What fentec does

Fentec GmbH is a privately held German limited liability company headquartered at Karlsruher Allee 2 in Ludwigsburg, specializing in the supply and installation of windows, doors, roller shutters, and blinds. The company was renamed from a predecessor entity to FENTEC in April 2007 and converted from a sole proprietorship (Einzelfirma) into a GmbH in August 2009. The firm offers an end-to-end service bundle covering consultation, on-site technical measurement (Aufmaß), product supply, and professional installation.

The product portfolio is sourced exclusively from three branded European manufacturers: Schüco (plastic and aluminum windows, aluminum front doors including Corona CT 70, SI 82, and SI 82+ profile systems), Rehau (plastic window profiles including Brillant Design and Geneo, the latter capable of passive-house standards), and Reflexa (roller shutters in Vorbaurollladen and Aufsatzrollladen variants). All products carry CE marking. Material options span plastic, aluminum, wood, and wood-aluminum constructions. Fentec does not manufacture any of the products it sells; its differentiation rests on full-service bundling and access to premium supplier systems.

Commercially, Fentec operates a dual-channel model: direct sales to residential and small-commercial end customers in Germany (with reference projects including multi-family apartment buildings of 15 to 54 units, sports clubs, and cultural centers in the Ludwigsburg/Stuttgart region) and wholesale supply to Stützpunkthändler (dealer partners) in France and Belgium. Pricing is quote-based rather than publicly listed. The firm is founder-owned, with no disclosed venture capital or institutional backing, and had up to twelve employees (eight installers and four office staff) during its prior growth period according to company history. No revenue, funding, or financial performance data is disclosed in available sources.
