years approved our expansion into Virginia. That expansion doubled our production capabilities and improved our ability to serve the eastern region of North America. In 2005 we opened our third production facility in Nevada, enabling us to serve the western region of the US. In 2007 we grew again and began operations in our fourth facility based in Indiana. That expansion effort enabled us to better serve our customers located in the central states of the US.

In 2008 we were purchased by BlueScope Steel Limited, the global leader in high quality metallic coated and painted steel solutions for the building and construction sector. In 2012 we were purchased by the NCI Group, Inc; now known as Cornerstone Building Brands. Cornerstone Building Brands is North America’s leading exterior building products manufacturer.
