Saint-Gobain operates 400+ industrial sites in 76 countries and employs ~160,000 people — one of few companies that spans the entire building envelope: glass (SGG, Sekurit), insulation (Isover glass wool, stone wool), gypsum board (CertainTeed, Gyproc), exterior renders (Weber), and roofing (CertainTeed). In the US residential construction market, a single-family home could contain: CertainTeed drywall, Isover glass wool insulation, CertainTeed roof shingles, and SGG window glass — all from the same 360-year-old French manufacturer. Saint-Gobain's building materials reach into the US market has grown substantially through acquisitions; CertainTeed alone is a top-3 US gypsum wallboard and insulation brand. A French royal glass company is a dominant supplier of US housing construction materials.
