Vitrum Glass

What Vitrum Glass does

Vitrum Glass (VitrumGlass) is a French specialist founded in 2012 and headquartered in Le Mans, operating as a bureau d'études that designs, supplies, and installs high-end active and intelligent glazing systems. Its portfolio centers on four core technologies — Vitrage Chauffant (electrified heating glass using metallic microparticle coatings to emit low-temperature infrared radiation), Vitrage Opacifiant (switchable privacy glass using liquid crystal film between laminated panes), Vitrage Dynamique Solaire (electrochromic glass that transitions between tinted and clear states to control solar gain), and Vitrage Chromatique (passive thermochromic glass that self-tints with sunlight) — complemented by glass radiators, connected smart mirrors, blackout glazing, and retrofit films. The company is co-founded and led by Manuel Dariosecq and Estelle Chollet (Directrice commerciale), with a sub-10-person core team augmented by a partner ecosystem of glass makers (notably an exclusive relationship with Riou Glass), electricians, aluminum/metalwork firms (e.g., HATTON), and window manufacturers.

The business model is hybrid and project-driven. Professional installations are priced at €600-€1,500/m² (HT) depending on technology, encompassing thermal/electrical engineering studies, product supply, and certified installation. Standardized products (glass radiators €529-€1,968, smart mirrors €399-€598, heat-control and opacifying films) are also sold direct-to-consumer through a WooCommerce/Stripe e-commerce boutique. Distribution combines direct field sales (recruiting dedicated Technico-Commercial reps for the Grand Ouest and Paris territories), a network of architects and designers who specify the products, and partner installers — all operating exclusively in France. Customers span residential homeowners, hospitality (Hôtel Bristol Paris, Le Splash restaurant, Bakus Wine Bar), municipal government (Hôtel de Ville du Mans, Abbaye de l'Epau), education (École Michel-Ange, a world-first school installation), healthcare, and enterprise (a major Paris telecom group). VitrumGlass holds CE, RGE, LCIE, and Made in France certifications, offers a 10-year warranty on most products, and reports up to 40% energy savings versus traditional heating. The company is privately held by its founders with no disclosed external funding, no M&A activity, and no patents of record in the input data.

Scale indicators6 records

Recent moves6 records

Expansion highlights6 records

Broad incumbents

• SageGlass (View Inc.): View's SageGlass is the global leader in electrochromic smart glass — directly comparable to VitrumGlass's dynamic and opacifying glass lines, but operating at massive scale with multinational building deployments, whereas VitrumGlass is a regional French specialist.
• Saint-Gobain Glass: Saint-Gobain is one of the world's largest glass manufacturers with active/smart glazing product lines (e.g., SageGlass-compatible, ECLAZ) and a French headquarters. It competes with VitrumGlass for architect specifications and large commercial glazing tenders in France.
• AGC Glass Europe: AGC (formerly Glaverbel) is a major European flat-glass and coated-glass producer with electrochromic and solar-control product lines that overlap with VitrumGlass's dynamic and chromatic glazing technologies.

Direct peers

• Gauzy: Israeli-based Gauzy is a manufacturer of switchable (SPD and liquid crystal) smart glass films and finished products used in architectural, automotive, and consumer applications — directly comparable to VitrumGlass's opacifying and dynamic glass offerings.
• Smartglass International: Smartglass International specializes in switchable privacy glass for architectural and healthcare use cases — directly comparable to VitrumGlass's vitrage opacifiant and partition applications.
• ChromoGenics: ChromoGenics (Sweden) produces thermochromic and electrochromic dynamic glass for buildings — directly comparable to VitrumGlass's vitrage chromatique and vitrage dynamique products for solar control.

Emerging players

• Riou Glass: Riou Glass is VitrumGlass's exclusive French glass-manufacturing partner for high-performance glazing. It is comparable because it sits upstream in the same specialty-glazing value chain and could in principle supply end customers directly, potentially disintermediating VitrumGlass.

Others

• ThermoUp: ThermoUp is referenced as the technology provider for VitrumGlass's Dry and Dry Side glass radiator product lines — a supplier/partner rather than a direct competitor, but materially comparable because ThermoUp could itself enter the French glass-radiator retail market.

Regional players

• Verrières du Sud / local French glazing installers: Regional French glazing contractors that install verrières (interior steel-framed glazed partitions) compete with VitrumGlass on the residential and small-commercial skylight/atelier segment. They typically lack electrified smart-glass capabilities, positioning VitrumGlass at a premium tier.
• Atlantic'Glass / Tryba (French glazing networks): Tryba and similar French glazing retailer-installer networks compete in residential window replacement. They overlap with VitrumGlass on installation services for the French market but do not offer electrified heating or smart-control glass products.
