What Theuma does

Theuma is a privately held Belgian-headquartered manufacturer of industrial-scale interior doorsets — pre-assembled door-and-frame units — operating across Benelux with production facilities in Bekkevoort (Belgium) and Nijkerk (Netherlands) and approximately 250 employees. Its product portfolio covers standard, fire-resistant, soundproof, burglar-resistant, smoke-resistant, climate-stable, sliding, and swing doorsets, plus design lines (Vision, Flow, Connection, glass) and the CarePlus sub-brand for healthcare sliding walls. Core technical differentiation rests on two proprietary finishing technologies: EBC (Electron Beam Curing) lacquer, claimed to use only 20% of the energy of traditional UV lacquering while producing a 100%-cured matte scratch-resistant surface (extended in August 2023 with the EBC Intense White and Black variants), and EPC (Electrostatic Powder Coating) for steel frames; the Nijkerk site also runs the SmartDoorFactory robotic assembly line installed in 2022.

Theuma operates a hybrid B2B go-to-market: direct field sales through Theuma Projects for complex utility builds (healthcare, hospitality, education, government, residential) and a network of selected dealers in the Netherlands including DeurdeDeur, Jongeneel, Stiho, Houthandel Spakenburg, HDC Beilen, Bouwcenter, and BMN Bouwmaterialen. Revenue is generated primarily through hardware sales of doorsets and frames, supplemented by professional services under a 'Total Service Concept' covering work preparation, site coordination, and installation. The customer base spans project developers, contractors, architects, installers, and institutions — Marriott Sapphire Hotel Antwerp, Orpea care homes, Binck City Park, Paleis van Justitie Den Bosch are named references — supported by partnerships including Häfele for hotel doorsets and the GND quality-label scheme (cumulative one million labels as of June 2022). The company holds a deep certification stack (ISO 9001:2015, FSC covering 99% of wooden doors, BREEAM/LEED contribution documentation, fire-resistance ratings) and is pursuing Cradle to Cradle Silver by end of 2025.
