What Sunflex Aluminiumsysteme Gmbh does

SUNFLEX Aluminiumsysteme GmbH is a German manufacturer of premium aluminum glass systems headquartered in Wenden-Gerlingen, with the current legal entity established in 1986 (the Schneider family business traces back to Schneider Rolladen und Markisen, founded 1963). The company designs, produces, and distributes sliding systems, sliding window systems (SF40, SF60, SF80 variants with progressively higher thermal insulation), sliding-turning systems, folding sliding systems, horizontal sliding wall systems, glass room dividers, loggia glazing, and aluminum terrace roofs (SF125, SF150, SF300 variants). Its product range has been continuously extended since inception and spans non-insulated through highly thermally insulated system families, marketed on quality, durability, configurability, and ease of handling.

The company operates a hybrid B2B2C and direct-channel go-to-market: end customers configure products via the SUNFLEX Konfigurator (konfigurator.sunflex.de), and resulting leads are forwarded to authorized regional specialist dealers (Fachpartner) for quoting and installation. Distribution is supported by five wholly-owned regional subsidiaries in South Africa (Durban, 2005), the Middle East (UAE/Dubai, 2007), the USA (Naples FL, 2008), Asia (Thailand, 2009), and Latin America (Mexico/Puebla, 2012), combined with a dealer network exceeding 100 partners across more than 40 countries. Manufacturing is concentrated at the Wenden-Gerlingen headquarters and a production facility in Friesenhagen (acquired 1988). Headcount is stated at approximately 350 employees.

SUNFLEX is a privately held family-owned GmbH with no institutional investment, funding rounds, or public listing. Leadership transitioned in 2020 when founder Ernst Schneider retired and Dennis Schneider, Melanie Feldmann, and Nicolas Schneider took over Geschäftsführung. Revenue is not publicly disclosed. Marketing channels include a multilingual website in 8 languages, the online configurator, and major industry trade fairs (Fensterbau Frontale, Batimat Paris). Standard digital marketing integrations (Google, Microsoft, Meta, Stape, Matelso, Rapidmail) and an online configurator represent the company's primary technology/digital layer; no AI/ML capability is referenced.
