What Cetih does

CETIH (Compagnie des Équipements Techniques et Industriels pour l'Habitat) is a French industrial group founded in 1976 and headquartered in Machecoul-Saint-Même that designs, manufactures, and distributes multi-material entry doors and windows for the residential habitat market. Operations are organized across six specialized factories in France (Machecoul Aluminium, Machecoul Bois, Roanne, Saint Macaire, Roncey, and Port Brillet) producing aluminum, steel, wood, PVC, and mixed-material products, with approximately 1,200 employees running multi-shift production. Technical highlights include the CENOV monobloc steel opening system (Ud 0.70 W/m²K thermal performance, RC2 security, class 3 resistance), RE2020-compliant eco-designed products using bio-sourced materials, and integration with Somfy and Delta Dore domotics systems.

The group commercializes its output through seven brands (Bel'M, Zilten, CID, SWAO, Bignon, CENOV, Bel'M Export) via a multi-channel architecture that combines direct B2B field sales to building professionals, GSB retail distribution, owned e-commerce storefronts, and EU/UK export. Revenue is generated primarily through hardware sales of doors and windows, complemented by a Qualiopi-certified professional training center (Centre de Formation CETIH) offering courses on installation, troubleshooting, regulation (DTU 36.5/20.1, RE2020), and domotics integration, with training fees ranging from €190 to €770.

CETIH has been a Société à Mission since 2021, validated by an external audit in 2025, and operates under a distinctive ownership structure led by the Superbloom family endowment fund alongside employee shareholders and three investment funds. Recent strategic actions include the 2022 acquisitions of Bignon and Novatech Europe (the latter enabling the CENOV brand in 2023), the 2024 France 2030 partnership with Synerpod and Airwell for collective/social housing energy renovation, the appointment of a Deputy CEO in January 2025, and the May 2025 cessation of the Koov residential renovation subsidiary to refocus on core industrial activities.
