What Josko does

Josko Fenster und Türen GmbH is an Austrian family-owned manufacturer of premium windows, sliding doors, front doors, and interior doors, founded in 1960 by Johann Scheuringer and headquartered in Kopfing im Innkreis, Upper Austria. The company operates within the Josko-Scheuringer Group, which also includes Eurosun (sun protection products, acquired 2016) and Glastech (insulating glass, acquired October 2024), together employing 1,167 people and generating €212 million in consolidated turnover. Josko serves two primary customer segments: architects and B2B construction professionals who specify products in residential and commercial projects, and premium residential homeowners purchasing windows and doors for new construction or renovation. The company reaches these customers through a single-brand distribution network of 70 partner showrooms across 10 countries in Europe and North America, supplemented by a dedicated B2B/Architects channel and direct customer inquiries routed to local partners.

The product portfolio is anchored in in-house manufacturing of aluminium, wood/aluminium, and uPVC/aluminium window and door systems, with the patented MET 56 invisible frame system and the "Smart Mix" coordinated product philosophy serving as key technical differentiators. Vertical integration—encompassing raw materials, insulating glass production (Glastech), and sun protection (Eurosun)—allows all components to be technically and visually coordinated. Flagship product lines include ONE (coordinated complete system for windows and sliding doors), Nevos Glass (avant-garde glass-surface front doors), Securance (RC2/RC3 security doors with 43dB sound insulation and fire protection), MET Loft (slim-profile interior doors), Easy Screen Zip (wind-resistant awnings up to 100 km/h), and Easy Raff (venetian blinds covering up to 16 m² in a single piece). The group holds design credentials including 7 Red Dot Awards and 6 German Design Awards and has been Austria's market leader for wood/aluminium windows for nearly 25 years.

Josko operates a sales-led go-to-market through independent sales, installation, and service partners, with revenue generated primarily via one-time, project-based sales of custom-manufactured premium windows and doors. Pricing is quote-driven and varies by material, dimensions, finishes, and specifications; no public pricing is offered. In 2024, windows and all-glass systems (including sun shading) accounted for 69.3% of Josko revenue, front doors 9.5%, and interior doors 7.2%. Consolidated revenue progressed from €179.3M (Josko standalone, 2024) to €196M (Josko total, 2025 projected) to €212M (group, 2026), reflecting both organic growth in the core product portfolio and acquisition-driven expansion via the Glastech integration. The company is privately held by the Scheuringer family, with no external institutional investment disclosed, and is led by Johann Scheuringer (CEO & majority owner), Stefan Wagner (CSO & CFO), and Gerhard Kasbauer (COO).

• Schüco: German global leader in aluminium and steel window, door, and façade systems. Comparable on premium aluminium products and project-based selling to architects, but operates at much larger scale and across commercial as well as residential segments.
• Saint-Gobain (Distribution & Glass): Global building materials giant with a sizable window, glass, and façade business across Europe. Comparable on the insulating glass and integrated building envelope dimension, but operates at vastly greater scale and breadth than Josko.
