In November 2018, Ply Gem Building Products and NCI Building Systems merged together to become the single largest manufacturer of exterior building products in North America. Better together, the combined organization offers unparalleled expertise in creating products and solutions for the commercial and residential construction industries and delivers on decades of experience serving customers and communities across North America. Since 1984, NCI Building Systems has grown through strategic mergers and acquisitions. Now part of Cornerstone Building Brands, the organization continues to design, manufacture and deliver a comprehensive range of products for the commercial construction industry—from metal coatings to components, and from insulated metal panels to engineered building systems. For over 75 years, Ply Gem Building Products has been a pioneer in the residential construction industry, and it continues to lead through innovation. Ply Gem`s comprehensive range of building products includes nearly everything on the outside of a home: from windows, doors and siding to designer accents, stone veneer, roofing and fence and rail. All of Ply Gem and NCI`s commercial and residential building brands will continue to go to market through their existing names, and the company will continue to leverage the Ply Gem endorsement across our residential product categories. Moving forward, the NCI Building Systems brand name will be replaced by Cornerstone Building Brands.
