Nowak Glas

What Nowak Glas does

Nowak Glas (legal name J. Nowak Glas GmbH & Co. KG, with operating entities in Marl, Wesel, and Gladbeck) is a German family-owned B2B glass processor and trader headquartered in Bochum-Wattenscheid, founded by Josef Nowak in 1964 and now run by the second generation. The company manufactures and processes a comprehensive portfolio centered on functional insulation glass (ISOPANE brand), safety glass (ESG, VSG, TVG), and basic flat glass products, with broad finishing capabilities including ceramic printing, sandblasting, UV bonding, glass painting, curved glass (eight furnaces), and fluted bevels. Notable technical differentiators include a DIBt national approval (No. Z-70.4-125) for heat-strengthened TVG and the proprietary ISOLETTE integrated blind-insulation glass system.

Nowak Glas operates across four production sites totaling roughly 110,000 square meters of premises at the Bochum headquarters alone, with combined daily output of approximately 9,000 ISOPANE functional insulation glass units across factories in Bochum, Marl, and Wesel, each operating multiple production lines in multiple shifts. Maximum unit dimensions reach 6.00 x 3.21 m and 1,000 kg, positioning the company for large-format facade and architectural projects. The group also holds minority stakeholdings in Euroglas GmbH at Haldensleben and Osterweddingen, providing upstream exposure into flat glass production.

Revenue is generated primarily through direct B2B sales to glaziers, construction companies, architects, and building developers in Germany, the Netherlands, and Belgium, with separate sales departments per product category at each location. The business model combines hardware sales (processed glass), glass trading/wholesale, and contract processing services (Lohnvorspannen, grinding, finishing). Pricing is quote-based with standard price-list surcharges, minimum order value thresholds, and a silver-mirror surcharge indexed to LBMA silver prices; private individuals are explicitly directed elsewhere. Marketing is trade-oriented (fensterbau|frontale, glasstec, Glaskon, Bundesverband Flachglas affiliations), and ownership remains concentrated within the Nowak family with no external equity capital disclosed.
