Lumon Suomi Oy

What Lumon Suomi Oy does

Lumon Suomi Oy is a Finnish family-owned manufacturer and installer specializing in frameless retractable balcony and terrace glazing systems. Founded in 1978 and headquartered in Kouvola, Finland, the company designs, produces, and installs architectural glazing, railing, terrace roof, and visor blind systems for residential and commercial buildings. Its core product is a frameless sliding glass panel system engineered for balcony enclosures, with a stated operational lifespan exceeding 30 years. The company is owned by the parent holding company Lumon Invest Oy and is led by CEO Olli Vanska.

The company operates its own manufacturing facilities in Finland, Spain, and Canada, complemented by factory-trained certified installation crews rather than third-party subcontractors. Lumon serves more than one million customers across 20 countries on four continents, targeting homeowners, housing associations, building contractors, developers, and architects. Distribution combines wholly-owned subsidiaries in primary European and North American markets with a growing dealer network in the United States and Canada as of 2025. Revenue was EUR 159 million in 2025 versus EUR 149 million in 2024, and the company employs over 1,000 people worldwide.

Lumon monetizes through direct sales of manufactured glazing and adjacent systems paired with installation services, supplemented by maintenance contracts. The product portfolio includes Lumon Glazing (the core frameless balcony system), Lumon Railing (glass and post-and-rail systems), Lumon Roof (terrace roofing), Visor Blinds (retractable solar shading, sold in part through e-commerce), and maintenance services. Digital sales-enablement layers include the Lumonizer AI visualization tool and Building Information Modeling (BIM) integrations via platforms such as BIMObject and ProdLib, which support product specification by architects and contractors. Strategic priorities in 2025 include a company-wide strategy renewal, expanded North American dealer coverage, entry into Czechia, Slovakia, and Portugal, and a new HoReCa hospitality customer segment.
