Hans Timm Fensterbau

What Hans Timm Fensterbau does

Hans Timm Fensterbau GmbH & Co. KG is a privately held, family-owned German manufacturer of custom windows, doors, lift-and-slide doors, and facade systems, founded in Berlin in 1957 and currently in its second/third generation of family leadership (Detlef Timm, Bernd Timm, and Bastian Timm). The company operates three production facilities in Berlin-Marienfelde totaling 14,400 m² with 150+ employees, running European-leading HOMAG CENTATEQ CNC machinery under an end-to-end digitalized production stack. It fabricates in four material categories — wood, wood-aluminum, aluminum, and steel — sourced through technology partnerships with Schüco, Jansen, and RP Technik, and offers certified security products up to RC3 (burglar resistance) and FB4 (bullet resistance), as well as Passive House and Cradle to Cradle-certified systems.

The business is anchored in four customer segments: architects and building owners in the object (commercial) business, federal and state government institutions, monument-protection and heritage buildings, and luxury residential villa construction. Reference projects include four federal ministries (Food & Agriculture; Family Affairs; Health; Environment), the Staatsbibliothek Unter den Linden, A. Lange & Söhne, Soho House Berlin, Das Stue Hotel, Siemens Energy headquarters, and the Max-Taut-Schule. A proprietary Runderneuerung renovation methodology (codified as VFF-Leitfaden HO.09) and the TIMM-Modul modular facade system underpin a domain specialization in heritage-protected fenestration that competitors rarely match. The company also holds LKA listing as an approved German security-window manufacturer.

Revenue is generated through project-based, quote-driven sales of custom manufactured products, professional installation with the firm's own logistics fleet, and recurring maintenance/service contracts, with all distribution conducted via direct enterprise field sales across Germany. The firm received the 'Fensterbauer des Jahres 2024' (Window Manufacturer of the Year 2024) award for Product Development and Production.

Product overview

Hans Timm Fensterbau is a comprehensive window and facade manufacturer offering products across four material categories (wood, wood-aluminum, aluminum, and steel) organized into distinct product families.

Expansion highlights5 records

Regional players

• Weru: German mid-market window and door manufacturer with strong regional presence. Comparable to TIMM in German market exposure and residential/commercial custom fabrication, though positioned at lower price points than TIMM's premium tier.

Direct peers

• Kneer-Südfenster: German premium wood and wood-aluminum window manufacturer serving high-end residential and architectural projects. Closely comparable to TIMM's TIMM W wood window series and heritage/energy-efficient positioning.
• Reynaers Aluminium: Belgian premium aluminum window, door, and facade system manufacturer serving architects and developers across Europe. Directly comparable to TIMM's aluminum and facade offerings for high-end architectural projects.
• Internorm: Austrian premium window and door manufacturer specializing in wood, wood-aluminum, and uPVC systems for high-end residential and commercial projects. Highly comparable to TIMM in multi-material positioning, custom fabrication, and luxury/homeowner customer base.
• Gutmann Aluminium-Systeme: German aluminum window, door, and facade manufacturer focused on premium architectural projects. Comparable to TIMM in aluminum fabrication, facade system offerings, and project-based enterprise sales in the German market.

Broad incumbents

• Jansen: Swiss steel profile systems manufacturer supplying steel window and door solutions (including Art'15 and Arte 2.0). TIMM uses Jansen as a steel systems supplier but Jansen also sells direct to fabricators, making it both a partner and competitor.
• Schüco International: One of Europe's largest aluminum window, door, and facade system manufacturers. Schüco is both a technology supplier and a direct competitor to TIMM in premium aluminum fenestration, with broader geographic reach and a larger product portfolio.
• Rehau Windows: Large polymer and polymer-aluminum window systems manufacturer with broad European presence. Competes with TIMM in residential and light commercial window categories, though Rehau's brand is positioned more broadly than TIMM's specialist custom focus.

Others

• HOMAG Group: German CNC machinery manufacturer and TIMM's core technology partner for window production equipment. Included as an ecosystem enabler rather than a direct competitor — HOMAG's solutions underpin TIMM's production capability and serve the broader fenestration manufacturing industry.

Emerging players

• RP Technik: German steel profile systems manufacturer specializing in narrow-profile steel windows and doors for heritage and high-security applications. Closely comparable to TIMM's steel product line and the Fineline/Hermetic systems TIMM resells.
