Unilux Gmbh

What Unilux Gmbh does

UNILUX GmbH is a privately held German manufacturer of premium, customized windows, doors, and glass facades, headquartered in Salmtal near Trier and founded in 1955 by master carpenter Nikolaus Meeth. The company operates four material platforms — wood-aluminum (LivingLine, ModernLine, DesignLine, DesignLine Privacy, PureLine), wood (Classic, Stil, Denkmal), plastic-aluminum (IsoStar-Alu), and plastic (IsoStar, IsoPlus) — alongside a door portfolio spanning front doors (UniqueLine, MultiLine, aluminum, plastic, side-entry), lift-and-slide and slide-fold terrace systems, and the extra-large JumboLine. Glass facades include the FineLine post-and-rail system and the OpenView full-glass corner, with the patent-pending UNILUX Plano barrier-free threshold covering accessibility. Differentiated specifications include Uw-values down to 0.73 W/(m²K) meeting passive house standards, RC2-certified front doors, and FSC/PEFC-certified wood sourcing.

UNILUX generates revenue through hardware sales of manufactured windows, doors, glass facades, and accessories (roller shutters, blinds, insect screens, handles, glazing bars), with pricing handled quote-by-quote through its exclusive network of over 500 authorized specialist partners (Fachpartner) across Germany and selected export markets. The GTM is channel-led: the Salmtal-based company supports partners with technical training, marketing, and architect-facing resources, complemented by a dedicated showroom (Kompetenzcenter), a partner/architect login portal, and Google AdWords demand capture. Headcount is approximately 300. No direct revenue figures are publicly disclosed; mid-sized German premium window/door manufacturers in this segment with HBI added typically operate in the tens of millions to low hundreds of millions of euros range. Certifications include ISO 9001, ISO 50001 (renewed November 2023), FSC-C119212, PEFC, CE, DIN EN 18040, RC2, and KfW-funding eligibility on relevant products.
