What Bluetek does

Bluetek is a French industrial manufacturer specializing in natural smoke extraction (désenfumage naturel), zenithal daylighting, natural ventilation, evaporative cooling, and facade cladding for buildings. Formed in 2016 through the consolidation of three heritage specialists — SIH, Sodilight, and Hexadome — the company operates as the zenithal lighting and natural smoke extraction pole of the Adexsi group, a global roof waterproofing leader. Bluetek runs four production sites across metropolitan France, employs around 400 people, and produces more than 100,000 devices annually, with its portfolio organized into lanterns (Bluesteel family with thermal-break and cold-storage variants, Bluebac for dry/sandwich roofs), vaults (Bluevoûte, including RPT thermal-break models), tubular daylight conduits (Lightube, Lightube Office LED, Lightube TP Home), facade products (Kassette S, Harmonie blades, Komete brise-soleil, composite panels), adiabatic coolers (Adiabox, Coolea, Kit Adiaplay), and the Genatis integrated energy management platform.

The company's revenue model is hardware sales through a hybrid go-to-market: a regional direct sales force organized by French department, technical-commercial staff, a distributor and stockist network, prescription activity targeting architects and engineering prescribers (formalized under a dedicated Directeur Prescription since 2020), and export sales routed through parent Adexsi with project references in Germany, China, Czech Republic, and Algeria. Pricing is quote-based and not publicly disclosed, with regulatory eco-contribution unit fees (e.g., €1.21 per lanterneau, €76.01 per tonne of adiabatic cooler) added per French AGEC law requirements and paid to eco-organism Valobat. Customers are primarily building professionals — waterproofers, roofers, carpenters, electricians, control-system integrators, facade contractors, and distributors — alongside end-project references in retail, logistics, manufacturing, energy, public infrastructure, and hospitality. Product compliance with French fire safety and environmental standards (NF S 61-932, NF S 61-938, IT 246, 1200 joules, RE2020 via FDES on INIES) underpins specification in regulated projects.

Direct peers

• Souchier: French specialist in natural smoke extraction (DENFC) and natural ventilation. Souchier is the most direct French-headquartered competitor in Bluetek's core smoke-extraction skylight category, competing on the same NF S 61-932/938 standard.
• Colt International: UK/European specialist in Smoke and Heat Exhaust Ventilation Systems (SHEVS) and natural ventilation. Colt competes directly with Bluetek's DENFC (Exutoires de Désenfumage Naturel) product line and natural ventilation portfolio across European projects.
• Solatube International: US/Australian originator and global leader of Tubular Daylighting Devices (TDDs). Solatube is the most direct competitive analogue to Bluetek's Lightube product family, both for the pitched-roof TP variant and the Office LED commercial hybrid.
• VELUX Group: The world's largest manufacturer of roof windows and skylights, headquartered in Denmark. VELUX directly competes with Bluetek's Bluesteel and Bluevoûte product lines across residential and commercial daylighting, with substantially deeper international distribution.
• Fakro: Poland-headquartered global manufacturer of skylights and roof windows, the second-largest player worldwide after VELUX. Fakro competes directly with Bluetek's skylight portfolio in the residential pitched-roof and flat-roof segments.
• Roto Frank: German manufacturer of roof windows and skylight systems with strong presence in Central and Western Europe. Roto competes with Bluetek's Bluesteel Pass GD roof-access lanterns and related daylighting products in the commercial segment.
• Kingspan Light + Air: European daylighting, smoke vent and building-envelope ventilation business of the Kingspan Group. Kingspan Light + Air overlaps with Bluetek's daylighting/skylight products and with Bluetek's smoke-extraction portfolio at the European project specification level.

Regional players

• Wasco Skylights: US-based manufacturer of commercial skylights and daylighting systems. Wasco offers comparable products to Bluetek's skylight/daylighting portfolio but is primarily regional to North America with limited overlap in Bluetek's European footprint.

Broad incumbents

• BMI Group: Major European roofing group (formerly Braas Monier/Icopal) with pitched and flat-roof systems plus daylighting solutions. BMI competes with Bluetek at the roof-system level and benefits from broader brand and distribution scale than Bluetek's specialist focus.
• Honeywell Building Technologies: Honeywell's building automation division including smoke-control systems, HVAC controls and energy-management platforms. Honeywell overlaps with Bluetek's Asservissement et Pilotage product category and Genatis control layer, but as part of a much broader building-tech portfolio rather than a specialist.
