Wintec Lux

A Luxembourgish industrial company based in Wemperhardt (municipality of Weiswampach, in the very north of the Grand Duchy, on the Belgian-German border), Wintec Lux S.à r.l. specializes in the manufacturing and installation of innovative window systems. Led by Ms. Helga RAUW, the company stands out for its integrated model — design, in-house production, consulting, and installation — and for its unique specialty in Luxembourg: frameless aluminum windows (rahmenlos). Its philosophy is based on four fundamental pillars — Development, Innovation, Sustainability, and Quality —, with systems meeting the Passivhaus (passive house) standard and constantly perfected to remain « always a step ahead ».

Wintec offers a complete range of window systems: its flagship product Zero Systems (frameless windows, post-and-beam systems, sliding elements, entrance doors), pre-frames (Blindrahmen) optimized for the construction phase, as well as classic windows and sliding systems in aluminum, PVC, or wood. The company also specializes in renovation and heritage protection (Denkmalschutz), with tailor-made solutions combining authenticity and energy efficiency for historic buildings. Wintec complements its offer with solar shading systems: external venetian blinds (raffstores), roller shutters, and screen blinds. Its clientele includes high-end private individuals, architects, builders, developers, and public authorities, throughout the Grand Duchy and the Greater cross-border Region.
