What Adexsi does
Adexsi is a France-based industrial group specializing in fire safety, natural smoke extraction, and building energy management solutions. Founded in 2000 and headquartered in Luynes, the company operates as a network of four sub-brands: Bluetek (smoke extraction, daylight, and comfort solutions for waterproofed roofs), Souchier-Boullet (smoke ventilation and comfort for roofs and facades), Langethermo (thermal insulation), and Tellier Brise-Soleil (sun shading and facade systems). Its product portfolio spans smoke ventilation skylights with pneumatic and electric opening mechanisms, vaulted roof lights, fire compartmentalization systems, facade bioclimatic solutions, sun shading, and a unified energy management platform called Genatis that bundles natural daylight, shading, natural ventilation, evaporative cooling, air destratification, and control automation.
Adexsi serves industrial, logistics, commercial, public, architectural, and residential building customers primarily through project-based B2B sales, with custom specifications and quotations per installation. Distribution combines direct enterprise engagement with building developers, architects, and facility managers in core European markets and a network of local distributors in international markets (e.g., SEAT TUNISIE in Tunisia). The company manufactures more than 95,000 devices per year across four production facilities in France, China, England, and Germany, and reports commercial presence in more than 40 countries. Notable reference projects include a pharmaceutical factory fitted with LamLight daylighting (2025), the Alba Mall rotonde renovation (2025), the Sotuchoc chocolate factory in Tunisia (2024), UrbanSoccer's RE2020-compliant Wetbox adiabatic cooling installation, and a 4,500 m² glass dome at Les Ormes Domaine & Resort fitted with C5-1 corrosion-rated Bluesteel Air electric skylights.
The company is privately held with no public listing or disclosed external investors. Revenue and financial performance are not publicly reported. The company is GDPR-compliant, products meet French RE2020 thermal regulations, and certain products carry C5-1 atmospheric corrosion classification. Management disclosure is limited to a responsible-for-publication officer and a data protection officer; no executive leadership team, headcount trend, funding history, or M&A activity is reported in available sources.
