What Türenmann does

TÜRENMANN Stuttgart GmbH & Co. KG is a privately held German specialist retailer and installer of windows, doors, glass, and sun protection systems headquartered at Leobener Straße 104 in Stuttgart Feuerbach. The company operates from a single location serving the Stuttgart region in Baden-Württemberg, with three managing directors (Ralph Werner, Matthias Groß, Christian Pommerer) and claims over 50 years of operating history in the building-trades channel.

The company's product portfolio spans five core categories: windows (PVC, aluminum, wood, wood-aluminum, roof, monument-protection, fire-protection, and security variants); doors (entrance, apartment, interior, security, and functional/fire-protection doors, plus a digital door configurator); glass systems (insulating glass, soundproofing, storefronts, full-glass doors, conservatories, and repair glazing); sun protection (roller shutters, external venetian blinds, textile shades, awnings, and jalousies); and hardware technology (retrofit security, handle sets, locking systems, door closers, emergency-exit systems). TÜRENMANN also sells supporting products including patio roofs and canopies, and runs a digital door configurator at konfigurator.tueren-mann.de. Products are sourced through partnerships with major manufacturers including Schücco, Teckentrup, Novoferm, Hörmann, Velux, Siegenia, Somfy, Unilux, Jeld-Wen, Alulux, Geze, and Dormakaba.

TÜRENMANN operates a sales-led go-to-market focused on direct customer outreach (phone, email, contact forms) and on-site consultation, with an emergency repair hotline and a referral-driven acquisition motion. Revenue is generated primarily through one-time project sales and installation of windows, doors, glass, and sun protection, supplemented by recurring maintenance contracts (Wartungsverträge), repair services (Reparaturservice), and government subsidy consultation (Fördermittelberatung, including KfW/EU programs). The customer base is horizontal across three segments — residential homeowners (primary), commercial properties, and public institutions — all within the Stuttgart regional market. An AI phone assistant (HalloPetra) handles call intake, routing, and appointment scheduling. Pricing is quote-based and not publicly disclosed; labor rates from the published AGB are €62.00/hour with travel and overtime surcharges.

Scale indicators4 records

Expansion highlights6 records

Others

• Velux: Global roof window (Dachfenster) manufacturer. Partner of TÜRENMANN whose products are resold and installed. Relevant as a fenster industry player and brand reference rather than a direct fenster retailer competitor.
• Schüco: German fenster, door, and façade systems manufacturer. Partner of TÜRENMANN whose aluminum fenster and door products are resold and installed. Comparable as an industry player though operating at the manufacturing tier rather than retail/installation.
• Hörmann: European market leader for doors and door systems (residential and commercial). Partner of TÜRENMANN whose door products are resold and installed, representing an upstream supplier rather than a direct installer competitor.

Broad incumbents

• Hornbach: Large German DIY/home improvement chain (Hornbach Baumarkt AG) selling fenster, tür, and sun protection products. Comparable to TÜRENMANN's retail offering but with a much broader product range and professional contractor focus.
• OBI: Leading German and European DIY chain carrying fenster, tür, and sun protection products. Comparable product overlap with TÜRENMANN but a broad-market retailer rather than a fenster/tür specialist installer.
• toom Baumarkt: German DIY chain (part of REWE Group) selling fenster, tür, glass, and sun protection products with installation services in select locations. Comparable product categories to TÜRENMANN but at national scale rather than regional specialty.
• BAUHAUS AG: Major European DIY and home improvement chain selling windows, doors, glass, and sun protection products across Germany. Overlaps with TÜRENMANN's product categories but operates as a broad DIY retailer rather than a specialist fenster/tür installer serving the Stuttgart region.

Emerging players

• Warema: German specialist manufacturer of sun protection systems (roller shutters, external Venetian blinds, awnings). Overlaps directly with TÜRENMANN's sun protection category and serves both direct consumers and installers in Germany.

Direct peers

• Finstral: South Tyrolean fenster and tür manufacturer selling direct to end-customers with its own installation network in Germany and Italy. Comparable in combining fenster/tür sales with professional installation services for residential customers.
• Internorm: Austrian fenster manufacturer with first-window-to-installation sales and service network active across Germany. Direct competitor in fenster/door sales and professional installation, with similar product breadth and energy-efficiency positioning.
