What Duco does

Duco is a Belgian ventilation and sun-control specialist founded in 1991 and headquartered in Veurne, operating through two divisions: DUCO Ventilation (residential window ventilation, mechanical ventilation units such as the DucoBox range, and demand-controlled natural ventilation systems) and DUCO Projects (intensive ventilation, continuous louvre walls, louvre doors, and architectural solar shading including DucoSun and DucoSlide). Its product portfolio integrates natural ventilation, mechanical extraction, acoustic attenuation (up to 17 dB), intrusion resistance (RC2-certified DucoDoor), and solar shading (up to 63% cooling-load reduction) with smart-building connectivity via a REST API / ModBus TCP Connectivity Board.

The company sells primarily B2B through a network of wholesalers and distributors complemented by dedicated field-sales and project-support teams serving architects, HVAC installers, window manufacturers, building developers, and project specifiers. Distribution is supported by country-specific websites across Belgium, the Netherlands, France, Luxembourg, the UK, Ireland, and Germany, plus dealer portals, BIM libraries, DUCO Academy training, and an installer mobile app. Showcase customers span education (Schulbauoffensive Berlin, Atheneum Pegasus), data centres (Colt FRA 3 Frankfurt, Jupiter MDC Jülich), retail (LIDL Luton, Migros Chur), and high-rise residential (London developments including Bailey Point, Watling Place, and Faraday House).

Duco is a privately held company with no disclosed parent, funding rounds, or public revenue. Recent strategic activity in 2026 includes the launch of the DucoVent Family product line, the DucoSun Cubic InsertFit architectural shading system, re-certification under the VCDO sustainability charter, VKG and VMRG quality certifications, and the Duco Connectivity Board with REST API / ModBus TCP integration for building management systems. The business model is hardware-led with a recurring services layer (consulting, installation support, training), and pricing is quote-based rather than list-priced.
