What TMP Fenster + Türen does

TMP Fenster + Türen GmbH is a privately held German manufacturer of windows and doors founded in 1990 and headquartered in Bad Langensalza, Thuringia. The company produces windows (Fenster), front doors (Haustüren), balcony and terrace doors, facades, roller shutters, insect screens, and pleated blinds from Kunststoff (PVC) and Aluminium, certified with the RAL-Gütezeichen quality mark and ranked among the Top 10 window manufacturers in Germany. It operates multiple manufacturing facilities in Germany and a large physical showroom in Bad Langensalza, functioning as a full-service provider across planning, fabrication, installation, and post-sale maintenance.

The company's product backbone combines certified profile systems from three major suppliers — VEKA and GEALAN for PVC, and SCHÜCO for aluminium/PVC — with proprietary or differentiated offerings including CO2-reduced glass supplied as standard, Heizglasfenster (integrated heating glass windows), and the WindowConnect smart home integration system. TMP participated in the federally funded skalVIG research project (mid-2019 to June 2022) led by Fraunhofer to develop industrial-scale vacuum insulated glass, and holds ISO 27001 and EPD certifications supporting its sustainability positioning and access to DGNB/BREEAM-certified projects.

TMP serves four customer segments — private customers (B2C), trade professionals (Fachbetriebe), architects (Architekten), and developers (Bauträger) — through a multi-channel model that combines direct online sales, an accessories e-commerce shop, configurators (e.g., Haustür-Konfigurator), the Bad Langensalza showroom, and a certified Montagepartner installation partner network. Revenue is generated predominantly through one-time product sales, supplemented by professional maintenance services and digital customer tools such as an energy savings calculator and a subsidy assistance service (up to 20% government funding for energy-efficient window replacement). Geographic exposure is exclusively Germany.
