Profin

What Profin does

Profin Oy is a Finnish manufacturer founded in 1977, headquartered in Pudasjärvi, that produces wood-framed glass sliding walls, fixed windows, glass sliding doors, and related accessories. The company operates as a subsidiary of Inwido AB, Europe's largest windows and doors manufacturer, following its 2018 acquisition. Profin is the recognized market leader in Finland for glass sliding doors in both multi-story apartment buildings and single-family homes, serving construction industry clients (building companies and developers), architects and designers, prefabricated house manufacturers (talotehtaat), and end-consumers via direct and showroom-based sales channels.

Profin's product portfolio is anchored by three core lines: outdoor glass sliding walls (SD Active all-wood and SD Clear aluminum-clad variants), interior sliding walls (Indoor and the threshold-free Indoor Air launched in 2024), and the proprietary 5-in-1 prefabricated building elements that integrate windows, doors, and wall structures into single installation-ready units. The manufacturing process incorporates the Japanese Masame timber cutting technique, earthquake-resistant corner joints, and dense laminated timber frames with 6–15 lamellas for structural rigidity. Profin is the only glass sliding wall in Finland recommended by VTT for extreme conditions, with documented air tightness class 4 (ratio 0.2), rain tightness E1500 (1500 kPa), wind load resistance C5, thermal performance (U-values 0.64–0.79 W/m²K), and acoustic insulation up to Rw+Ctr 40 dB.

Profin operates a custom-manufactured, made-to-order hardware sales model with quote-based pricing that is not publicly disclosed. Go-to-market combines direct field sales teams organized by customer segment and Finnish region (Uusimaa, Pirkanmaa, Southwest, Southeast), a dedicated architect services team with ProdLib BIM integration for ArchiCAD and Revit, the Profin ETÄ remote consultation service, and showroom operations in Vantaa. Marketing relies heavily on Finnish housing fair (Asuntomessut) participation — Profin products have been featured in approximately half of recent housing fair projects, including 8 projects at Oulu 2025 — alongside professional trade press coverage and downloadable brochures. International exports to Japan date from the 1990s; current standalone revenue figures are not publicly disclosed, with the most recent disclosed financial profile showing approximately €13 million in revenue with 85 employees at the 2017 40th anniversary milestone.
