Placoplatre SA, a subsidiary of the Saint-Gobain Group (which holds a 99.8% stake), is a leading European manufacturer of plasterboard, plaster-based products, and insulation solutions. The company's business model is centered around the extraction of gypsum and the manufacturing of finished building components for the residential, commercial, and industrial construction sectors. Its product portfolio includes plasterboards (marketed under brands like Placo, Placoplatre, Habito, and Lutèce), ceiling tiles (Gyptone), insulating linings (Placomur), and plaster tiles (Caroplatre). Placoplatre operates several manufacturing plants and gypsum quarries across France, including the largest underground gypsum quarry in Europe located in the Paris region. The company primarily serves the French domestic market but also exports within Europe. In addition to its core manufacturing activities, Placoplatre is a major player in the circular economy, providing gypsum waste recycling services to construction companies. Its competitive position is bolstered by its integration into the global Saint-Gobain network, its strong brand recognition (with 'Placo' often used as a generic term for plasterboard in France), and its extensive distribution channels.
