ENVELOPPE FAÇADE SERRURERIE

What ENVELOPPE FAÇADE SERRURERIE does

EFS Groupe (Enveloppe Façade Serrurerie), founded in 2018 and headquartered in Bon-Encontre near Agen in Nouvelle-Aquitaine, is a privately-held French SARL specializing in the building envelope trade known as 'Clos Couvert'. The group operates through four wholly-owned subsidiaries — EFS Projets (tender response and project delivery), EFS Solutions (engineering studies and site supervision), EFS Productions (industrial manufacturing of aluminum joinery and curtain walls), and EFS Installations-Maintenance (on-site installation and maintenance) — covering the full lifecycle from bid to fabrication and installation. Its core product lines include structural metal framework, cladding/bardage, external thermal insulation (vêtures), external joinery, curtain wall facades, metal staircases, and guardrails/balustrades, executed for both new construction and rehabilitation/renovation projects.

The company serves a diversified client base of public-sector project owners (regional councils, hospitals, schools), private developers, architects, general contractors, and specialist facade/locksmith subcontractors. Revenue is generated through one-off project contracts, professional service fees for engineering studies, manufactured-product sales, and installation subcontracting. Major disclosed contracts include a €1.35M curtain wall and skylight package for the new Meaux hospital, a €1.34M facade rehabilitation at Ilot Casteja in Bordeaux, and a €950K stair and guardrail package for the H2B educational building in Clichy. Geographic reach spans Grand Sud (Agen, Toulouse, Montpellier), Île-de-France (weekly presence), and selected projects in Lyon, La Défense, and Abidjan.

The firm holds OPQIBI certification (2025) for studies of complex metallic structures and lightweight facades, REYNAERS fire-resistance certification for CS77-FP and CW50-FP systems, French Fab community membership, and a Septuors Lot-et-Garonne 2021 award. Operational capabilities were extended in 2024 through a new manufacturing workshop funded by a €95,601 regional investment subsidy, and digitally through 3D and thermal-analysis software funded by a €47,554 digital transformation subsidy. With roughly 13–20 employees and €200,000 of share capital, EFS remains a small specialist contractor positioning itself as a vertically-integrated regional challenger in the French facade and metalwork market.
