What Sepalumic does

Sepalumic is a French designer, producer, and distributor of aluminum window, door, facade, veranda, and outdoor-living systems, operating as a gammiste (specialized range manufacturer) for the professional building industry. Founded in 1970 (with brand heritage exceeding 50 years) and headquartered in Mouans-Sartoux in the Alpes-Maritimes, the company is a wholly-owned subsidiary of the family-controlled Valfidus Group (founded 1952). Manufacturing is anchored at the Genlis (Burgundy) production site, which is solar-powered, with secondary production capacity on four continents through Sepalumic International. The registered capital is €1,000,000 in SAS form.

The product portfolio is built on a 70mm modular profile architecture with thermal break technology, spanning windows (series 6700, jalousie 2000), sliding glass doors (2600L/S cold range), French doors (5700), glass facades (W44 at 44mm face width, W52 curtain wall), verandas and extensions (Traditional 7700, Confort²Vie®, Espace²Vie®), bioclimatic pergolas, carports, gates, balustrades, brise-soleil, and cyclonic rolling shutters (2400 AC tested to 287 km/h). Profiles are produced from 100% low-carbon and 95% recycled aluminum with Qualicoat and Qualimarine coating certifications. The range is aligned with France's RE2020 energy regulations and 450+ RAL color options including bicolor configurations.

Sepalumic sells exclusively through B2B channels, serving four customer tiers: Artisan Créateur (fabricator-installers serving individual homeowners), Project (fabricators on construction sites), I-Process (industrial and prefabrication manufacturers), and International (ultramarine and overseas clients). Distribution runs through six regional offices — Sud-Est (Mouans-Sartoux), Nord-Est (Genlis), Nord-Ouest (Bourg des Comptes), Guadeloupe (Baie Mahault), Réunion (Le Port), and Morocco (Bouskoura) — plus four-continent depots and production units for export clients. Pricing is not publicly disclosed; quotes are project-configured through a dedicated customer portal (mon.sepalumic.com) and regional offices. Marketing combines digital channels (LinkedIn, Instagram, Facebook, YouTube, Pinterest), industry events (Batimat), an annual "Ouvrages" inspirational catalog, and value-added services (training, software partnerships, public-procurement support) for Artisan Créateur members, of which 55 companies had joined by January 2026.
